Now there are three judgments in the mechanical or electric coin mechanism , involved shapes , materials and weight . Mechanical coin mechanism usually measures by slits and cradles . Slits are constructed by slanting channels , they are like the arranging mechanisms of automatic productions . Electric coin mechanisms differentiate from the different coins by examining the variation of voltages when coins pass through electric coils . Actually , the traditional coin mechanisms still have many disadvantages , so we will adopt the multi-function way to raise the identifying ability . This research uses the TRIZ method during the design process and operates the contradiction matrix to find out the feasible and requisite design . We believe that this research could be good for the market development of coin mechanisms .

Fiomi Diagnostics AB manufactures and develops point of care cassettes for bloodsamples to determine risk of myocardial infarction and heart failure for use within thehealthcare sector. The cassette contains of three main parts; top, bottom and a plasticchip. The bottom parts are delivered directly from the supplier to the assembly linewhile the top part has to be prepared with a membrane for blood separation byultrasonic welding before it can be sent to the assembly line. At present the top parts are provided with the membranes a floor below theassembly line and therefore have to be transported by carriers to the assembly line.These carriers are currently designed as large plates (400 x 600 mm) with a capacityof 120 top parts, but they are space consuming at the ultrasonic welder as well at theassembly line.To solve this lack of space the operators often place the platesdiagonally behind themselves where room is available. This causes ergonomicproblems due to the many twists of the upper body conducted at both processes. To solve the ergonomic problems this thesis work were initiated to develop a newmore agile carrier between the two processes. During the thesis work TRIZ wereused to trigger creative concepts, choose among them and combine the good ideasfrom different concepts. After the conceptual phase different manufacturing methodswere explored. To be certain that the concept could be manufactured by specificmanufacturing process different manufactures were contacted to help out with whatwould make the concept suitable for the specific method. The manufacturing methodsexamined were: injection molding, plastic and aluminum extrusion, vacuum molding,additive manufacturing and sheet metal bending. Prototypes of the three best concepts were created by 3D-printing to be evaluatedby the operators whom in the future might be using the new carriers. Complementedwith an evaluation of the carriers economic and performance data, a recommendationof which carrier should be selected were concluded. The result was a carrier manufactured by sheet metal bending with a pattern cut outwhich allows for the top parts to hang in the carrier. The design has a capacity of 60top parts which is half of the current carrier, but with a base area of a sixth of thecurrent carrier gives the new design an increase in surface efficiency by 300 %. Due tothe low order size the sheet metal alternative was the cheapest alternative. / Fiomi Diagnostics AB tillverkar och utvecklar patientnära blodprovskassetter för attidentifiera risk för hjärtinfarkt och hjärtsvikt för att användas inom hälsovården.Kassetterna består av tre huvuddelar, en överdel, en underdel samt ett plastchip.Underdelarna kommer direkt från leverantör till monteringen medan överdelarna måsteförses med ett blodseparationsmembran genom ultraljudssvets innan det kan skickas tillmonteringen. I dagsläget förses överdelarna med blodseparationsmembran på våningen undermonteringen och måste därför transporteras på bärare till monteringen. Dessa bärare äridag stora plåtar (400 x 600 mm) som rymmer 120 kassettöverdelar, men som ärskrymmande både vid ultraljudsprocessen och vid monteringen. För att lösa platsbristenställer operatörerna dessa plåtar ofta snett bakom sig där plats finns. Detta skaparergonomiska problem då många vridningar av överkroppen sker vid båda processerna. För att lösa de ergonomiska problemen initierades detta examensarbete för att ta fram enny smidigare bärare mellan processerna. I arbetet så används TRIZ för att genererakreativa koncept samt sålla bland dessa och kombinera det som var bra från ett koncepttill andra. Efter konceptfasen utforskades olika produktionstekniker för att tillverkakoncepten. För att veta att koncepten kunde tillverkas för tänkt tillverkningsmetodkontaktades tillverkare och tillfrågades vad som krävdes för att metoden skulle varagenomförbar. Tillverkningsmetoder som utforskades var; formsprutning, extrusion avplast samt aluminium, vakuumformning, additiv tillverkning samt plåtbockning. Prototyper togs fram med hjälp av 3D-printer av de tre bästa alternativen för att utvärderasav operatörerna som i framtiden kan komma att använda dessa. Tillsamman med enutvärdering av bärarnas ekonomi och prestanda utsågs en rekommendation av vilkenbärare som bör användas. Resultatet blev en bärare tillverkad genom plåtbockning med utskuret mönster för att låtakassettöverdelarna hänga i den. Designen har en kapacitet för 60 kassettöverdelar vilketär en halvering av den befintliga, men basytan för den nya designen är en sjättedel av denbefintliga bäraren vilket ger en yteffektivitetsökning med 300 %. Då seriestorleken avbärarna var relativt låg så blev plåtalternativet också billigaste av alternativet.

The contributions to knowledge documented in this doctoral thesis are two-fold. The first contribution is in the application of a new biomimetic design tool called BioTRIZ. Its creators claim it can be used to facilitate the transfer of biological principles to solve engineering problems. The core case-study of this thesis documents how this tool was used to frame and systematically explore low-energy solutions to a key technical problem in the underdeveloped field of radiative cooling. Radiative cooling is a passive mechanism through which heat from a building can be rejected to the sky – an abundant but underused natural heat sink. Published in the Journal of Bionic Engineering, the study was the first independent application of BioTRIZ in the academic literature. The second contribution to knowledge is in the design, development and testing of the most promising biomimetic concept to come out of the BioTRIZ radiative cooling study. ‘Heat-selective’ insulation gives a roof mass a cool view of the sky because integrated pathways focus and channel longwave thermal radiation through it. It is biomimetic because it achieves infrared transparency by adding structural hierarchy to the component, rather than manipulating the properties of the material itself. Test panels on a rooftop in central London cooled to between 6 and 13 degrees below ambient temperature on May and April nights. Radiative cooling powers of between 25 and 70 W/m2 were measured when plates were at ambient temperature. Daytime radiative cooling below ambient temperature occurred when clouds blocked direct sunlight. Radiative cooling power was increased by 37% using reflective ‘funnels’. Two additional BioTRIZ analyses are presented as minor case studies. They each attend to a key technical problem in the field of passive thermal energy storage in buildings. They serve to illustrate the type of results that can be expected from using BioTRIZ during low-energy building design.

Evaluating claim conflicts between patents is a crucial issue in patent applications and validity allegations. Existing patent informatics tools do not relate well to the legal requirements of identifying claim conflicts; innovation theory does not address patent evaluations; and the current legal approach has weaknesses in the repeatability between cases. Therefore, a need emerges to design a scientific method for evaluating conflicts between patent claims. This thesis presents research on the topic of identifying, evaluating, and visualising patent conflicts. ‘Conflict’ is used to have the same meaning as obviousness, which is an essential legal term under the UK Patents Act 1977. Building on existing methods, this research provides a novel method called Criteria-Based Patent Mapping, for assessing claim conflicts between patents. ‘Criteria-Based’ means that this assessment uses evaluation criteria that clarify the inventive step of the patent. The source of these criteria is the well-known Theory of Inventive Problem Solving (TRIZ), which is incorporated into a statistical method of 'Patent Mapping' for evaluating and visualising differences between patent claims. The application of the new method to four case studies shows that there are differences in judging standards between the legal authorities; and also shows an average value of 52% agreement in predicting potential conflicts between patent claims. Based upon these results, the original 39 TRIZ parameters can usually be refined to about 12 criteria. The scope of this method is restricted to patents in mechanical engineering due to the relevancy of TRIZ parameters. This research transforms difficult claim-to-claim evaluations into simpler claim-to-criteria comparisons that lead to more efficient and transparent patent evaluations. Such improvements will be useful for better decision-making in patent strategy.
