Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the key element and carrier are assembled separately before mounting on the housing, then the key element can be securely fastened to the housing, but the assembly process becomes complex and labor-intensive
Solution Approach 1:
The key element and carrier are merged into a single integrated component that is directly mounted on the housing. This eliminates the separate assembly step of fastening the key element to the carrier, thereby simplifying the overall assembly process while maintaining the fastening reliability through the direct mounting structure.
2Adaptability or versatility
If multiple separate parts are used for the key element assembly, then each part can be optimized for its specific function, but the number of parts increases and assembly expense rises
Solution Approach 1:
Multiple functional parts (key element and carrier) are combined into a single integrated assembly that can be directly mounted on the housing. This reduces the total number of parts while preserving the functional optimization through the integrated design that incorporates all necessary features within the unified structure.
3Manufacturing precision
If manual assembly of the key element on the carrier is required, then precise alignment can be achieved, but assembly time and labor costs increase
Solution Approach 1:
The key element and carrier are integrated into a single unit that is pre-aligned during manufacturing, eliminating the need for manual alignment during assembly. This maintains manufacturing precision through integrated production while significantly improving assembly productivity by reducing the assembly steps to a simple mounting operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies assembly, reduces part count, and ensures reliable activation and sealing of electrical components, enhancing assembly efficiency and user experience through elastic deformation and secure mounting.
Implementation Method 1
The key element, on the other hand, is made to be elastic in its material properties, so as to absorb a pressing force acting from the outside, while at the same time the contact means is elastically deformed accordingly and this brings about an activation of the electrical and/or electronic component.
