Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the position of the movable electrode is changed to improve design flexibility, then the adaptability of the switch body is improved, but the positions of the fixed electrodes must be changed which increases device complexity and manufacturing difficulty
Solution Approach 1:
The movable electrode is divided into a movable electrode body and a separate movable contact member that can be positioned independently. This segmentation allows the movable contact member to be adjusted to different positions while the fixed electrodes remain in their original positions, enabling design flexibility without requiring changes to the fixed electrode layout.
Solution Approach 2:
The movable contact member is designed to be movable relative to the movable electrode body, allowing it to be positioned at different locations. This dynamic positioning capability enables the switch body to adapt to different design requirements while maintaining the same fixed electrode configuration, thus improving adaptability without increasing device complexity.
2Adaptability or versatility
If the position of the movable electrode is changed to improve design flexibility, then the adaptability of the switch body is improved, but the fixed electrode layout must be altered which increases manufacturing difficulty
Solution Approach 1:
By segmenting the movable electrode into a movable electrode body and a separate movable contact member, the invention allows the movable contact member to be repositioned without changing the fixed electrode layout. This segmentation enables design flexibility while keeping the fixed electrode manufacturing process unchanged, thus improving ease of manufacture.
Solution Approach 2:
The movable contact member is designed to be self-positionable on the movable electrode body through its elastic deformation characteristics. When pressed, the movable contact member deforms and makes contact with different fixed electrodes based on its position, eliminating the need for complex positioning mechanisms and reducing manufacturing difficulty.
3Device complexity
If the movable electrode position is fixed to simplify the structure, then the device complexity is reduced, but the adaptability of the switch body deteriorates
Solution Approach 1:
The movable contact member is designed with dynamic positioning capability, allowing it to be placed at different positions on the movable electrode body. This dynamic feature provides adaptability while maintaining a simple overall structure, as the movable contact member can be repositioned without adding complex mechanisms to the switch body structure.
Solution Approach 2:
The position of the movable contact member can be changed by adjusting its mounting location on the movable electrode body, which is a simple parameter change. This allows the switch body to be adapted to different applications by simply changing the position parameter of the movable contact member, maintaining structural simplicity while improving adaptability.

AI summary
The switch body includes: a wiring substrate where first to fourth fixed contact members are formed; and a movable contact member including a pressure receiving part opposite from the second fixed contact member, a first outer edge facing the first fixed contact member, and a second outer edge facing the third fixed contact member. The fourth fixed contact member is formed in a region outside a projection region being a projection of the movable contact member on the wiring substrate and is in a position facing the first outer edge when the second outer edge is moved to a region where the second fixed contact member is formed.
