Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the area of the printed circuit board is reduced to accommodate conductive connection members, then the passage region and sealing region for conductive connection members are secured, but the space for placing electronic components decreases
Solution Approach 1:
The patent introduces a recess in the support member that extends in the thickness direction (z-axis), creating a three-dimensional space. This allows the printed circuit board to utilize vertical space rather than only horizontal plane area, effectively increasing the available area for both circuit board placement and electronic components without conflicting with the conductive connection member passage region.
Solution Approach 2:
The recess structure embeds the printed circuit board within the support member's thickness direction. The circuit board is positioned such that part of it extends into the recess space, nesting the circuit board and electronic components within the vertical dimension of the support member, thereby resolving the area conflict.
2Area of stationary object
If the area of the printed circuit board is reduced, then passage region for conductive connection members is secured, but it becomes difficult to connect the first and second printed circuit boards using a single conductive connection member
Solution Approach 1:
The recess provides vertical clearance in the thickness direction, allowing a single conductive connection member to pass through both the first and second printed circuit boards without requiring the boards to be positioned in multiple separate locations. The extended space accommodates the connection member's path through both boards, simplifying the connection structure.
3Area of stationary object
If the area of the printed circuit board is reduced, then sealing region for conductive connection members is secured, but the space for placing electronic components decreases
Solution Approach 1:
The recess structure creates a dedicated vertical space that separates the circuit board placement area from the sealing region. The conductive connection members can pass through the support member in the thickness direction with proper sealing, while the circuit board and electronic components utilize the horizontal and vertical space within the recess, maintaining both sealing effectiveness and component placement space.
