Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional connector devices are used to connect camera components to the main circuit board, then electrical connection is achieved, but the mounting space is excessively large and the device volume increases
Solution Approach 1:
The patent extracts the essential function of electrical connection from the traditional bulky connector device and implements it through flexible connecting members that are integrated into the circuit board structure. This removes the separate connector component and reduces overall device volume while maintaining the electrical connection function.
Solution Approach 2:
The patent transitions from planar connector layouts to three-dimensional stacked arrangements of flexible connecting members. Multiple connecting members are arranged in different layers and connected through vertical vias, utilizing the Z-dimension to reduce the footprint area while maintaining all necessary electrical connections.
2Area of stationary object
If multiple camera components are assembled with separate connector devices, then each component is electrically connected, but the total mounting space becomes excessively large
Solution Approach 1:
The patent merges multiple separate connector devices into a single integrated circuit board structure. Multiple flexible connecting members are combined into one board, with all electrical connections routed through integrated vias and traces, reducing the total mounting area while maintaining reliable electrical connections through the unified structure.
Solution Approach 2:
The patent implements a nested arrangement where flexible connecting members are stacked in multiple layers, with lower layers positioned beneath upper layers. This nesting in the vertical dimension allows multiple camera components to be connected within a compact footprint, significantly reducing the required mounting area.
