Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional dampers or friction-based connections are used among the bottom, support part, and expansion and retraction structure, then the bracket can achieve angle and height adjustment, but the support becomes unstable after repeated use and the structure becomes complex
Solution Approach 1:
The patent replaces the traditional mechanical friction-based connection system with a cam mechanism that uses geometric shape interaction. The cam profile converts rotational motion into controlled linear displacement, providing stable positioning through precise geometric constraints rather than friction. This substitution eliminates the instability issue while simplifying the overall mechanical structure.
Solution Approach 2:
The patent changes the connection mechanism from friction-dependent to geometry-dependent by designing specific cam profiles. The cam mechanism transforms the adjustment parameter control from continuous friction-based holding to discrete position-based locking through the cam follower interaction, improving reliability while maintaining adjustability.
2Ease of operation
If traditional dampers or friction-based connections are used among the bottom, support part, and expansion and retraction structure, then the bracket can achieve angle and height adjustment, but the structure becomes complex and assembly difficulty increases
Solution Approach 1:
The patent replaces the traditional mechanical friction-based connection system with a cam mechanism that uses geometric shape interaction. The cam profile converts rotational motion into controlled linear displacement, providing stable positioning through precise geometric constraints rather than friction. This substitution eliminates the instability issue while simplifying the overall mechanical structure.
Solution Approach 2:
The patent merges the adjustment and locking functions into a single cam mechanism. The cam profile simultaneously provides the adjustment range and the positioning stability, eliminating the need for separate dampers, friction elements, and locking mechanisms. This consolidation reduces structural complexity while maintaining full adjustability.
3Ease of operation
If traditional dampers or friction-based connections are used among the bottom, support part, and expansion and retraction structure, then the bracket can achieve angle and height adjustment, but the production cost is increased
Solution Approach 1:
The patent merges the adjustment and locking functions into a single cam mechanism. The cam profile simultaneously provides the adjustment range and the positioning stability, eliminating the need for separate dampers, friction elements, and locking mechanisms. This consolidation reduces structural complexity while maintaining full adjustability.
Solution Approach 2:
The cam mechanism can be manufactured as a single molded or machined component, replacing multiple precision-machined parts like dampers and friction elements. This single-component approach reduces manufacturing steps, assembly operations, and quality control complexity, thereby lowering production costs.
