Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a bump and indentation structure with exposed switch element is used, then the mode-switching device can be operated, but the procedures of forming the bump and indentation become complicated and not cost-effective
Solution Approach 1:
The patent extracts the switch element from its traditional exposed position and integrates it into the foldable plate structure itself. The foldable plate's hinge connection directly engages with the control circuit board, eliminating the need for separate bumps and indentation structures. This integration simplifies the manufacturing process while maintaining the switching functionality.
Solution Approach 2:
The patent merges the switch element function into the foldable plate structure. The hinge connection of the foldable plate serves dual purposes: providing the mechanical folding action and simultaneously actuating the switch element on the control circuit board. This consolidation reduces the number of separate components and simplifies the overall structure.
2Reliability
If the switch element is exposed outside the indentation to ensure effective depression, then the mode switching can be actuated, but electrostatic discharge and electro-magnetic interference problems are generated
Solution Approach 1:
The patent uses the foldable plate as a flexible mechanical element that encapsulates the switching mechanism. The foldable plate's hinge connection provides a protected pathway for actuating the switch element, shielding it from direct exposure to the environment. This flexible structure maintains reliable switching while reducing susceptibility to electrostatic discharge and electromagnetic interference.
3Ease of manufacture
If the mode-switching device is made of plastic material, then the manufacturing is simplified, but the device is readily raised up if the weight thereof is not sufficient
Solution Approach 1:
The patent employs a spring element as a counterweight mechanism to balance the foldable plate. The spring provides an opposing force that prevents the lightweight plastic foldable plate from being easily raised or displaced. This allows the use of lightweight plastic material while maintaining position stability during operation.
4Ease of manufacture
If a gap between the bump and the switch element is present, then the assembly is easier to manufacture, but the stability and reliability of switching the operating modes is impaired
Solution Approach 1:
The patent designs the foldable plate's hinge connection to self-align with the switch element on the control circuit board. The geometric configuration of the hinge and switch element ensures automatic positioning during assembly, eliminating the need for precise manual adjustment. This self-aligning mechanism maintains reliable switching stability while simplifying the assembly process.
