Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a circuit board is additionally arranged on a common button switch to realize a power-off protection function, then the power-off protection function is achieved, but the internal space of the electric tool needs to be enlarged, the structure of an existing electric tool product needs to be adjusted greatly, and the cost is high
Solution Approach 1:
The patent integrates the power-off protection function directly into the button switch assembly by incorporating a capacitor and control circuitry within the switch housing. This merging of functions eliminates the need for separate protection circuits in the electric tool, maintaining compact overall dimensions while achieving the required safety function.
Solution Approach 2:
The button switch is designed to perform multiple functions: primary switching operation, power-off protection, and potential reset capabilities. By making the switch multi-functional, the patent eliminates the need for additional dedicated protection components, thereby avoiding increased internal space requirements in the electric tool.
2Reliability
If a circuit board is additionally arranged on a common button switch to realize a power-off protection function, then the power-off protection function is achieved, but the structure of an existing electric tool product needs to be adjusted greatly, and the cost is high
Solution Approach 1:
The protection function is merged into the existing button switch structure rather than being implemented as a separate circuit board addition. This integration approach maintains the simplicity of the overall device structure and avoids the need for significant structural adjustments to existing electric tool products.
3Reliability
If a multi-layer structure is used in the button switch, then the power-off protection function can be realized, but glue needs to be smeared repeatedly to bond the multi-layer structure in the production process, the production process is complex, and the production efficiency is low
Solution Approach 1:
The button switch is designed with a segmented modular structure where functional components (switch mechanism, capacitor, contacts) are arranged in distinct but integrated sections. This segmentation allows for straightforward assembly without requiring complex multi-layer bonding processes, thereby maintaining high production efficiency while achieving the protection function.
