Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If additional lighting devices are used for work in cloudy weather or at night, then working conditions are improved, but device complexity and ease of operation deteriorate due to the need for separate lighting equipment
Solution Approach 1:
The patent integrates the lighting device directly into the repair tool housing, combining two previously separate functions (repair tool operation and illumination) into a single integrated unit. This eliminates the need for separate lighting equipment while providing improved working conditions during cloudy weather or nighttime operations.
2Illumination intensity
If lighting devices are installed in power tools, then illumination is provided, but focusing of light deteriorates in narrow spaces
Solution Approach 1:
The patent employs multiple LED light sources strategically positioned within the housing, with each LED equipped with its own lens. This local optimization of light emission points and individual lens focusing allows the system to provide adequate illumination while maintaining focused light beams that can penetrate into narrow work spaces effectively.
3Illumination intensity
If lighting devices are installed in tools, then working conditions are improved, but reliability deteriorates due to vulnerability to vibration and loosening
Solution Approach 1:
The patent incorporates a securing mechanism with threaded holes in the housing that allows the lighting device assembly to be firmly fastened before operation begins. This preliminary securing action prevents vibration-induced loosening and maintains reliable illumination throughout the repair work, even in high-vibration environments.
4Illumination intensity
If lighting devices are installed in tools, then illumination is provided, but ease of repair deteriorates because the entire circuit must be inspected and repaired if the device breaks
Solution Approach 1:
The lighting device is designed as a modular assembly that can be separated from the main tool housing. The lighting component with its LED sources and lenses forms an independent unit that can be removed and replaced without requiring disassembly or inspection of the entire tool circuit, significantly simplifying repair operations.
