Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If multiple separate parts (reflector, lens, light source, control circuit board, heat sink) are assembled to form the light, then the light can be repaired or maintained, but the assembly complexity increases and reliability decreases
Solution Approach 1:
The patent integrates the reflector, lens, light source, control circuit board, and heat sink into a single integrated light module that is pre-assembled and calibrated at the factory. This merging of components eliminates the need for users to assemble multiple separate parts, reducing assembly complexity while maintaining the ability to replace the entire module for repair and maintenance.
2Ease of repair
If the light source is mounted with multiple separate components, then the light can be maintained and replaced, but alignment and thermal coupling require precise assembly steps that may lead to reliability issues
Solution Approach 1:
The integrated light module ensures that the light source, heat sink, and optical components are pre-aligned and thermally coupled during manufacturing with precise control. This eliminates the need for users to perform precise alignment and thermal coupling during maintenance, as the entire module is replaced as a single unit, ensuring consistent performance and reliability.
3Device complexity
If conventional lights are designed with fixed light direction, then the structure is simple, but the flexibility in directing light is limited
Solution Approach 1:
The patent incorporates a rotatable clip mechanism that allows the user to dynamically adjust the direction of the light beam. The clip can rotate to different positions, enabling the light to be directed at various angles while maintaining a relatively simple overall structure. This dynamic adjustment capability provides directional flexibility without significantly increasing structural complexity.
4Device complexity
If the light is designed for hand-held use only, then the structure is simple, but the ease of use in various orientations and attachment scenarios is limited
Solution Approach 1:
The patent designs the light with multiple attachment options, including a rotatable clip for clipping to pockets or belts, and a hanger for suspending the light from hooks or other supports. This multi-functionality allows the light to be used in various orientations and attachment scenarios, enhancing usability flexibility while adding only moderate structural complexity.
