Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light is transmitted via a fiber round bar, then the LED lamp structure is compact, but the transmitted light is not bright and is weak when seen from a distance
Solution Approach 1:
The patent extracts the light transmission function from the fiber round bar and replaces it with a reflective plate that directly reflects LED light. This eliminates the need for complex fiber optic structures while achieving brighter, more visible light transmission through the roller blind blind leaves.
Solution Approach 2:
The patent introduces a reflective plate as an intermediary element between the LED light source and the blind leaves. This reflective plate mediates the light transmission by reflecting LED light onto the blind leaves, achieving bright light transmission without requiring complex fiber optic structures.
2Strength
If upper and lower parts of aluminum profile are connected only by one position in the middle, then the structure is simple, but the connection strength is not enough to safely add accessories
Solution Approach 1:
The patent segments the connection structure by adding multiple connection positions (first connection position and second connection position) between upper and lower aluminum profiles. This segmentation distributes the load and provides multiple attachment points for accessories, significantly improving connection strength while maintaining structural simplicity.
3Reliability
If the aluminum profile opening is designed for basic function, then manufacturing is easy, but the opening deforms easily affecting roller blind operation
Solution Approach 1:
The patent applies preliminary action by pre-reinforcing the aluminum profile opening structure with加强 ribs before the deformation issue occurs. This reinforcement is built into the manufacturing process, preventing deformation during use while not significantly complicating the manufacturing process.
4Object-affected harmful factors
If LED lamp irradiates directly forward, then the lighting function is simple, but direct light irradiates driver eyes causing discomfort and safety hazard
Solution Approach 1:
The patent applies asymmetry by deflecting the LED lamp irradiation direction from direct forward to an angled direction. The LED lamp is positioned and oriented asymmetrically relative to the front, causing light to illuminate the interior space without directly entering the driver's eyes, thus eliminating the safety hazard while maintaining simple lighting structure.
