Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the light cover is made smaller to meet miniaturization requirements, then the mobile terminal size is reduced, but the energy loss of infrared light signal increases and remote control capability weakens
Solution Approach 1:
The patent applies a concave curved surface (specifically a spherical cap surface) on the light cover to focus and concentrate the infrared light. This curvature design allows the light to be efficiently directed through the reduced-size light cover, maintaining transmission effectiveness despite the smaller dimensions. The curved surface refracts and concentrates the infrared rays, preventing energy loss that would occur in a flat or improperly shaped cover.
2Ease of manufacture
If the light cover structure is simplified, then the manufacturing process is easier, but the infrared light transmission efficiency decreases
Solution Approach 1:
The patent merges the light cover and positioning station into a single integrated component. The light cover is formed as one piece with the positioning station, eliminating the need for separate assembly steps while maintaining the optical focusing function. This integration simplifies the manufacturing process compared to multi-component designs, while the embedded concave curved surface ensures proper light concentration and transmission efficiency.
