Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrically-controlled dimming mode is used to switch luminous angle, then lighting angle can be adjusted, but cost increases significantly
Solution Approach 1:
The light transmission panel is divided into multiple independent lens areas, each corresponding to specific LED beads. Each lens area can independently deflect light at different angles, allowing selective activation of different lens areas to achieve angle switching without complex electrical control systems.
Solution Approach 2:
The lenses are designed to automatically deflect light based on their geometric structure and optical properties. When LED beads are selectively activated, the lenses passively redirect light without requiring active control mechanisms, reducing system complexity and cost.
2Adaptability or versatility
If manual lens replacement is used to adjust luminous angle, then lighting angle can be changed, but operation becomes complex and time-consuming
Solution Approach 1:
The system enables dynamic switching between different lighting angles by electrically controlling which LED beads are activated, rather than requiring physical replacement of lenses. The controller can rapidly switch between different lens areas, providing flexible and easy angle adjustment.
3Adaptability or versatility
If multiple lenses are used to match a lamp panel, then lighting angle can be adjusted, but light source surface size increases resulting in bulky products
Solution Approach 1:
Each lens area is designed to serve multiple functions: it can deflect light at specific angles while also working with different LED bead configurations. The same lens structure handles both light transmission and angle control, eliminating the need for additional components and reducing overall surface area.
4Adaptability or versatility
If brightness of LED beads is controlled to adjust light emitting angle, then angle adjustment is achieved, but requires precise control mechanism
Solution Approach 1:
The system controls light emitting angles by changing the brightness parameter of LED beads through simple dimming control. The controller adjusts current to LED beads, and this parameter change automatically produces the desired angle adjustment through the optical properties of the lenses, avoiding complex control mechanisms.
