Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional fixed design lamps are used, then structural stability is maintained, but device complexity increases and volume becomes large
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed rigid structures with flexible components. The flexible lamp sheet can dynamically change its shape and configuration, allowing the lamp to adapt between different lighting patterns without requiring multiple fixed structural designs. This dynamic flexibility reduces overall device complexity while maintaining structural stability through the inherent properties of the flexible material.
Solution Approach 2:
The flexible lamp sheet serves multiple functions simultaneously - it acts as both the structural support and the light-emitting element. By integrating these functions into a single universal component, the patent eliminates the need for separate rigid structural frames and light sources, thereby reducing device complexity and volume while maintaining stability through the flexible sheet's unified design.
2Adaptability or versatility
If multiple fixed angle components are used to achieve different light angles, then lighting versatility is improved, but device complexity and volume increase
Solution Approach 1:
The flexible lamp sheet enables dynamic adjustment of light angles by physically bending or folding to different configurations. This single dynamic component replaces what would traditionally require multiple fixed-angle reflectors or directional light sources, achieving lighting versatility while significantly reducing structural complexity.
Solution Approach 2:
The patent changes the physical parameters of the lamp sheet - its curvature, folding angle, and spatial orientation - to achieve different light emission angles. By varying these parameters rather than using multiple fixed components, the system achieves adaptability with simpler structure.
3Volume of moving object
If traditional rigid lamp structures are used, then manufacturing precision is maintained, but volume becomes large
Solution Approach 1:
The patent employs a flexible lamp sheet that can be precisely manufactured in a flat state and then deformed into various three-dimensional configurations during use. This approach allows for precise manufacturing of the base material while achieving complex spatial forms through flexible deformation, significantly reducing volume compared to rigid pre-formed structures.
Solution Approach 2:
The flexible lamp sheet transitions from a two-dimensional flat state during manufacturing to various three-dimensional configurations during operation. This dimensional transformation allows for compact storage and precise manufacturing in the flat state, while achieving the required spatial complexity and volume reduction through controlled deformation in use.
