Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wall lamp is installed at a fixed angle, then the installation is simple, but the lighting distance and range are single and cannot meet different lighting needs
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed angle installation into an adjustable angle mechanism. The heat dissipation component is connected to the lamp body shell through a limit rotating member that can rotate within a limited range, allowing the lighting angle to be dynamically adjusted while maintaining structural stability. This enables the lamp to adapt to different lighting needs without requiring a completely complex adjustment mechanism.
2Measurement precision
If existing lamps have angle adjustment functions by changing external structure, then angle adjustment is possible, but the adjustment accuracy is poor and affects the appearance
Solution Approach 1:
The patent applies segmentation by dividing the angle adjustment function into separate components: the heat dissipation component, the limit rotating member, and the gear member. Each component has a specific function - the limit rotating member provides precise angular positioning through its toothed structure, while the gear member engages with it to lock the angle. This segmented approach achieves high adjustment accuracy without requiring complex modifications to the overall external structure, preserving the lamp's appearance.
3Adaptability or versatility
If the heat dissipation component is firmly fixed, then the connection is stable, but the angle cannot be adjusted
Solution Approach 1:
The patent resolves this contradiction by implementing a dynamic connection mechanism. The heat dissipation component is connected to the lamp body shell through a limit rotating member that can rotate within a limited range and then lock into position. This dynamic design allows the connection to be stable during normal operation (when locked) while enabling angle adjustment when needed (when rotated), thus achieving both adaptability and reliability.
Solution Approach 2:
The limit rotating member acts as an intermediary between the heat dissipation component and the lamp body shell. It provides a mechanical interface that allows controlled rotation and locking, mediating between the need for angle adjustment and the need for connection stability. The gear member further enhances this intermediary function by providing positive engagement to lock the angle in place.
