Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional rotary night lamp structures are used, then the lamp can rotate and provide lighting, but the assembly process becomes complex and cost increases
Solution Approach 1:
The patent combines the rotary connector, power plug, and holder into an integrated rotary plug holder assembly. The connector body integrates the rotary mechanism, first power plug, and second power plug into a single unified structure, eliminating the need for separate assembly of multiple components and simplifying the overall assembly process while maintaining the 360° rotation function.
Solution Approach 2:
The rotary plug holder serves multiple functions simultaneously: it provides electrical connection through the power plugs, enables 360° rotation through the rotary connector mechanism, and incorporates location flanges for precise positioning. This multi-functionality reduces the need for additional separate components, thereby simplifying assembly and reducing cost.
2Ease of operation
If conventional rotary night lamp structures are used, then the lamp can rotate and provide lighting, but the cost increases due to high metal slice usage
Solution Approach 1:
The patent extracts and eliminates unnecessary metal slices from the conventional design. By redesigning the electrical connection system to use the integrated rotary plug holder with embedded power plugs, the design removes redundant metal connection pieces, thereby reducing material usage and cost while maintaining electrical connectivity and rotation functionality.
Solution Approach 2:
The patent employs cost-effective materials and design elements, such as using location flanges made from molded plastic or lightweight materials instead of expensive metal components. The location flanges provide sufficient positioning functionality without requiring durable, expensive materials, thus reducing overall component cost.
3Adaptability or versatility
If conventional night lamp structures are used, then basic lighting is provided, but adaptability to different interior decoration requirements is limited
Solution Approach 1:
The patent incorporates a 360° rotary connector that allows the holder to rotate freely and be positioned at any angle. This dynamic positioning capability enables the lamp to adapt to different interior decoration requirements and lighting directions without requiring multiple fixed-angle models, thereby enhancing versatility while maintaining a simple single-structure design.
Solution Approach 2:
The location flanges are designed with asymmetric positioning features that allow the rotary plug holder to be securely positioned at various angles. The flanges have specific engagement surfaces that work with corresponding slots or guides, enabling precise angular positioning while maintaining structural simplicity and avoiding complex adjustment mechanisms.
