Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional rigid lampshade structure is used, then the lampshade provides good structural stability and light diffusion, but the packaging volume is large leading to high transportation costs
Solution Approach 1:
The lampshade is divided into multiple support members (first support member and second support member) that can be segmented and folded relative to each other. The support members are connected through joint members that allow folding, enabling the lampshade to be disassembled into smaller components for compact packaging while maintaining structural stability when assembled.
Solution Approach 2:
The lampshade structure transitions from a static rigid form to a dynamic foldable structure. The joint members enable the support members to rotate and fold, allowing the lampshade to change its configuration between expanded (for use) and collapsed (for storage and transportation) states, thereby reducing packaging volume without compromising structural integrity during use.
2Ease of manufacture
If a complex assembly structure is used, then the lampshade achieves stable structure, but the assembly process becomes difficult and time-consuming
Solution Approach 1:
The lampshade is segmented into modular components (support members, joint members, cloth covering) that can be independently manufactured and then easily assembled. The joint members are designed as separate components that connect the support members through simple insertion and rotation actions, eliminating the need for complex assembly tools or procedures while ensuring structural stability through proper mechanical connection.
3Adaptability or versatility
If the lampshade is designed as a single rigid structure, then it provides good light diffusion, but it creates difficulties in transportation and increases costs
Solution Approach 1:
The lampshade employs dynamic joint members that allow the support members to rotate and fold, enabling the structure to adapt between expanded and collapsed states. This dynamic capability allows the same structure to serve multiple purposes: providing adequate volume for light diffusion when assembled, and minimizing packaging volume during transportation, thereby increasing overall adaptability and versatility.
Solution Approach 2:
The foldable design makes the lampshade universally applicable to different lamp types and installation scenarios. The same lampshade can be compactly packaged for economical transportation and then easily assembled for use, allowing it to be deployed in various locations and applications without requiring specialized rigid structures, thus achieving multi-functionality and broader adaptability.
