Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable glands are used to provide waterproof and dustproof protection, then protection reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses a waterproof film (220) that flexes and deforms to seal around the cable (200) when tension is applied to the pull ring (210). This flexible film approach replaces complex rigid cable gland structures, achieving waterproof protection through a simple, adaptable membrane that conformally seals the cable entry point.
Solution Approach 2:
The patent extracts the essential waterproofing function from complex cable gland assemblies and implements it through a separate, simple pull ring (210) and waterproof film (220) system. The pull ring is detached from traditional cable gland housing, allowing independent installation of the waterproofing mechanism without requiring complex integrated structures.
2Reliability
If conventional cable glands are used to ensure waterproof protection, then reliability is improved, but ease of operation deteriorates due to difficult assembly and disassembly
Solution Approach 1:
The waterproof system transitions from a static rigid seal to a dynamic flexible seal. The waterproof film (220) and pull ring (210) system allows movement and deformation during installation and removal, enabling users to easily assemble by pulling the ring and disassemble by releasing tension, while maintaining a reliable seal when installed.
Solution Approach 2:
The waterproofing function is segmented into independent components: the pull ring (210) for installation/removal operation and the waterproof film (220) for sealing. This segmentation allows the film to remain sealed during use while enabling simple manual installation and disassembly without requiring complex tools or procedures.
3Reliability
If conventional cable glands are used to provide waterproof protection, then reliability is improved, but cost increases
Solution Approach 1:
The patent replaces expensive, complex cable gland assemblies with inexpensive components: a simple pull ring (210) and a flexible waterproof film (220). These components can be easily manufactured from common materials and are designed to be cost-effective, providing reliable waterproof protection without the high cost of traditional cable glands.
4Ease of manufacture
If a simple waterproof structure is used to reduce complexity and cost, then ease of manufacture is improved, but adaptability to different cable types deteriorates
Solution Approach 1:
The flexible waterproof film (220) naturally adapts to different cable diameters and shapes through elastic deformation. When the pull ring is pulled, the film stretches and conforms to the specific cable geometry, providing an effective seal regardless of cable type. This flexibility eliminates the need for multiple specialized fittings for different cable sizes.
Solution Approach 2:
The waterproof system achieves adaptability through parameter changes in the flexible film's physical state. The film transitions from a relaxed state to a stretched sealed state when tension is applied to the pull ring, allowing it to accommodate various cable dimensions and maintain an effective waterproof barrier across different cable types.
