Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional outdoor monitors use rotating shafts to connect housings, then mobility is improved, but water or water vapor can easily enter through gaps between rotating shafts, causing damage to circuit boards
Solution Approach 1:
A sealing member is introduced as an intermediary component between the rotating shaft and housing. The sealing member includes a main body portion disposed in the gap between the rotating shaft and housing, and a tube-shaped portion that covers the electronic cable. This intermediary structure prevents water and water vapor from entering through the gap while allowing the rotating shaft to maintain its rotational function, thus resolving the contradiction between mobility and waterproofing.
Solution Approach 2:
The sealing member employs flexible sealing structures that can accommodate the rotational movement of the shaft while maintaining the seal. The tube-shaped portion covering the electronic cable acts as a flexible protective barrier, allowing the cable to move with the rotating shaft while preventing water ingress. This flexible sealing approach enables both mobility and reliable waterproofing.
2Reliability
If conventional outdoor monitors use glue to bond joints of components for waterproofing, then waterproof properties are improved, but disassembly, assembly, and rework become difficult
Solution Approach 1:
The sealing solution is divided into separate modular components: a main body portion and a tube-shaped portion. These segmented sealing members can be independently installed, removed, and replaced without requiring the entire assembly to be disassembled. This segmentation eliminates the need for permanent gluing while maintaining effective waterproofing, thus improving reworkability while preserving waterproofing reliability.
Solution Approach 2:
The sealing member acts as a removable intermediary component that provides waterproofing without permanent bonding. Unlike glue that permanently bonds components, the sealing member can be installed and removed by simple mechanical means, allowing for easy disassembly, assembly, and rework while maintaining effective waterproof protection at the joints and cable penetrations.
3Adaptability or versatility
If electronic cables are routed through rotating assemblies, then connectivity between housings is maintained, but water can enter through the cable path
Solution Approach 1:
The tube-shaped portion of the sealing member functions as a flexible protective sheath that covers the electronic cable. This tube-shaped structure allows the cable to pass through the rotating assembly while maintaining connectivity between housings. Simultaneously, it forms a waterproof barrier that prevents water from entering through the cable path, thus resolving the contradiction between maintaining connectivity and preventing water ingress.
