Group-Controlled Dip Switch Sealing for Waterproof Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sensors lack an effective waterproof structure, rendering them unable to operate properly in humid environments, and they also lack the group-controlled function, limiting their applications.
Innovation Solution
A waterproof sensor with a group-controlled dip switch is designed, featuring a housing with a switch hole, a waterproof ring, and a switch hole sealing pad with multiple sealing rings, providing a double-layer waterproof structure and enabling group-controlled functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensors are placed in humid environments, then the sensors can be used in more applications, but the circuit boards of the sensors are prone to damage upon contact with water
Solution Approach 1:
The patent divides the sealing structure into multiple segments: a waterproof ring with first and second protruding rings forming separate grooves, and a sealing pad with corresponding first and second sealing rings. This segmented approach creates multiple independent waterproof barriers, allowing the sensor to maintain reliability in humid environments while expanding application scope.
Solution Approach 2:
The patent implements preventive waterproofing by placing the waterproof ring and sealing pad before water can reach the circuit board. The double-layer waterproof structure acts as a pre-established protective barrier, cushioning the internal components from water damage before exposure occurs, thus ensuring reliability in humid environments.
2Reliability
If a waterproof structure is added to the sensor, then the sensor can operate in humid environments, but the device complexity increases
Solution Approach 1:
The patent merges the waterproof ring and sealing pad into an integrated assembly that works together as a unified waterproof system. The waterproof ring with its protruding rings is combined with the sealing pad featuring corresponding sealing rings, creating a cohesive structure that provides enhanced waterproof protection without requiring entirely separate components, thus managing complexity while improving reliability.
