Solution Overview
Problem
Existing faucet temperature display devices are prone to short-circuiting due to moisture exposure and require professional installation, leading to increased labor costs and potential damage to the wall structure.
Innovation Solution
A sealed display device integrated into the faucet with a hydraulic power generation module and protection module, allowing for easy installation and removal, and preventing moisture ingress to prevent short-circuiting, comprising a sealing housing, circuit board, display module, temperature detection unit, and a protection module with a water-resistant lid and sealing ring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display device is externally attached to the faucet, then the temperature can be displayed, but the device is prone to short-circuiting due to moisture exposure
Solution Approach 1:
The display device is nested within the faucet body structure. The housing is received within the faucet, and the temperature detection unit extends into the water flow path. This nesting arrangement protects the electronic components from moisture exposure while enabling direct temperature measurement of the water.
Solution Approach 2:
A sealed housing acts as an intermediary barrier between the electronic components and the moisture environment. The housing includes a sealed cavity that receives the circuit board and display module, preventing moisture ingress while allowing the temperature detection unit to measure water temperature through a dedicated opening.
2Ease of operation
If the display device is externally mounted on the wall, then the temperature can be displayed, but professional installation is required causing wall damage
Solution Approach 1:
The display device is merged with the faucet assembly as an integrated unit. The housing is received within the faucet body, and components are combined into a single assembly that can be installed or removed as one unit. This eliminates the need for separate wall mounting and professional installation.
Solution Approach 2:
The display device is designed as a separable module that can be independently removed from the faucet. The housing can be detached from the faucet body, allowing users to replace the display device without affecting the faucet structure or requiring wall repairs.
3Reliability
If the temperature detection unit is fully enclosed in the housing, then protection from moisture is improved, but temperature detection accuracy may be affected
Solution Approach 1:
The housing provides sealed protection for electronic components in areas where moisture protection is critical, while the temperature detection unit has a localized opening or extension that exposes the sensing element to the water flow path. This creates different protection levels in different locations of the same device.
Solution Approach 2:
The housing structure acts as an intermediary that selectively allows temperature detection while blocking moisture. The housing includes a sealed cavity for electronics and a controlled opening that permits thermal contact with water while maintaining the moisture barrier.
