Temperature-Sensing Shower Drainage Structure for Automatic Cold Water Bypass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower equipment requires manual operation to discharge cold water, leading to inconvenience and potential drenching from cold water during the process, as the existing control-and-switching valve devices are complex and not user-friendly.
Innovation Solution
A cold water discharge structure with a housing containing a temperature sensing component and an elastic element that automatically diverts cold water through a drainage hole, preventing it from flowing through the outlet and switching to hot water output once the temperature rises, eliminating the need for manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a control-and-switching valve device is used to discharge cold water, then cold water can be discharged from the water outlet, but the structure becomes complex and manual operation is still required
Solution Approach 1:
The patent extracts the cold water discharge function from the main water outlet path by providing a separate drainage hole positioned away from the user area. This separates the cold water discharge function from the hot water delivery function, allowing independent operation without complex valve mechanisms.
Solution Approach 2:
The water discharge system is segmented into two independent paths: one through the water outlet for hot water and another through the drainage hole for cold water. This segmentation allows simple independent control of each function without requiring complex switching mechanisms.
2Ease of operation
If cold water is discharged through the original water outlet, then cold water can be discharged, but users may be drenched by cold water and convenience is reduced
Solution Approach 1:
The cold water discharge function is extracted from the main water outlet and relocated to a separate drainage hole positioned away from the user area. This physical separation ensures cold water does not contact the user while maintaining effective cold water discharge capability.
3Extent of automation
If manual operation is required to switch between cold water discharge and hot water output, then control is possible, but convenience and automation are reduced
Solution Approach 1:
The system achieves automatic temperature switching through self-service mechanisms: a temperature-sensitive element automatically closes the drainage hole when hot water arrives, and a float mechanism automatically opens it when cold water needs discharge. No manual intervention is required.
Solution Approach 2:
The patent implements feedback mechanisms where temperature-sensitive elements detect water temperature and automatically control the drainage hole closure. The float mechanism provides level feedback to control the opening/closing of the drainage hole based on water accumulation.
