Push-Button Pressure Balance Valve for Independent Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure balance valves in showers and bathtubs lack easy temperature control and decoupling of on/off function and temperature control, making it difficult to achieve desired temperature settings.
Innovation Solution
A push-and-turn pressure balance valve apparatus with a push button assembly that allows independent control of on/off function and temperature adjustment through separate press/release and rotation actions, respectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single handle is used to control on/off function, water volume, and temperature, then the device structure is simple, but temperature control precision deteriorates
Solution Approach 1:
The single handle control is segmented into two independent controls: a push button for on/off function and water volume, and a rotary dial for temperature control. This segmentation allows each control to be optimized for its specific function, improving temperature control precision while maintaining overall structural simplicity.
2Device complexity
If a single handle controls on/off function and temperature, then the device structure is simple, but ease of operation deteriorates
Solution Approach 1:
The control functions are segmented into separate operations: pushing the button for on/off control and rotating the dial for temperature adjustment. This segmentation makes each operation intuitive and easy to perform, improving ease of operation while keeping the device structure relatively simple.
Solution Approach 2:
The control mechanism uses dynamic actions (pushing and rotating) that are naturally intuitive for users. The push button provides clear tactile feedback for on/off status, and the rotary dial allows continuous temperature adjustment, both enhancing ease of operation.
3Device complexity
If on/off function and temperature control are integrated, then the device structure is simple, but adaptability deteriorates
Solution Approach 1:
The integrated control is segmented into independent on/off button control and temperature dial control. This allows users to adjust temperature without changing flow rate, or control flow rate without affecting temperature settings, thereby improving adaptability and control versatility while maintaining simple device structure.
Solution Approach 2:
The push button assembly serves multiple functions: it controls on/off status and water volume through pushing, while the rotary dial independently controls temperature. This multi-functionality design improves adaptability by allowing independent adjustment of different parameters without complicating the overall valve structure.
