Valve Assembly Depth Indication via Segmented Protective Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temperature control valves in bathrooms require cumbersome measurement and removal of protective covers for testing water leakage, leading to installation and maintenance inefficiencies due to the need for precise depth adjustments and potential measurement errors.
Innovation Solution
A valve assembly with a protective cover featuring multiple indication parts and a positioning plate that allows for quick and easy depth adjustment and fixing, facilitating installation, testing, and maintenance by indicating the correct depth and ensuring proper alignment with the finished wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the protective cover is made with a fixed depth higher than the basic wall to preserve depth, then the depth indication is improved, but the ease of operation deteriorates due to cumbersome measurement and removal processes
Solution Approach 1:
The protective cover is divided into a body portion and a front fence portion that can be separated. The front fence can be removed independently from the body, allowing easy access for water leakage testing without removing the entire protective cover. This segmentation resolves the contradiction by maintaining the depth-indicating front fence while enabling easy operation for maintenance.
Solution Approach 2:
The front fence is extracted as a separate removable component from the protective cover body. This allows the front fence with depth indication markings to remain on the wall for measurement guidance, while the body can be easily removed for testing and maintenance operations, thus improving both measurement precision and ease of operation.
2Reliability
If the protective cover is removed and reconnected multiple times for water leakage testing, then the testing function is improved, but the loss of time increases due to repeated screwing and unscrewing operations
Solution Approach 1:
The protective cover is segmented into a body and a detachable front fence. For water leakage testing, only the front fence needs to be removed, not the entire protective cover. This reduces the time required for testing while maintaining the ability to perform comprehensive water leakage tests, thus improving reliability without excessive time loss.
Solution Approach 2:
The front fence is designed to be preliminarily detachable from the body through a simple locking mechanism rather than requiring complete unscrewing. This preliminary action allows quick removal for testing and quick reattachment, reducing the time penalty associated with repeated testing operations while maintaining testing reliability.
3Manufacturing precision
If the depth of the protective cover is adjusted by measurement tools during installation, then the manufacturing precision is improved, but the device complexity increases due to the need for precise measurement and adjustment
Solution Approach 1:
The depth indication function is extracted from the main body of the protective cover and concentrated in the removable front fence. This allows the depth indication markings to be clearly visible and easily referenced during installation, improving manufacturing precision without adding complexity to the overall device. The front fence serves as a dedicated depth reference component.
Solution Approach 2:
The front fence incorporates self-service depth indication markings that automatically align with the wall surface during installation. These markings provide visual guidance for the correct installation depth without requiring external measurement tools or complex adjustment procedures, thus improving precision while reducing device complexity.

AI summary
A valve assembly capable of indicating a depth contains: a body and a protective cover. The body includes a holder. The protective cover is connected with the holder of the body, and the protective cover includes a fitting portion configured to fit with the holder, a peripheral portion surrounding the fitting portion, and at least one connection portion configured to connect with the fitting portion and the peripheral portion. The peripheral portion has an external fence, a front fence, a marking portion formed on at least one side of the peripheral portion, and multiple indication parts arranged on the marking portion and configured to denote depths among the multiple indication pails and the front fence respectively.
