Valve Tool Spring Compression Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in disassembling multi-port valves, particularly those with springs, due to the stiffness of the springs, which requires stabilization and compression for service and replacement of components.
Innovation Solution
A valve tool with an upper and lower support portion, a press to compress the spring between the rotor and lid, and adjustable posts to fit the valve, allowing for the removal and installation of the handle and other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the spring is compressed to remove the handle pin, then the valve can be disassembled for service, but the operation becomes difficult and requires stabilization of the valve
Solution Approach 1:
The patent introduces a compression tool as an intermediary device between the user and the valve spring. The tool includes a compression arm that applies force to compress the spring, and a stabilization mechanism that holds the valve body steady during the operation. This intermediary tool eliminates the need for manual stabilization and spring compression, directly resolving the technical contradiction by making the disassembly process easier while eliminating the operational difficulty.
Solution Approach 2:
The compression tool is divided into distinct functional segments: a stabilization component that secures the valve body, a compression arm that applies force to the spring, and a release mechanism. This segmentation allows each component to perform its specific function efficiently, with the stabilization portion handling the valve security and the compression portion handling the spring compression, thereby resolving the contradiction between ease of repair and ease of operation.
2Stability of the object's composition
If the valve includes a stiff spring for internal components, then the valve structure is stable, but the spring compression required for handle removal becomes difficult
Solution Approach 1:
The compression tool acts as an intermediary that bridges the need for structural stability and the need for easy operation. The tool's stabilization component maintains the valve's structural integrity during the compression process, while the compression arm provides the necessary force to compress the stiff spring. This intermediary device resolves the contradiction by allowing the spring to remain stiff for structural stability while making compression easy through mechanical advantage.
Solution Approach 2:
The compression tool incorporates dynamic elements including a movable compression arm that can apply variable force, and a release mechanism that allows controlled spring expansion. The tool transitions from a stabilized state during compression to a released state after handle removal, allowing the system to adapt between maintaining structural stability and enabling easy operation throughout the disassembly process.
