Valve Puller Fulcrum Support for Rim-Safe Valve Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for installing and removing tire air valves often result in damage to the air valve or the rim due to the use of pliers, which is inefficient and prone to causing harm.
Innovation Solution
A valve puller with a main body, valve assembly, and support mechanism that includes adjustable support bodies and a resistance mechanism to facilitate safe and efficient pulling of the valve head, utilizing a fulcrum mechanism to prevent damage and provide stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pliers are used to pull the air valve, then the pulling operation can be performed, but damage to the air valve or rim occurs easily
Solution Approach 1:
The patent introduces a specialized pulling tool as an intermediary between the operator and the air valve. This tool includes a clamping mechanism that securely grips the valve stem and a pulling mechanism that applies force through a fulcrum system, rather than directly pulling the valve head with pliers. The intermediary tool distributes the pulling force appropriately and provides controlled engagement, preventing damage to the air valve and rim while enabling the pulling operation.
Solution Approach 2:
The pulling tool is divided into functional segments: a clamping portion that engages with the valve stem, a pulling mechanism with fulcrum, and a support mechanism. This segmentation allows each component to perform its specific function - the clamping portion secures the valve without damaging it, the fulcrum provides leverage, and the support mechanism stabilizes the operation, collectively preventing damage while enabling efficient pulling.
2Object-affected harmful factors
If a specialized pulling tool is designed, then damage to air valve and rim is prevented, but device complexity increases
Solution Approach 1:
The pulling tool is designed with multi-functionality to justify its complexity. It can handle different valve types and sizes through adjustable clamping mechanisms, serve as both a pulling tool and a support mechanism during installation, and potentially function as a removal tool. This universality consolidates multiple operations into one tool, making the increased complexity worthwhile by preventing damage across various应用场景.
Solution Approach 2:
The patent merges the clamping function, pulling function, and support function into a single integrated tool rather than using separate tools for each function. The fulcrum mechanism is combined with the pulling mechanism, and the support structure is integrated into the tool body. This merging reduces the number of separate components needed and simplifies the overall system while maintaining the damage prevention capabilities.
