Wheel Weight Tool Hook Design for Scratch-Free Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tools for removing wheel weights are inadequate in handling various sizes and shapes, often causing scratches and pinching issues, and are not suitable for newer materials like steel and zinc, leading to increased rim damage and worker injuries.
Innovation Solution
A wheel weight tool with a handle connected to a hammer head and a hook design that includes a soft end for installation and a hard end with a second hook for removal, featuring a tip point, throat, and heel to securely engage and rotate wheel weights, accommodating different hole sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard wheel weight tools (hammers, pliers, screwdrivers) are used to install and remove wheel weights, then the wheel weight can be securely attached and removed, but the wheel weight coating and wheel surface chip or scratch during installation and removal
Solution Approach 1:
The patent introduces a specialized wheel weight removal tool with a hook that acts as an intermediary between the wheel weight clip and the wheel. The hook engages with the clip's hole and allows removal through rotational motion rather than direct prying or pinching forces that cause damage. This intermediary mechanism transfers the removal force in a controlled manner that protects both the wheel weight coating and wheel surface from chipping and scratching while still achieving reliable removal.
2Adaptability or versatility
If traditional plier-type removal tools are used, then removal can be achieved for older wheel weight designs, but they cannot adequately handle newer materials (steel, zinc) and various hole configurations
Solution Approach 1:
The patent designs a universal wheel weight removal tool with a hook that can accommodate multiple hole configurations and materials. The hook's geometry and the associated rotational removal mechanism work effectively with traditional lead weights, newer steel and zinc weights, and various hole placements (center, offset, different diameters). This multi-functional design eliminates the need for different tools for different weight types, providing ease of operation across all modern wheel weight variations.
3Force
If pliers-type tools are used for wheel weight removal, then removal force can be applied, but worker injuries occur due to pinching and high cost of workman's comp claims
Solution Approach 1:
The patent replaces the traditional plier-type mechanical system with a hook-based rotational removal system. Instead of using pinching and squeezing forces that concentrate stress on the worker's fingers and hands, the new system uses a hook that engages the clip hole and applies rotational force. This substitution of the mechanical mechanism distributes the removal force more safely, eliminating the pinching action that causes injuries while still providing sufficient removal force.
4Reliability
If hammering is used to install wheel weights, then secure attachment is achieved, but the coated wheel weight surface chips or scratches
Solution Approach 1:
The patent uses a specialized installation tool with a soft or rubberized hammer head as an intermediary between the installer's hand and the wheel weight. This soft hammer head delivers the necessary impact force to secure the wheel weight attachment while absorbing the shock and preventing direct metal-on-metal contact that would chip or scratch the coated surface. The intermediary soft material protects the delicate coating during the installation process.
