Hinged Glue Tab Assembly for Durable Paintless Dent Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional paintless dent repair tools, particularly glue tab tools, are prone to breaking, deforming, or cracking due to their single unitary construction, requiring multiple tools for different sized dents and increasing the time and cost of the repair process.
Innovation Solution
A modular hinge tab assembly comprising a first and second hinge tab, a hinge lift, and a ball detention pin, allowing these components to rotate about the pin, with a lateral tension tab block for structural support, enabling reuse and customization for various dent sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional single unitary glue tab tools are used, then the tool has sufficient strength to pull dents, but the tool is prone to breaking, deforming, or cracking during use
Solution Approach 1:
The tool is divided into multiple separate components: a body portion, a neck portion, and a tab portion. These segments are connected through a hinge mechanism with a ball detention pin, allowing each part to function independently while maintaining overall structural integrity. This segmentation prevents stress concentration at single points, reducing the likelihood of breaking or cracking during use.
Solution Approach 2:
The hinge mechanism introduces dynamic movement capability to the traditionally static unitary structure. The neck portion can rotate relative to the body and tab portions through the ball detention pin hinge, allowing the tool to adapt to varying dent geometries and pull forces. This dynamic flexibility reduces stress on individual components while maintaining pulling strength.
2Ease of manufacture
If traditional glue tab tools with uniform neck diameter are used, then manufacturing is simplified, but the tools cannot be efficiently used for dents of various sizes
Solution Approach 1:
The tab portion is segmented into multiple interchangeable tabs of different sizes and shapes. Each tab can be attached to the neck portion as needed, allowing the same tool body to adapt to various dent sizes. The neck portion maintains a uniform diameter for manufacturing simplicity, while the interchangeable tabs provide the necessary versatility.
Solution Approach 2:
The tool body and neck portion serve as universal components that can work with multiple different tab sizes. The hinge mechanism with ball detention pin provides a standardized interface that accommodates various tab configurations, making the tool versatile for different dent scenarios while keeping the core structure simple to manufacture.
3Adaptability or versatility
If multiple traditional glue tab tools are used for different dent sizes, then adaptability is improved, but the number of tools and time required for repair increases
Solution Approach 1:
Multiple tab sizes and configurations are merged into a single tool system. The interchangeable tab mechanism allows one tool body to perform the function of what would traditionally require multiple separate tools. The hinge and ball detention pin system provides a unified interface for attaching different tabs, consolidating the toolset while maintaining versatility.
Solution Approach 2:
The tool body and neck portion are designed as universal components that can accommodate multiple different tab sizes and shapes. This multi-functionality allows a single tool to handle various dent sizes and geometries, reducing the total number of tools needed in the repair shop while maintaining comprehensive adaptability.
4Ease of operation
If traditional glue tab tools are used, then the pulling action is simple, but curved arcs or bumps are created requiring additional knock-down tools
Solution Approach 1:
The hinge mechanism allows the tab portion to rotate and pivot during the pulling operation, enabling the force to be applied more dynamically across the dent surface. This rotational capability helps distribute the pulling force more evenly, reducing the formation of curved arcs and bumps that would require additional knock-down tools.

AI summary
A paintless dent repair glue tab tool, system and method is disclosed. In general, the paintless dent repair glue tab tool is a hinge tab assembly having a first hinge tab, second hinge tab, hinge lift, and ball detention pin. The first hinge tab, second hinge tab and hinge lift each have rings connected thereto and for slidably engaging with and connecting to the ball detention pin. In use, the first hinge tab and the second hinge tab are positioned about a dent on the surface of a vehicle and are connected to the surface of the vehicle using glue. The hinge lift is then pulled upward by a separate paintless dent removal tool causing the first hinge tab and second hinge tab to rotate about the ball detention pin and pull up and out the dent on the surface of the vehicle.
