Panel Remover with Recessed Bend and Soft Fulcrum Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel removal tools often damage neighboring components due to lack of leverage and inadequate protection at pivot points, leading to scratching or marring of surfaces.
Innovation Solution
A panel removal tool with a bend portion positioned behind the fulcrum for added leverage, featuring a cover made of a softer material than the rest of the tool to prevent damage, such as dipped polymer, which helps in maintaining surface integrity during panel lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wire-shaped prying instrument is used to remove panels, then the panel can be pried open, but the instrument rubs against the panel at the bend point and destroys or scratches the surface
Solution Approach 1:
The patent applies a soft coating specifically at the fulcrum point where the bend contacts the panel surface. This localized application of different material properties (soft coating vs. hard tool body) protects the surface at the critical contact point while maintaining the overall structural integrity and functionality of the tool.
Solution Approach 2:
The soft coating acts as an intermediary layer between the hard tool body and the panel surface. This intermediate layer prevents direct contact between the hard metal tool and the panel surface, eliminating scratching while still allowing the tool to function as a lever.
2Object-affected harmful factors
If a sleeve is added to cover the pry point to prevent scratching, then surface protection is improved, but the pivot point lacks appropriate leverage for lifting certain panels
Solution Approach 1:
The patent positions the soft coating specifically at the fulcrum point where leverage is applied, allowing the bend to extend behind the fulcrum for increased mechanical advantage. The localized soft coating provides surface protection exactly where needed without compromising the lever arm length or pivot point positioning.
Solution Approach 2:
The patent extends the tool's bend behind the fulcrum point, utilizing the spatial dimension to increase the lever arm length. This dimensional adjustment provides greater mechanical advantage and leverage for lifting panels while the soft coating at the fulcrum maintains surface protection.
3Object-affected harmful factors
If nylon or soft material instruments are used, then surface damage is reduced, but the instruments are weak and bend easily, lacking rigidity for higher load applications
Solution Approach 1:
The patent creates a composite structure combining a hard tool body (steel or aluminum) for strength and rigidity with a soft coating material at the fulcrum point for surface protection. This composite approach allows the tool to maintain structural integrity for high-load applications while preventing surface damage through the softer coating layer.
Solution Approach 2:
The patent applies the soft coating material only at the specific location where surface contact occurs (the fulcrum point), while the rest of the tool maintains its hard, rigid material properties. This localized differentiation allows the tool to be both strong for high-load applications and protective of surfaces where contact occurs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool effectively provides additional leverage for removing panels while preventing scratches and damage by using a softer material cover at the fulcrum, enhancing the tool's ability to handle higher load applications without compromising surface integrity.
Implementation Method 1
A cover is provided that covers a fulcrum of the bend and is composed of a cover material softer than a bend material of the bend
Implementation Method 2
a bend extending from the base and being offset from the longitudinal axis of the base, and a pry extending form the bend and adapted to be disposed underneath an object to be lifted

AI summary
Disclosed is a panel removing tool having a bend portion that is located behind a fulcrum of the tool. During use, the tool pivots about the bend portion applies leverage to remove a panel. The bend portion includes a cover (for example a dipped polymer) that is made of a material softer than a material of the remainder of the tool (for example, stainless steel). The tool therefore prevents scratching or other damage to panels in which the tool is used and allows greater leverage during use due to the recessed bend portion.
