Wrench Handle Display Structure for Visibility and Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wrench display structures are not distinguishable enough, especially in dim environments, and suffer from insufficient friction and durability issues with mirror surfaces and matte finishes, respectively.
Innovation Solution
A display structure for a wrench featuring a handle with recessed display areas containing embossed areas, blank areas, and colored display portions, where the embossed areas and blank areas provide tactile grip and visual differentiation, and the colored display portions are formed through painting, transfer-printing, or laser carving, offering improved visibility and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display area is made smaller to fit within the handle width, then the wrench can maintain its compact size, but the visibility and distinguishability of the display features deteriorates
Solution Approach 1:
The patent applies different colors to the display portion (first color) and the handle body (second color) to enhance visual distinguishability. The colored area is formed by painting, transfer-printing, or laser carving, making the display features more visible and distinguishable within the limited display area space.
2Shape
If a mirror surface is applied to the handle, then the aesthetic appearance is improved, but the friction and grip ability deteriorates
Solution Approach 1:
The patent applies different surface treatments to different areas: the display portion has a mirror surface for aesthetic appearance, while the handle body has a matte surface for improved friction and grip ability. This local differentiation allows each area to optimize its function.
3Loss of information
If pressed characters or patterns are formed in the display area, then the display features are created, but the molds deteriorate after period of use causing surplus material attachment
Solution Approach 1:
The patent replaces the traditional mechanical pressing method with alternative formation methods such as painting, transfer-printing, or laser carving. These methods do not require physical molds that can dull, thereby eliminating the reliability issue of mold deterioration and surplus material attachment.
4Area of stationary object
If the display area width is reduced to fit within the handle, then the wrench maintains compact dimensions, but the display distinguishability especially in dim environments deteriorates
Solution Approach 1:
The patent uses contrasting colors between the display portion and handle body to enhance visual detectability. The colored area formed by painting, transfer-printing, or laser carving stands out against the matte handle surface, making display features more detectable even in dim working environments like engine rooms.
Solution Approach 2:
The patent applies a mirror surface specifically to the display portion while keeping the handle body matte. This creates a local quality difference that enhances the visibility and detectability of the display area through light reflection, making it more distinguishable in various lighting conditions.

AI summary
A display structure for a wrench includes a handle which includes a mirror surface or a matte surface. At least one display area is formed in the handle and is a recessed area in which at least two embossed areas and at least one blank area are formed. At least one display portion is formed within the at least one display area. The at least one display portion has a colored area formed on the top thereof, so that the at least one display portion has a color that is different from that of the body of the wrench.
