Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand tools slip easily on oily surfaces, limiting their versatility and requiring additional tools for burr removal, which increases operational inconvenience and time.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional smooth surface is used on the main body, then the tool is easy to manufacture, but the friction force is insufficient and the main body slips on oily surfaces
Solution Approach 1:
The patent applies laser processing to fundamentally change the surface parameters of the main body, transforming it from a smooth finish to a roughened surface with controlled particle structures. This parameter change increases the coefficient of friction without requiring mechanical attachment of separate friction elements, resolving the contradiction between ease of operation and ease of manufacture.
Solution Approach 2:
The patent replaces traditional mechanical surface modification methods (such as knurling, embossing, or attaching separate friction surfaces) with laser-based thermal processing. This substitution eliminates the need for additional mechanical components while achieving the desired friction enhancement, thereby maintaining ease of manufacture.
2Ease of operation
If only a grinding face is added to provide anti-slip function, then the friction performance is improved, but the versatility of the hand tool is limited
Solution Approach 1:
The patent makes the main body itself multi-functional by integrating both gripping and grinding capabilities into a single component. The laser-processed surface provides friction for gripping, while the same surface can remove burrs from workpieces, eliminating the need for separate specialized tools and thereby enhancing versatility.
Solution Approach 2:
The patent merges the functions of a gripping surface and a grinding surface into the main body structure. Instead of having separate components for anti-slip and burr removal, the laser-processed main body simultaneously provides both functions, combining multiple tool capabilities into one unified component.
3Productivity
If additional tools are used for burr removal, then the burr removal function is achieved, but the operational time and complexity increase
Solution Approach 1:
The patent enables the main body to serve itself by incorporating burr removal capability directly into the gripping surface. The laser-processed roughened surface that provides friction for gripping also acts as an effective burr removal tool, allowing the same component to perform multiple functions without requiring separate specialized tools.
Solution Approach 2:
The patent creates a universal tool where the main body can both grip workpieces and remove burrs. This multi-functionality eliminates the need for additional specialized burr removal tools, thereby reducing the total number of tools required and decreasing operational complexity and time.
