Solution Overview
Problem
Conventional surface preparation methods using grinding tools or rotary tools result in lower paint adhesiveness due to scratch patterns, while blast methods require large-scale preparation and generate significant waste, making them inefficient and difficult to perform.
Innovation Solution
A surface treatment system with a surface treatment member featuring a base mountable on a rotary member and a striking member that impinges on the surface treatment object, imparting an impact, with a stopper regulating the rotational angle of the striking member to prevent scratch patterns and enhance paint adhesiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a grinding tool or rotary tool is used for surface preparation, then the surface can be treated easily, but scratch patterns are formed which reduce paint adhesiveness
Solution Approach 1:
Instead of using abrasive materials to remove surface layers (conventional grinding), the invention inverts the approach by using impact forces to create compressive stress and dot-shaped凹凸 structures. This inversion transforms the surface treatment mechanism from material removal to structural modification, achieving both ease of operation and improved surface pattern quality for paint adhesiveness
Solution Approach 2:
The invention replaces the conventional mechanical abrasion system (grinding discs, belts) with an impact-based mechanical system. The striking member delivers controlled impacts to create the desired surface pattern, substituting the continuous rubbing action of grinding tools with discrete impact events, thereby eliminating scratch patterns while maintaining operational simplicity
2Manufacturing precision
If a blast method is used for surface preparation, then paint adhesiveness is improved, but large-scale preparation is required and significant waste is generated
Solution Approach 1:
The invention extracts the essential beneficial effect of blast cleaning (dot-shaped surface pattern for paint adhesion) while removing the harmful aspects (large-scale preparation requirements and waste generation). By using a localized striking member that creates compressive stress and dot patterns through controlled impacts, the system achieves blast-like surface preparation in a compact, waste-free manner
Solution Approach 2:
The invention changes the fundamental parameters of surface preparation by transitioning from a high-energy, material-removal blast process to a low-energy, structure-modification impact process. The striking member parameters (mass, velocity, impact frequency) are optimized to create the desired dot-shaped凹凸 structures without generating significant waste, thereby improving surface pattern quality while minimizing substance loss
3Manufacturing precision
If a striking member is rotatably mounted on the base, then dot-shaped凹凸 are formed improving paint adhesiveness, but the rotational angle control is required
Solution Approach 1:
The striking member is designed to automatically regulate its own rotational angle through the interaction between the stopper and its protrusion. As the striking member rotates, the stopper protrusion engages with the stopper groove, automatically limiting the rotation to the optimal angle range for creating dot-shaped patterns. This self-regulating mechanism achieves precise surface pattern control without requiring complex external angle control systems
Solution Approach 2:
The stopper acts as an intermediary element between the striking member and the base, mediating the rotational motion. The stopper protrusion and groove create a mechanical interface that automatically controls the striking member's rotation angle, translating the rotational movement into the desired impact pattern on the workpiece surface while simplifying the overall control mechanism

AI summary
Provided with a surface treatment member 1 used by being mounted on a rotary member in a surface treatment system including the rotary member. The surface treatment member 1 includes: a base 10; and a striking member 40 being rotatably mounted on the base 10 and being configured to impinge on a surface treatment object and to impart an impact to the surface treatment object when using, wherein the base 10 has a stopper 20 that regulates a rotational angle of the striking member 40. By using the surface treatment member 1 of the present invention to the surface treatment system that includes the rotary member, when the surface preparation is performed, the adhesiveness of a paint can be enhanced and, at the same time, the surface preparation can be performed easily. Further, in the surface treatment member 1, the base 10 has the stopper 20 and hence, it is possible to make the striking member 40 properly impinge on the surface treatment object by controlling the rotation of the striking member 40.
