Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface preparation methods using grinding tools or rotary tools result in scratch patterns, reducing paint adhesiveness, while blasting methods generate excessive waste and are inefficient.
Innovation Solution
A surface treatment system with a rotary member and a striking member having an annular body and protruding portions that impart impact to the surface, retracting after contact to form dot-shaped concaves and convexes without scratch patterns, enhancing paint adhesiveness and simplifying the preparation process.
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 that reduce paint adhesiveness
Solution Approach 1:
The striking member is divided into multiple protruding portions (e.g., 3-10 protrusions) distributed around the annular body. Each protrusion independently impacts the surface to create dot-shaped凹部, avoiding continuous scratch patterns while maintaining ease of operation through rotational motion.
Solution Approach 2:
The striking member rotates periodically to create intermittent impact points on the surface. As the annular body with discrete protrusions rotates, each protrusion sequentially impacts the surface at different locations, forming a pattern of isolated凹部 rather than continuous scratches, thereby improving paint adhesiveness while maintaining operational simplicity.
2Reliability
If a blasting method is used for surface preparation, then paint adhesiveness is improved, but a large amount of waste is generated and the process becomes complex
Solution Approach 1:
The invention replaces the blasting method's pneumatic/mechanical particle projection system with a controlled rotational impact system. Instead of using compressed air to propel abrasive particles that generate dust waste, the striking member uses its own weight and rotational kinetic energy to create localized impacts, significantly reducing substance loss while achieving similar surface preparation效果.
Solution Approach 2:
The invention changes the impact parameters from continuous particle bombardment (blasting) to discrete localized impacts from protruding portions. By controlling the number, shape, and distribution of protrusions on the annular striking member, the surface凹部 pattern is optimized for paint adhesiveness without generating excessive waste material.
3Reliability
If a blasting method is used for surface preparation, then paint adhesiveness is improved, but the preparation process becomes difficult and time-consuming
Solution Approach 1:
The striking member maintains continuous rotational contact with the surface, ensuring that the entire treatment area receives consistent impact treatment. The rotation continues smoothly without interruption, creating uniform dot-shaped凹部 across the surface, which improves both paint adhesiveness and processing efficiency compared to the intermittent and complex blasting process.
Solution Approach 2:
The striking member utilizes rotational dynamics to maintain consistent impact force across the surface. The centrifugal force and rotational velocity ensure that each protruding portion delivers controlled impacts as it passes over the surface, creating uniform preparation quality throughout the treatment area while maintaining high productivity through continuous motion.

AI summary
Provided is a surface treatment member used by being mounted on a rotary member in a surface treatment system including the rotary member. The surface treatment member includes: a base; a striking member having an annular body portion and a protruding portion that protrudes from the body portion; and a shaft member disposed in a region on an inner side of the body portion. When the surface treatment member is viewed along an imaginary axis about which the base is to be rotated, a portion of the striking member is exposed outside an outer periphery of the base by a centrifugal force when the surface treatment member is rotated, and an entirety of the striking member is retractable toward inside an imaginary circle that passes over an outermost periphery of the base about the imaginary axis after the striking member impinges on a surface treatment object.
