Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grinding tools do not allow the grinder to monitor the grinding result during the process, leading to imprecise results and the need for frequent interruptions to check machining depth, especially when working with composite materials like glass fiber reinforced plastics.
Innovation Solution
A grinding tool with a rotating grinding body featuring diametrically opposite openings on its lateral surface, allowing the grinder to observe the grinding surface through the rotating tool, ensuring continuous monitoring without stopping, and optionally a hollow-cylindrical design for improved air cooling and dust extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional solid grinding wheels are used, then the grinding structure is simple and robust, but the grinder cannot observe the grinding surface during the process
Solution Approach 1:
The grinding wheel is segmented by introducing radial slots that divide the wheel structure into sections. These slots create transparent pathways allowing light to pass through the grinding wheel, enabling the grinder to observe the grinding surface during operation while maintaining the overall structural integrity of the wheel.
Solution Approach 2:
The grinding wheel incorporates a porous or translucent structure with radial slots that allow optical penetration. This design enables visibility through the grinding wheel without compromising its mechanical strength, as the slots are positioned to allow observation while the grinding peripheral surface remains intact for effective material removal.
2Measurement precision
If the grinder interrupts the grinding process to check machining depth, then they can assess the grinding result, but new grinding surfaces are created and precision is reduced
Solution Approach 1:
The radial slots in the grinding wheel enable continuous observation of the grinding surface during the entire grinding process. The grinder can monitor material removal in real-time without interrupting the grinding action, maintaining continuous useful action while achieving precise depth control through visual feedback on the bonding layer shading changes.
3Object-affected harmful factors
If conventional grinding wheels without openings are used, then the structural integrity is high, but dust extraction and cooling are insufficient
Solution Approach 1:
The radial slots segment the grinding wheel structure, creating channels that facilitate dust extraction and air flow. These segmented pathways allow efficient removal of grinding debris and improved cooling without significantly compromising the overall structural integrity, as the slots are positioned to maintain wheel strength while enabling harmful factor removal.
