Modular Grinder Cover System for Dust Control and Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grinders require frequent changes of protective covers for different tool accessories, which is labor-intensive and reduces work efficiency due to interference between the cover and workpiece, especially when performing multiple processing tasks in a short period.
Innovation Solution
A modular cover system comprising a first cover fixed to the housing and a detachable second cover that can be mounted or dismounted based on the tool accessory and processing method, allowing adjustment of coverage area to prevent interference and improve dust reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the surface area of the protective cover is increased to reduce dust dispersion, then dust reduction is improved, but the cover interferes with the workpiece, reducing work efficiency and processing performance
Solution Approach 1:
The protective cover is divided into a first cover that is fixed to the housing and a second cover that is detachably mounted on the first cover. This segmentation allows the second cover to be removed when not needed, preventing interference with the workpiece while maintaining dust reduction capability when the second cover is attached.
Solution Approach 2:
The second cover is designed to be detachably mounted on the first cover, allowing dynamic adjustment of the cover configuration. The second cover can be attached when dust reduction is prioritized and detached when work efficiency is prioritized, making the system adaptable to different operational requirements.
2Manufacturing precision
If a specialized protective cover is prepared for each type of tool accessory to achieve high work efficiency and processing performance, then processing performance is improved, but exchanging the protective cover becomes labor intensive
Solution Approach 1:
The first cover is designed as a universal base that can accommodate different tool accessories. The second cover, which provides additional coverage, is detachably mounted on the first cover and can be configured in different orientations. This universal design allows a single cover set to serve multiple processing functions (grinding, cutting, polishing) without requiring multiple specialized covers, significantly reducing exchange time and labor.
3Area of stationary object
If the second cover is mounted in a first orientation with inner surfaces opposing each other to cover areas below the tool accessory, then coverage area is improved, but the configuration must be changed for different processing methods
Solution Approach 1:
The second cover is designed to be detachably mounted on the first cover in different orientations. When mounted in the first orientation, the inner surfaces oppose each other to cover areas below the tool accessory. When mounted in a second orientation, the outer surface of the first cover and the inner surface of the second cover approach each other. This dynamic reconfigurability allows a single second cover to adapt to different processing methods without requiring multiple specialized covers.

AI summary
A cover set (110; 210; 310; 410; 510; 610; 710; 810) at least partially covers a tool accessory (40), which is mounted on a spindle (24) that protrudes downward from a housing (4, 6, 30) of a grinder (100; 200; 300; 400; 500; 600; 700; 800). The cover set (110; 210; 310; 410; 510; 610; 710; 810) includes a first cover (120; 420; 520; 620; 720; 820) and a second cover (170; 270; 370; 470; 570; 670; 770; 870). The first cover (120; 420; 520; 620; 720; 820) is fixed to the housing (4, 6, 30), and at least partially covers the tool accessory (40), which is mounted on the spindle (24), from above. The second cover (170; 270; 370; 470; 570; 670; 770; 870) at least partially covers the tool accessory (40) in association with the first cover (120; 420; 520; 620; 720; 820). The second cover (170; 270; 370; 470; 570; 670; 770; 870) is for optional use.
