Grinding Machine Tool Circuit Board Layout for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric grinding machine tools have a high gravity center due to the placement of the circuit board at the top, leading to instability and heat-related discomfort during use, making it difficult for users to operate them effectively, especially when grinding upright surfaces.
Innovation Solution
The circuit board is repositioned to be on the side of the tool shaft, opposite the battery mount, and ventilation holes are incorporated to enhance heat dissipation, reducing the grip body's height and lowering its gravity center, while maintaining efficient operation and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the circuit board is arranged at the top end of the tool shaft, then the internal components can be linearly configured, but the gravity center of the grip body cannot be lowered, causing instability
Solution Approach 1:
The circuit board is repositioned from a vertical arrangement at the top end of the tool shaft to a lateral arrangement on the side surface of the grip body. This dimensional change in component layout allows the circuit board to be positioned in a different spatial plane, reducing the overall height of the grip body and lowering the gravity center to improve stability during operation
2Device complexity
If the circuit board is arranged at the top end of the tool shaft, then the component layout is simplified, but the temperature of the grip body increases, affecting user comfort
Solution Approach 1:
The circuit board is extracted from its conventional position at the top end of the tool shaft and relocated to the side surface of the grip body. This extraction and relocation separates the heat-generating component from the user's hand contact area, effectively reducing the temperature experienced by the user during operation while maintaining the functional integration of the device
