Solution Overview
Problem
Conventional machine tools face challenges in effectively dissipating heat generated by motors and circuit boards, leading to overheating, and existing heat dissipation structures allow dust to enter and damage electronic components.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation holes are formed in the handle to dissipate heat from the circuit board, then heat dissipation is improved, but dust can enter and damage electronic components
Solution Approach 1:
The heat dissipation function is segmented from the handle structure by introducing a separate heat dissipation seat with heat dissipation members, while the handle maintains its sealed accommodation space for the circuit board. This allows heat dissipation without compromising dust protection.
Solution Approach 2:
The heat dissipation seat acts as an intermediary structure that receives heat from the circuit board through the carrying member and dissipates it externally through heat dissipation members, without requiring direct openings in the handle. This mediates between heat dissipation needs and dust protection requirements.
2Temperature
If conventional heat dissipation structures with openings are used, then heat dissipation is achieved, but the structure complexity increases and manufacturing time is consumed
Solution Approach 1:
The heat dissipation seat integrates multiple functions: it carries the circuit board, conducts heat from the circuit board, and dissipates heat through its own heat dissipation members. This merging of functions reduces the need for separate heat dissipation openings in the handle, simplifying the overall structure.
Solution Approach 2:
The heat dissipation seat serves multiple purposes: supporting the circuit board, providing a thermal conduction path, and acting as a heat dissipation radiator. This multi-functionality eliminates the need for additional dedicated heat dissipation structures in the handle.
