Direct Cooling Handpiece Core Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handpieces with high-speed motors generate excessive heat, leading to inefficient cooling, vibrations, and noise due to indirect cooling methods such as saline solution, electric current, or air, which fail to effectively dissipate heat from the interior of the handpiece.
Innovation Solution
A direct cooling type handpiece design where the outer housing and core are spaced apart, allowing air and water to flow between them, with cooling pipes and a flowing pipe to efficiently dissipate heat, and an LED for improved visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional indirect cooling methods (saline solution, electric current, or air) are used, then the handpiece can operate, but the cooling effect is weak and heat is not efficiently dissipated
Solution Approach 1:
The patent extracts the cooling function from the traditional indirect cooling methods and implements a dedicated direct cooling system. The core is spaced apart from the outer housing to create a cooling space, and cooling pipes are specifically positioned to directly cool the core, separating the cooling function from the structural housing.
Solution Approach 2:
The patent introduces air as an intermediary cooling medium that flows through the cooling space between the core and outer housing. The flowing pipe directs air flow, and the cooling pipes facilitate heat transfer from the core to the air, creating an efficient thermal intermediary system.
2Volume of moving object
If the core is closely fitted to the outer housing, then the structure is compact, but air cannot flow to cool the core effectively
Solution Approach 1:
The patent segments the handpiece structure into distinct functional zones: the core, the cooling space between core and outer housing, and the outer housing. This segmentation creates a dedicated cooling channel while maintaining overall compactness, allowing air flow without excessive spacing.
3Productivity
If conventional cooling methods are used, then the handpiece can operate, but vibrations and noise are generated due to insufficient cooling
Solution Approach 1:
The patent implements preliminary cooling by directing air flow to the cooling space before the core overheats. The cooling pipes are positioned to pre-cool the core, preventing heat buildup that would cause vibrations and noise, thereby maintaining continuous operation without harmful effects.

AI summary
The present invention relates to a direct cooling type handpiece, and more particularly, to a direct cooling type handpiece that is configured to allow an outer housing and a core to be spaced apart from each other and thus to allow the core to be fixed to a PCB and a support cap, so that air flows to the space between the outer housing and the core, thus efficiently cooling the high heat generated from the handpiece while the handpiece is being operated.
