Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photographing apparatuses face challenges in miniaturizing the driving motor and moving the pickup device in the optical axial direction due to frictional forces generated by heat transfer plates during heat radiation, which complicates precise and efficient heat dissipation.
Innovation Solution
A pickup device driving apparatus with a heat radiation part that allows heat to escape through radiation without generating frictional forces, featuring convex parts on the heat radiation part to increase radiation efficiency and a heat sink part for effective cooling, ensuring the heat radiation part does not come into contact with the heat sink part within the movement range of the pickup device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat transfer plate is provided in contact with the case to transfer heat, then heat dissipation is improved, but frictional force is generated between the heat transfer plate and the case when the pickup device moves
Solution Approach 1:
The patent extracts the heat dissipation function from the mechanical contact structure. Instead of using a heat transfer plate that physically contacts the case (which generates friction), the invention uses a heat radiation part that radiates heat through electromagnetic waves. This separates the heat transfer mechanism from mechanical contact, eliminating friction while maintaining effective heat dissipation.
Solution Approach 2:
The patent replaces the mechanical heat transfer system (heat transfer plate in contact with case) with a thermal radiation system. The heat radiation part emits thermal energy through radiation rather than requiring physical contact for heat transfer. This substitution eliminates the frictional force that would otherwise be generated during pickup device movement while maintaining heat dissipation effectiveness.
2Temperature
If a heat transfer plate is used for heat dissipation, then heat management is improved, but the driving motor size increases due to the need for larger force to overcome friction
Solution Approach 1:
The invention extracts the heat dissipation function from the mechanical drive system. By using thermal radiation instead of contact-based heat transfer, the patent eliminates the friction that would require additional motor force, thereby enabling motor miniaturization while maintaining effective heat management.
Solution Approach 2:
The patent replaces the mechanical contact-based heat transfer system with a thermal radiation system. This substitution eliminates frictional forces during pickup device movement, reducing the force requirements for the driving motor and enabling motor size reduction while maintaining heat dissipation performance.
3Temperature
If the heat radiation part is positioned close to the heat sink part for effective heat transfer, then heat dissipation efficiency is improved, but contact may occur during pickup device movement generating friction
Solution Approach 1:
The patent replaces mechanical contact-based heat transfer with thermal radiation. The heat radiation part can be positioned near the heat sink part for efficient heat transfer through radiation, without requiring physical contact. This eliminates friction during pickup device movement while maintaining heat dissipation efficiency.
Solution Approach 2:
The patent uses thermal radiation as an intermediary mechanism for heat transfer between the heat radiation part and heat sink part. This radiation-based intermediary allows heat transfer without direct mechanical contact, eliminating friction while maintaining efficient heat dissipation even when components are positioned close together.
