Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The gap around pluggable electronic elements in electronic devices creates an air layer with high thermal resistance, leading to poor heat dissipation when the elements are plugged in.
Innovation Solution
A housing with an accommodating groove and inclined surface, combined with a heat conduction sheet and thin film, guides the pluggable heat source for direct heat dissipation and stabilizes the insertion process, minimizing contact with the thin film during plugging/unplugging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gap is reserved around the pluggable electronic element to ensure smooth insertion, then the ease of operation is improved, but the heat dissipation performance deteriorates due to the formation of an air layer with high thermal resistance
Solution Approach 1:
A heat conduction sheet is introduced as an intermediary substance between the pluggable electronic element and the housing. This sheet fills the gap that was previously filled with air, providing both thermal conduction pathways and maintaining the necessary clearance for smooth insertion. The heat conduction sheet has thermal conductivity significantly higher than air, thus resolving the thermal resistance issue while preserving the operational ease benefit of having a gap.
Solution Approach 2:
The thermal conductivity parameter of the medium in the gap is changed from air (low thermal conductivity) to heat conduction sheet material (high thermal conductivity). This parameter change transforms the thermal properties of the gap-filling material while maintaining the geometric gap structure, thereby improving heat dissipation without affecting the mechanical clearance needed for smooth insertion.
2Temperature
If the heat conduction sheet is placed in direct contact with the pluggable heat source, then the heat dissipation efficiency is improved, but the risk of damage to the thin film during insertion increases
Solution Approach 1:
The heat conduction sheet is pre-positioned in the housing before the pluggable heat source is inserted. The sheet is arranged to extend across the insertion path, creating a protective barrier that guides the heat source into its final position. This preliminary arrangement ensures that the heat source makes controlled contact with the heat conduction sheet rather than directly with the thin film, preventing damage while establishing thermal contact.
Solution Approach 2:
The heat conduction sheet serves as a mediator between the pluggable heat source and the thin film structure. During insertion, the heat source contacts the heat conduction sheet first, which then transfers the thermal contact force in a controlled manner, preventing direct impact on the thin film. This intermediary role allows efficient thermal coupling while protecting the fragile thin film from mechanical damage.
