Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling heat dissipation modules in electronic devices are prone to leakage during transportation due to pipe disconnection or breakage, which can lead to short circuits when leaking liquids come into contact with internal components.
Innovation Solution
A leakage detection system comprising a substrate with sensing units and an absorbent layer that detects and absorbs leaks, guiding them to the sensing units, while an isolation layer prevents external liquids from interfering, and a processing module generates a warning signal upon detection, transmitted to a buzzer or software interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid cooling modules are used for heat dissipation, then heat dissipation effectiveness is improved, but the risk of leakage and short circuit increases
Solution Approach 1:
The sensing unit is pre-installed on the substrate to detect leakage before it causes damage. The absorbent layer is pre-positioned to immediately absorb any leaking liquid, guiding it away from electronic components. This preliminary arrangement of detection and absorption mechanisms prevents the worsening effect before it occurs.
Solution Approach 2:
The absorbent layer acts as an intermediary between the leakage source and electronic components. It absorbs the cooling liquid and guides it to the sensing unit, preventing direct contact between the liquid and electronic components. This intermediary mechanism resolves the contradiction by allowing liquid cooling to function while blocking the harmful pathway.
2Reliability
If sensing units are added to detect leakage, then reliability is improved, but device complexity increases
Solution Approach 1:
The sensing unit is integrated directly onto the substrate, merging the detection function with the existing structural platform. The absorbent layer is combined with the substrate to form an integrated assembly. This merging approach improves reliability by adding detection capability while minimizing the increase in device complexity through unified design.
Solution Approach 2:
The substrate serves multiple functions: it provides structural support, hosts the sensing unit for leakage detection, and works with the absorbent layer to manage liquid flow. This multi-functionality approach allows the system to gain detection capability without proportionally increasing complexity, as existing components are made to serve additional purposes.
3Object-affected harmful factors
If absorbent layer is added to guide leakage liquid, then harmful effects are reduced, but device complexity increases
Solution Approach 1:
The absorbent layer converts the harmful effect of leakage liquid into a beneficial controlled flow. Instead of allowing liquid to randomly spread and cause damage, the absorbent layer guides the liquid to a specific location (the sensing unit). This transforms the harmful uncontrolled leakage into a beneficial controlled detection process, reducing damage while adding only minimal structural complexity.
