1Loss of energy

If conventional heat dissipation methods (fan or fins) are used, then the storage device can operate, but the heat dissipation efficiency is low

Engineering Contradiction:

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The patent introduces a working fluid as an intermediary substance between the storage module and the external environment. The storage module is immersed in the working fluid, which acts as a heat transfer medium to conduct heat from the storage module to the case, significantly improving heat dissipation efficiency compared to conventional fan or fin methods.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent utilizes hydraulic principles by employing a liquid working fluid for heat dissipation. The working fluid circulates within the sealed case, absorbing heat from the storage module through immersion and conducting it to the case walls, leveraging the high heat capacity and thermal conductivity of liquids to achieve efficient heat removal.

Inventive Principle:

Solution Approach 1:

The patent ensures continuous heat dissipation by immersing the storage module in the working fluid, which continuously absorbs heat as it conducts from the storage module to the case. This continuous heat removal process allows the storage device to maintain high-performance operation without temperature-induced performance degradation.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent changes the thermal parameters of the operating environment by introducing the working fluid, which has favorable thermal properties (high heat capacity and thermal conductivity). This parameter change in the heat dissipation medium enables the storage module to operate at higher temperatures without reaching critical thermal thresholds that would reduce transmission speed.

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The patent merges the heat dissipation function with the existing case structure. The case is designed to contain the working fluid and serve as both the structural enclosure and the heat dissipation chamber. The storage module is immersed directly in the fluid within the case, eliminating the need for separate heat dissipation components and reducing overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The working fluid serves multiple functions: it acts as a heat transfer medium, a cooling agent, and a thermal buffer. The case simultaneously serves as the structural housing and the heat dissipation chamber. This multi-functionality approach improves heat dissipation efficiency without proportionally increasing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
