Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If separate cooling structures are added to cool battery packs, then heat dissipation capability is improved, but device complexity and space requirements increase

Engineering Contradiction:
Improveheat dissipation capabilityVSAvoidcooling structure complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The cooling plate integrates both the cooling function and the support function into a single component. The battery packs are directly placed on the cooling plate, which serves as both the thermal management surface and the structural support base, eliminating the need for separate support structures and reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cooling plate performs multiple functions simultaneously: it provides thermal conduction for heat dissipation, structural support for the battery packs, and serves as a mounting surface for the cooling tubes. This multi-functionality reduces the number of components needed in the system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If connection structures for cooling medium are added, then cooling system functionality is improved, but leakage risk increases

Engineering Contradiction:
Improvecooling system functionalityVSAvoidleakage prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connection structures for the cooling medium are embedded within the cooling plate itself. The cooling tubes pass through the cooling plate, and the connection points are integrated into the plate's structure, creating a nested arrangement where the connection structures are surrounded and protected by the cooling plate material.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The cooling plate, which is already present for thermal management purposes, is utilized to provide leakage protection for the cooling medium connection structures. The same component that conducts heat also serves as a barrier preventing cooling medium leakage, converting a potential harm (leakage risk at connection points) into a benefit (protected connection structures).

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A battery module includes a battery packs (M1, M2, M3). Heat may be efficiently dissipated from the battery packs (M1, M2, M3) of the battery module, and heat dissipating efficiency may not vary according to the positions of the battery packs (M1, M2, M3), that is, heat may be uniformly dissipated. In addition, leakage of a cooling medium for dissipating heat may be prevented, and permeation of the cooling medium into the battery packs (M1, M2, M3) may be prevented.
