Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional cooling systems are used to cool individual battery cells or modules, then cooling function is provided, but uniform temperature control across the entire power storage system cannot be achieved and system complexity increases

Engineering Contradiction:
Improvetemperature uniformityVSAvoidcooling system complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The power storage system is divided into modular battery packs, each containing multiple battery modules with integrated cooling channels. This segmentation allows the cooling system to be scaled and configured according to specific needs, reducing overall system complexity while maintaining uniform temperature control across the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cooling system is designed with a unified thermal management architecture that can simultaneously cool multiple battery modules through integrated cooling channels and heat transfer plates. This multi-functional design eliminates the need for separate cooling systems for each module, reducing system complexity while achieving uniform temperature control.

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

2Quantity of substance

If high-capacity battery modules are used to increase power storage capacity, then energy density is improved, but heat generation during charging and discharging increases dramatically

Engineering Contradiction:
Improvebattery capacityVSAvoidheat generation
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

Heat transfer plates are introduced as intermediary components between battery modules and cooling channels. These plates efficiently conduct heat away from high-capacity battery modules during charging and discharging, managing the increased heat generation without compromising the energy density benefits of large-capacity batteries.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

A liquid cooling system with circulating coolant is implemented to manage heat generation from high-capacity battery modules. The hydraulic cooling system efficiently removes heat during high-rate charging and discharging, enabling the use of large-capacity batteries while controlling thermal effects.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Measurement precision

If independent cooling operations are employed for each battery cell or module, then individual temperature control is achieved, but excessive cooling occurs due to overlapping cooling zones

Engineering Contradiction:
Improvetemperature control precisionVSAvoidenergy efficiency
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

Multiple cooling channels are merged into a unified cooling system with integrated flow paths and centralized control. This merging eliminates overlapping cooling zones and redundant cooling operations, preventing excessive cooling while maintaining precise temperature control through coordinated operation of the integrated system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Temperature sensors and control systems are implemented to monitor and adjust cooling operations in real-time. This feedback mechanism prevents excessive cooling by dynamically adjusting coolant flow and cooling intensity based on actual thermal conditions, improving energy efficiency while maintaining precise temperature control.

Inventive Principle:
Principle #23Feedback
