Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional cooling concepts are used, then the structure is simple, but rapid and uniform heat dissipation cannot be achieved

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoidcooling system structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cooling system is segmented into multiple independently controllable cooling zones, each corresponding to a specific battery cell or group of cells. This allows targeted cooling of individual cells or regions with different thermal requirements, enabling rapid and uniform heat dissipation across the entire battery system while maintaining manageable structural complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the battery system are provided with locally optimized cooling solutions based on their specific thermal characteristics and power density. The cooling system adapts its parameters (flow rate, temperature) to local requirements, achieving superior heat dissipation efficiency without requiring a completely complex centralized system

Inventive Principle:
Principle #3Local quality

2Use of energy by moving object

If high power output is achieved, then energy density increases, but thermal imbalance and overheating occur

Engineering Contradiction:
Improveenergy densityVSAvoidthermal balance
Core Design Contradiction:
Use of energy by moving objectVSTemperature

Solution Approach 1:

The cooling system incorporates temperature sensors and control mechanisms that continuously monitor the thermal state of battery cells and adjust cooling parameters in real-time. This feedback control prevents thermal imbalance by detecting temperature deviations early and applying corrective cooling to specific cells, allowing the system to operate at high power densities while maintaining thermal balance

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The cooling system dynamically adjusts its operation based on real-time battery conditions, varying flow rates, temperatures, and active cooling zones according to the battery's instantaneous power demands and thermal state. This dynamic adaptation enables the system to handle high power output scenarios while preventing overheating and thermal imbalance

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If uniform cooling is applied to all cells, then thermal balance is maintained, but cells with different power densities cannot be optimized individually

Engineering Contradiction:
Improvethermal equilibriumVSAvoidpower density optimization
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The cooling system implements locally differentiated cooling strategies where each cooling zone can be independently controlled according to the specific power density and thermal characteristics of the corresponding battery cells. This allows cells with higher power densities to receive more aggressive cooling while maintaining thermal equilibrium across the entire system, optimizing overall productivity without sacrificing thermal balance

Inventive Principle:
Principle #3Local quality
