Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If vehicle equipment is optimized according to user's driving characteristics, then driving comfort and performance are improved, but battery degradation is not prevented or reduced

Engineering Contradiction:
Improvedriving comfortVSAvoidbattery lifespan
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cooling control unit dynamically adjusts the cooling intensity based on real-time driving characteristics and battery status. The system transitions from static cooling control to dynamic adjustment, matching cooling intensity to actual battery burden and driving conditions, thereby preventing battery degradation while maintaining driving comfort.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements a feedback mechanism where the cooling control unit continuously monitors driving characteristics through the data collection unit and adjusts cooling intensity based on analysis results. This closed-loop control ensures that cooling measures are appropriately adapted to actual battery conditions and driving patterns.

Inventive Principle:
Principle #23Feedback

2Reliability

If cooling intensity is increased to prevent battery degradation, then battery lifespan is extended, but energy consumption increases

Engineering Contradiction:
Improvebattery lifespanVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system applies partial cooling action by adjusting cooling intensity to match actual battery burden. Instead of applying maximum cooling continuously, the system provides just enough cooling to prevent degradation based on analyzed driving characteristics, avoiding excessive energy consumption while still protecting the battery.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The cooling control unit changes the parameter of cooling intensity dynamically based on driving characteristics and battery status. By adjusting this parameter according to actual needs rather than maintaining constant high intensity, the system extends battery lifespan while minimizing energy consumption.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If cooling intensity is adjusted according to driving characteristics, then battery degradation is reduced, but system complexity increases

Engineering Contradiction:
Improvebattery lifespanVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cooling control unit serves multiple functions: it controls cooling intensity, analyzes driving characteristics, and prevents battery degradation. By making the cooling system multi-functional and integrating it with the existing vehicle control architecture, the system reduces overall complexity while achieving battery protection.

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

Solution Approach 2:

The system enables the cooling unit to automatically adjust its operation based on analyzed driving characteristics without requiring complex external intervention. The cooling control unit serves itself by integrating the analysis and control functions, simplifying the overall system architecture while maintaining effective battery protection.

Inventive Principle:
Principle #25Self-service
