Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If battery cells and electronic components are integrated in the same housing to reduce structural space, then space utilization is improved, but electromagnetic interference between components increases

Engineering Contradiction:

Improvestructural spaceVSAvoidelectromagnetic interference

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The housing is divided into a first housing region for battery cells and a second housing region for electronic components, creating spatial segmentation that reduces electromagnetic interference while maintaining compact integration. The separating element further divides the second region into multiple sub-regions for different electronic components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A separating element is introduced as an intermediary between different electronic components within the second housing region. This separator provides electromagnetic shielding and thermal management, allowing components to be closely integrated while protecting them from mutual interference.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Area of stationary object

If electronic components are arranged closer together to reduce structural space, then space utilization is improved, but thermal management difficulty increases

Engineering Contradiction:

Improvestructural spaceVSAvoidthermal management

Core Design Contradiction:

Area of stationary objectVSTemperature

Solution Approach 1:

The housing is segmented into distinct thermal zones: a first region for battery cells with dedicated coolant paths and a second region for electronic components with separate cooling arrangements. This segmentation enables independent thermal management optimized for each component type.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The separating element acts as a thermal intermediary, being thermally coupled to coolant paths to conduct heat away from electronic components. This allows efficient heat transfer from compactly arranged components without requiring large spacing for passive cooling.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If a separating element is added to provide electromagnetic shielding and thermal management, then component protection is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The separating element is designed to perform multiple functions simultaneously: electromagnetic shielding, thermal conduction, and structural support. This multi-functionality reduces the need for separate components and minimizes overall device complexity despite the added protection capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The separating element merges electromagnetic shielding and thermal management functions into a single integrated component. By combining these functions, the design avoids adding separate shielding layers and cooling structures, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #5Merging (Combining)
