Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If electronic components are arranged separately in the battery package, then each component can be manufactured and installed independently, but the overall volume of the battery package increases

Engineering Contradiction:

ImproveIndependent component manufacturing and installationVSAvoidBattery package volume

Core Design Contradiction:

Ease of manufactureVSVolume of stationary object

Solution Approach 1:

The patent integrates the electronic equipment chamber directly into the battery package structure, merging previously separate components (battery package and electronic components) into a single integrated unit. This reduces the overall volume while maintaining independent manufacturability through modular design of the electronic equipment chamber board.

Inventive Principle:

Principle #5Merging (Combining)

2Use of energy by moving object

If busbars are positioned close to electronic components for efficient electrical connection, then electrical connection efficiency improves, but electromagnetic field errors increase affecting other electronic components

Engineering Contradiction:

ImproveElectrical connection efficiencyVSAvoidElectromagnetic field errors

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the busbars from the immediate vicinity of sensitive electronic components by positioning them along the outer edge of the electronic equipment chamber board, while still maintaining efficient electrical connections through optimized routing. This separation reduces electromagnetic interference while preserving electrical connection efficiency.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different spatial arrangements to different components based on their sensitivity to electromagnetic fields. Sensitive electronic components are positioned in the center away from high-current busbars, while less sensitive components can be positioned closer to busbars, creating local quality variations in component placement.

Inventive Principle:

Principle #3Local quality

3Volume of stationary object

If the electronic equipment chamber is designed with compact component arrangement, then product volume is reduced, but component operation stability may be compromised

Engineering Contradiction:

ImproveElectronic equipment chamber volumeVSAvoidElectronic component operation stability

Core Design Contradiction:

Volume of stationary objectVSReliability

Solution Approach 1:

The patent utilizes the outer edge dimension of the electronic equipment chamber board for busbar placement, effectively using the perimeter space rather than consuming central area. This dimensional optimization allows compact overall volume while maintaining stable component operation through appropriate spacing.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
