Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple mounting bracket is used to attach the battery to the vehicle frame, then the device complexity is reduced, but the stability and security of the battery attachment deteriorates

Engineering Contradiction:

Improvemounting bracket structureVSAvoidbattery attachment security

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The mounting bracket is segmented into multiple functional components: a base for frame attachment, vertical walls for battery containment, horizontal tabs for lateral securing, and drainage features. This segmentation allows each component to perform its specific function optimally while maintaining overall structural integrity and battery security.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting bracket extends in multiple dimensions with vertical walls rising from the base and horizontal tabs extending outward, creating a three-dimensional structure that secures the battery from multiple directions (laterally, vertically, and longitudinally) rather than relying on a single-plane attachment.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If the mounting bracket is made from high-strength steel with phosphate coating to prevent corrosion, then the corrosion resistance improves, but the weight of the mounting bracket increases

Engineering Contradiction:

Improvecorrosion resistanceVSAvoidmounting bracket weight

Core Design Contradiction:

Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The mounting bracket utilizes a composite approach by combining high-strength steel base material with a phosphate coating layer. This composite structure provides superior corrosion resistance through the phosphate coating while the high-strength steel provides the necessary mechanical properties, optimizing the balance between protection and weight.

Inventive Principle:

Principle #40Composite materials

3Stability of the object's composition

If multiple tabs and walls are added to the mounting bracket to secure the battery firmly, then the battery stability improves, but the manufacturing complexity increases

Engineering Contradiction:

Improvebattery positioning stabilityVSAvoidmounting bracket fabrication

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple securing functions are merged into a single integrated mounting bracket structure. The base, walls, and tabs are combined into one piece that simultaneously provides frame attachment, lateral battery securing, and structural support, reducing the number of separate components needed.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If fastener holes are provided in the base and walls for secure attachment, then the reliability of mounting improves, but the device complexity increases

Engineering Contradiction:

Improvemounting securityVSAvoidfastener hole configuration

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The mounting bracket is designed as a multi-functional component that simultaneously serves as the mounting structure itself, provides attachment points via integrated fastener holes in the base and walls, and offers battery containment. This universality eliminates the need for separate mounting brackets and attachment hardware.

Inventive Principle:

Principle #6Universality (Multi-functionality)
