Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the battery pack is integrated directly in the frame with custom positioning for each model, then the energy storage system can be optimally positioned for each specific carriage model, but the number of variant embodiments increases and design complexity increases

Engineering Contradiction:
Improvebattery positioning optimizationVSAvoidnumber of variant embodiments
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The energy storage system is divided into modular battery packs that can be independently positioned in standardized zones within the frame. Each battery pack is a self-contained module with standardized dimensions and mounting interfaces, allowing them to be segmented and reconfigured across different carriage models without requiring custom integration designs for each variant.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame structure incorporates universal standardized zones that can accommodate different battery pack configurations across multiple carriage models. These zones are designed with standardized dimensions and mounting points that work across various carriage types, allowing the same frame design to serve multiple functions and models while reducing the number of variant embodiments needed.

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

2Manufacturing precision

If custom battery pack integration is designed for each carriage model, then optimal energy storage positioning is achieved for each model, but design and production simplification is hindered

Engineering Contradiction:

Solution Approach 1:

The energy storage system is divided into modular battery packs that can be independently positioned in standardized zones within the frame. Each battery pack is a self-contained module with standardized dimensions and mounting interfaces, allowing them to be segmented and reconfigured across different carriage models without requiring custom integration designs for each variant.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the design parameter from custom-fit battery integration to standardized modular battery packs with fixed dimensions. This parameter change allows the same standardized battery packs to be used across different carriage models by simply changing their positioning within standardized zones, thereby simplifying design and production while maintaining optimal energy storage positioning.

Inventive Principle:
