Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If battery and ESC are integrated into vehicle design in a fixed manner, then structural stability is improved, but adaptability and ease of operation deteriorate

Engineering Contradiction:

Improvestructural stabilityVSAvoidadaptability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The battery system is divided into multiple modular battery units that can be independently attached or detached from the vehicle. Each battery unit connects to the vehicle frame through standardized mounting interfaces, allowing the battery capacity to be adjusted by adding or removing units without affecting the overall vehicle structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The battery and ESC components are designed with dynamic attachment and detachment capabilities. The mounting system allows for quick connection and disconnection of battery units and ESC modules, enabling users to reconfigure the powertrain setup based on different operational requirements or vehicle types.

Inventive Principle:

Principle #15Dynamics
