Electric Vehicle Chassis Platform Module Design

Solution Overview

Problem

The existing design of electric vehicles limits the degree of freedom in design and increases manufacturing costs due to the need for separate modifications to the battery and wheel chassis modules when the vehicle body shape changes.

Innovation Solution

A chassis platform module for electric vehicles that integrates a frame with support parts for mounting the battery, front wheel chassis module, and rear wheel chassis module, allowing for common use across different vehicle designs, with features like stress distribution and separation induction parts to enhance safety and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate modifications are made to battery and wheel chassis modules when vehicle body shape changes, then vehicle design adaptability is improved, but manufacturing cost increases and design freedom decreases

Engineering Contradiction:

Improvevehicle design adaptabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The chassis system is divided into a standardized platform module (frame part with battery and wheel chassis modules) and a variable body part. This segmentation allows the platform module to remain unchanged across different vehicle models while only the body part needs modification, thereby maintaining design adaptability without increasing manufacturing complexity or cost.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The frame part and wheel chassis modules are designed as universal components that can be applied across multiple vehicle models with different body shapes. By creating a standardized interface and mounting structure, the same chassis platform module serves multiple vehicle designs, reducing per-unit manufacturing cost while preserving design freedom.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate modifications are made to battery and wheel chassis modules when vehicle body shape changes, then vehicle design adaptability is improved, but design freedom decreases

Engineering Contradiction:

Improvevehicle design adaptabilityVSAvoiddesign complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The chassis system is divided into a standardized platform module (frame part with battery and wheel chassis modules) and a variable body part. This segmentation allows the platform module to remain unchanged across different vehicle models while only the body part needs modification, thereby maintaining design adaptability without increasing manufacturing complexity or cost.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of adapting the chassis and battery modules to each new body design (traditional approach), the invention inverts the approach by adapting the body design to fit the standardized chassis platform module. This reversal simplifies the design process and maintains consistency across different vehicle models.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of manufacture

If a standardized chassis platform module is used across different vehicle designs, then manufacturing cost is reduced and design freedom is increased, but structural adaptability to different body shapes may be limited

Engineering Contradiction:

Improvemanufacturing costVSAvoidstructural adaptability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The frame part and wheel chassis modules are designed as universal components that can be applied across multiple vehicle models with different body shapes. By creating a standardized interface and mounting structure, the same chassis platform module serves multiple vehicle designs, reducing per-unit manufacturing cost while preserving design freedom.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The connection parts are designed with flexible connection methods that allow adjustment and adaptation to different body mounting positions and orientations. This dynamic adaptability enables the standardized chassis module to accommodate various body shapes without requiring structural modifications to the platform itself.

Inventive Principle:

Principle #15Dynamics
