Solution Overview

Problem

Vehicle manufacturers face challenges in developing versatile vehicle parts that can be applied to different models and connected to components with varying structures, necessitating a solution that enhances adaptability and reduces design and production costs.

Innovation Solution

A front floor design with a recessed or protruding interface structure that allows for adjustable connection with a rear floor, enabling flexibility in size and shape matching, and includes features like clearance structures to accommodate additional components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a front floor is designed with a fixed interface structure, then the manufacturing precision and structural stability are improved, but the adaptability to different rear floor sizes and shapes deteriorates

Engineering Contradiction:
Improveinterface structure precisionVSAvoidadaptability to different rear floors
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The interface structure incorporates an adjustable mechanism that allows the connection position and orientation to be modified after manufacturing. This dynamic adjustment capability enables the same front floor to adapt to different rear floor configurations while maintaining precise connection, thus resolving the contradiction between manufacturing precision and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The interface structure is divided into multiple adjustable segments or modules that can be independently positioned and configured. This segmentation allows flexible adaptation to different rear floor shapes and sizes while each segment maintains its own manufacturing precision standards.

Inventive Principle:
Principle #1Segmentation

2Productivity

If vehicle parts are designed for multiple models, then the productivity and cost efficiency are improved, but the device complexity increases

Engineering Contradiction:
Improveproduction efficiencyVSAvoiddesign complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The front floor interface structure is designed with universal adjustment capabilities that allow it to function with multiple different rear floor configurations. This multi-functionality enables a single design to serve multiple vehicle models, improving productivity while the modular adjustment mechanisms actually reduce overall design complexity compared to creating separate designs for each model.

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

Solution Approach 2:

The interface structure allows for parameter adjustments (position, orientation, connection depth) after manufacturing, enabling the same physical component to adapt to different requirements. This parameter flexibility achieves universality across models without requiring complex multi-version designs.

Inventive Principle:
Principle #35Parameter changes
