Solution Overview

Problem

The vehicle industry faces increased production costs due to the development of vehicle bodies tailored for specific customized services, necessitating a solution for easily interchangeable replaceable parts that can adapt to different uses without altering the fixed components.

Innovation Solution

A replaceable part replacement system featuring a station frame, support frame, and gripper unit that allows for the easy exchange of replaceable parts by positioning the vehicle on a station frame, moving the support frame, and using gripper units to grip and release parts via electromagnetic forces and vertical movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the upper body structure is developed separately for each customized service type, then the vehicle can provide various customized services, but the production cost increases

Engineering Contradiction:

Improvecustomized service capabilityVSAvoidproduction cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The vehicle body is divided into a fixed part (front cabin and underbody) and a replaceable part (rear upper body). The replaceable part can be detached and replaced with different configurations to provide various customized services, avoiding the need to develop completely separate vehicle bodies for each service type.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The vehicle body configuration is made dynamic through the replaceable part system. Instead of fixed dedicated designs for each service type, the rear upper body can be changed based on service requirements, allowing the same vehicle platform to adapt to different customized services.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a complex replacement system is used to exchange replaceable parts, then the replacement functionality is achieved, but the system complexity increases

Engineering Contradiction:

Improvepart replacement capabilityVSAvoidreplacement system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The replacement system extracts only the essential functions needed for part exchange. The station frame provides positioning, the support frame provides movement along the vehicle's forward-backward direction, and the gripper unit provides gripping and releasing. This minimalistic approach achieves replacement functionality without unnecessary complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The replacement system is designed to enable field replacement operations with simple configuration. The system allows replaceable parts to be exchanged directly at the service location without requiring complex infrastructure or multiple specialized devices.

Inventive Principle:

Principle #25Self-service

3Device complexity

If manual replacement of replaceable parts is performed, then the system configuration remains simple, but the replacement time and labor intensity increase

Engineering Contradiction:

Improvesystem configuration simplicityVSAvoidreplacement time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The gripper unit acts as an intermediary between the operator and the replaceable part. It automatically grips and releases the part, reducing manual labor intensity and replacement time while keeping the overall system configuration relatively simple.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Manual mechanical operations are partially replaced by the automated gripper unit which uses electromagnetic forces for gripping and releasing. This substitution reduces the time and effort required for replacement while maintaining system simplicity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
