Solution Overview

Problem

Existing methods for assembling cargo spaces in commercial vehicles are costly and complex, particularly in terms of forming enclosed spaces that protect against external weather influences.

Innovation Solution

A modular kit comprising base and intermediate modules that can be snapped, screwed, or connected via fasteners to form enclosed cargo spaces, with options for adjustable dimensions and weather-resistant seals, allowing flexibility in assembly and adaptation to various chassis lengths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional methods are used to assemble cargo spaces, then enclosed weather-protected spaces can be formed, but the assembly process becomes costly and complex

Engineering Contradiction:

Improveweather protectionVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The cargo space is divided into modular components (side walls, front wall, rear wall, floor, ceiling) that can be assembled independently and then connected. This segmentation allows for simplified manufacturing and assembly while maintaining the enclosed weather-protected space functionality.

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If custom cargo spaces are manufactured for each chassis, then precise fit and weather protection are achieved, but costs and manufacturing complexity increase

Engineering Contradiction:

Improvecargo space fitVSAvoidmanufacturing cost

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The modular components are designed with standardized connection elements that allow the same set of modules to be configured for different chassis types and cargo space requirements. This universality reduces manufacturing costs through economies of scale while maintaining precise fit through adaptable assembly configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The kit allows for dynamic configuration of the cargo space by selecting and arranging different modules based on the specific chassis dimensions and requirements. This dynamic adaptability enables a single kit design to serve multiple applications without requiring custom manufacturing for each case.

Inventive Principle:

Principle #15Dynamics

3Ease of manufacture

If fixed-dimension cargo spaces are used, then manufacturing is simpler, but adaptability to different chassis lengths is reduced

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidchassis adaptation

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The cargo space is segmented into multiple modular components that can be arranged in different configurations. This segmentation enables the same set of modules to create cargo spaces of varying lengths and dimensions, adapting to different chassis while maintaining manufacturing simplicity through standardized module designs.

Inventive Principle:

Principle #1Segmentation
