Solution Overview

Problem

Existing motor vehicles, particularly commercial and professional vehicles like vans and refrigerated vehicles, lack dedicated storage spaces for mandatory equipment items such as tools or safety vests, which can be cumbersome, lost, or forgotten, and are not suitable for vehicles without trunks that are already space-constrained.

Innovation Solution

A motor vehicle design featuring a side panel with an oblong vertical opening leading to a storage cavity for equipment, equipped with a retaining tab and optional decorative trim, which allows easy access and secure storage without occupying existing storage space, using a locking system and vibration-absorbing materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a motor vehicle is equipped with additional functional items (charging device, cooling device, heating device), then the functionality and comfort for motor cycle riders is improved, but the available stowage space becomes insufficient

Engineering Contradiction:
ImprovefunctionalityVSAvoidstowage space
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The charging device, cooling device, and heating device are nested within the opening panel structure. Specifically, the charging device is integrated into the opening panel, the cooling device is arranged in the recess, and the heating device is integrated into the opening panel, allowing multiple functional items to occupy the same spatial envelope without increasing overall vehicle volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The opening panel serves multiple functions: it acts as a structural component of the vehicle body, provides stowage space for equipment articles, houses the charging device, and integrates the heating device. The recess serves as both a structural feature and a housing for the cooling device, demonstrating multi-functionality that resolves the space-constraint problem.

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

2Productivity

If equipment articles are stowed in the opening panel, then stowage capability is improved, but access to the stowage cavity becomes difficult when the saddle is mounted on the vehicle

Engineering Contradiction:
Improvestowage capabilityVSAvoidaccess to stowage cavity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The opening panel is segmented into multiple independent opening sections (first opening section and second opening section) that can be opened separately. This segmentation allows users to access specific stowage cavities without needing to remove the entire saddle or open all sections, significantly improving ease of access while maintaining stowage capability.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the opening panel is designed to accommodate various equipment articles, then versatility is improved, but the structural complexity increases

Engineering Contradiction:
Improveaccommodation capabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The opening panel is designed as a universal structure that accommodates multiple types of equipment articles (charging device, cooling device, heating device) through standardized integration points. The panel's universal design allows different functional items to be mounted without requiring structural modifications, thereby avoiding increased complexity while maintaining versatility.

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