Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If vehicle doors are stored on the ground surface, then storage is simple, but the door finish can be damaged

Engineering Contradiction:

Improvesimplicity of storageVSAvoiddamage to door finish

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The rack serves as an intermediary device between the ground and the vehicle door. Instead of placing the door directly on the ground (which causes damage), the rack elevates and supports the door on its horizontal base, preventing contact with the ground surface while maintaining simple storage

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If specialized door storage devices are used, then door protection is improved, but the devices are bulky and lack versatility

Engineering Contradiction:

Improveprotection from damageVSAvoidmultipurpose functionality

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The rack is designed with universal functionality to perform multiple tasks. The horizontal base can hold vehicle doors, the vertical support can hold various items, and the structure can be configured differently for diverse applications. This multi-functionality eliminates the need for specialized single-purpose storage devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The rack is divided into separable components: a horizontal base and a vertical support that can be attached or detached. This segmentation allows the device to be configured for different purposes - holding doors when attached, or serving as a standalone vertical rack when separated, thereby increasing versatility

Inventive Principle:

Principle #1Segmentation

3Object-affected harmful factors

If doors are stored in bulky devices, then door support is provided, but the devices are difficult to move and store

Engineering Contradiction:

Improvedoor support and protectionVSAvoidportability and ease of movement

Core Design Contradiction:

Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The rack incorporates dynamic elements including wheels or casters attached to the horizontal base, enabling easy movement across the ground. The structure can also be collapsed or disassembled, transitioning from an extended protective configuration to a compact stored configuration, making it portable and easy to transport

Inventive Principle:

Principle #15Dynamics

AI summary

A versatile transport rack uses a rectangular shaped horizontal frame and one or more vertical frames that extend upwardly therefrom. Hinge pin receiver pairs are attached to the vertical frame and receive door pin pairs of a vehicle door. Either castors or axle-based wheel sets are removably attached to the horizontal frame in order to move the device about. Plates having appropriately placed templates are attached to the horizontal frame and/or the hinge pin receivers to hold various implements.
