Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the support body is made from padded metal frame or foam material to ensure stability and safety, then the structural strength and reliability are improved, but the volume and weight increase making it bulky and difficult to transport

Engineering Contradiction:
ImprovestabilityVSAvoidvolume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The support body uses inflatable elements filled with gas to create a rigid-like structure when inflated. The gas pressure maintains the shape and provides structural support, allowing the device to be compact when deflated and stable when inflated, thus resolving the contradiction between volume and reliability

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The support body changes its physical state from deflated (compact) to inflated (expanded) to alter its volume and structural properties. This parameter change allows the same structure to provide stability when needed while minimizing volume for transport, resolving the contradiction between reliability and volume

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the support body is made from padded metal frame or foam material to ensure stability and safety, then the structural strength and reliability are improved, but the weight increases making it difficult to handle

Engineering Contradiction:
ImprovestabilityVSAvoidweight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The support body replaces heavy solid materials (metal frame, foam) with lightweight inflatable elements. The gas-filled structure provides the necessary rigidity and support with minimal weight, resolving the contradiction between reliability and weight

Inventive Principle:
Principle #29Pneumatics and hydraulics

Solution Approach 2:

The support body uses thin flexible membranes that form inflatable elements. These thin films provide the necessary containment and structural definition when inflated, creating a lightweight yet stable structure that resolves the contradiction between weight and reliability

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If the side elements project elongated from the back element to prevent lateral slippage, then the reliability of positioning is improved, but the volume increases making it bulky

Engineering Contradiction:
Improvepositioning accuracyVSAvoidvolume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The side elements are inflatable structures that expand to provide lateral support and prevent slippage when inflated, while collapsing to minimal volume when deflated. This resolves the contradiction between positioning accuracy and volume by using gas pressure to create the necessary structural extension only when needed

Inventive Principle:
Principle #29Pneumatics and hydraulics
