Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the radiation detector is made larger to image large-diameter pipes, then the imaging capability is improved, but the mechanical stability deteriorates due to increased physical force requirements

Engineering Contradiction:

Improvedetector sizeVSAvoidmechanical stability

Core Design Contradiction:

Area of stationary objectVSStability of the object's composition

Solution Approach 1:

The large radiation detector is divided into multiple smaller detector panels that are arranged in a modular configuration. This segmentation allows each panel to maintain mechanical stability while the overall assembly achieves the required large imaging area through coordinated arrangement of the panels.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The detector employs a composite structure combining flexible substrates with rigid support elements. This composite design enables the detector to maintain mechanical stability under physical force while achieving the necessary large size for imaging large-diameter pipes.

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If the detector is made bendable to conform to pipe surfaces, then the contact quality is improved, but the structural integrity deteriorates

Engineering Contradiction:

Improvecontact qualityVSAvoidstructural integrity

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The detector utilizes flexible substrate materials and thin-film construction that enable bending and conforming to curved pipe surfaces while maintaining sufficient structural integrity. The flexible design allows the detector to adapt to various pipe diameters without compromising the strength of individual detector panels.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If a fixed attachment method is used to secure the detector to the pipe, then the fixation stability is improved, but the risk of damage increases

Engineering Contradiction:

Improvefixation stabilityVSAvoiddamage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The detector replaces traditional mechanical fastening systems with magnetic attachment mechanisms. This substitution provides stable fixation to magnetic steel pipes without the need for physical fasteners that could cause damage, while allowing for easy detachment and repositioning.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The attachment system is designed to be dynamically adjustable, allowing the detector to be securely fixed during operation while enabling easy removal and repositioning. This dynamic capability maintains fixation stability during use while minimizing damage risk through non-permanent attachment.

Inventive Principle:
