Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If foam block wall panels are used to form barrier walls, then the barrier wall is light and easy to construct, but the wall panels are weak and unable to stop moving vehicles

Engineering Contradiction:
Improveease of constructionVSAvoidstrength to stop vehicles
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent combines foam blocks with concrete to create a composite barrier wall structure. The foam blocks provide lightweight insulation and noise reduction properties, while the concrete provides structural strength to stop vehicles. This composite approach resolves the contradiction by integrating materials with complementary properties.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The barrier wall is divided into modular segments where foam blocks are placed between concrete sections. This segmentation allows the lightweight foam components to be easily handled and installed while the concrete segments provide the necessary structural strength. The modular design maintains ease of construction while achieving vehicle-stopping capability.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If foam block wall panels are used to form barrier walls, then the barrier wall is easy to construct, but the wall panels do not offer sufficient sound dampening capabilities

Engineering Contradiction:
Improveease of constructionVSAvoidnoise propagation
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The combination of foam blocks and concrete creates a composite structure with improved sound dampening properties. The foam material provides acoustic insulation while the concrete adds mass and structural integrity, together achieving sufficient noise reduction to meet modern standards while maintaining ease of construction.

Inventive Principle:
Principle #40Composite materials

3Device complexity

If foam block wall panels are not attached to supports, then the barrier wall is simple to assemble, but the wall panels may be knocked loose by vehicle impact and cause damage or injury

Engineering Contradiction:
Improveassembly simplicityVSAvoidpanel attachment security
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The concrete portions of the composite barrier wall provide inherent attachment security to the supports. The concrete's weight and structural integrity ensure panels remain securely attached during vehicle impact, eliminating the need for additional attachment mechanisms while maintaining assembly simplicity.

Inventive Principle:
Principle #40Composite materials
