Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional concrete methods are used to produce road kerbs and edgings, then structural strength and durability are achieved, but the production process becomes complex, costly, and time-consuming with significant environmental impact

Engineering Contradiction:
Improvestructural strengthVSAvoidproduction process complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The invention changes the material parameters from traditional concrete to elastomeric asphalt conglomerate, which allows the material to be applied in a viscous state and then solidify, eliminating the need for complex formworks, steel reinforcement, and multi-step concrete pouring processes while maintaining structural strength

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses a composite material composition consisting of elastomeric material (such as rubber granulates) combined with asphalt binder, creating an elastomeric asphalt conglomerate that provides both structural integrity and flexibility, resolving the contradiction between strength and process simplicity

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If traditional concrete methods are used to produce road kerbs and edgings, then structural stability is achieved, but installation time and traffic disruption increase

Engineering Contradiction:
Improvestructural stabilityVSAvoidinstallation time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The elastomeric asphalt conglomerate is prepared in advance in a viscous state, allowing it to be directly applied to the road surface and immediately form a stable structure upon solidification, eliminating the lengthy curing time required for concrete while maintaining structural stability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention utilizes the phase transition of the elastomeric asphalt conglomerate from a viscous liquid state during application to a solid state upon cooling, enabling rapid installation without formworks and with immediate structural stability, significantly reducing installation time compared to concrete methods

Inventive Principle:
Principle #36Phase transitions

3Duration of action of stationary object

If traditional concrete methods are used to produce road kerbs and edgings, then material durability is achieved, but environmental impact and disposal costs increase

Engineering Contradiction:
Improvematerial durabilityVSAvoidenvironmental impact
Core Design Contradiction:
Duration of action of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The invention employs asphalt material that can be easily removed and reused or recycled, eliminating the need for complex concrete separation processes and reducing disposal costs, while the elastomeric components can also be recovered and reused, significantly reducing environmental impact

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The invention converts the typically harmful asphalt material, which requires disposal when removed, into a beneficial reusable resource by combining it with elastomeric material, creating a composite that maintains durability while enabling easy recovery and recycling, thus reducing environmental impact

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
