Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a traffic signalling pole uses a simple cylindrical pole part with a disc-type base part made of synthetic material, then the device can be produced with reduced cost and simplified manufacturing, but the fixation to the pavement becomes unreliable and complex to install

Engineering Contradiction:
Improvemanufacturing costVSAvoidfixation reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The pole is divided into a pole part and a base part that can be assembled together. The base part includes multiple fixation elements that can be independently adjusted and positioned, allowing reliable fixation to the pavement while maintaining simple manufacturing of each individual component

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base part incorporates adjustable fixation elements that can be positioned and locked at different locations. This dynamic adjustment capability allows the fixation system to adapt to different pavement conditions and installation requirements, providing reliable fixation without complex manufacturing

Inventive Principle:
Principle #15Dynamics

2Reliability

If a traffic signalling pole uses traditional fixation methods, then the pole can be retained on the pavement, but the installation process becomes laborious and time-consuming

Engineering Contradiction:
Improvefixation retentionVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The base part is pre-assembled with multiple fixation elements in specific positions before installation. This preliminary preparation allows for quick installation on-site, reducing installation time while maintaining reliable fixation retention through the pre-positioned fixation elements

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The fixation elements are designed to be self-aligning and self-locking into the pavement. Once positioned, the elements automatically secure the pole without requiring complex manual adjustment or additional tools, significantly reducing installation time while ensuring reliable retention

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If a traffic signalling pole uses a fixed rigid structure, then the pole provides stable signalling, but the pole cannot recover its initial shape after being hit by a vehicle

Engineering Contradiction:
Improvestructural stabilityVSAvoidimpact recovery capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The pole part is designed with controlled flexibility that allows it to bend and deform under impact forces, then return to its original position. This parameter change in rigidity enables the pole to absorb impact energy while maintaining overall structural stability for continued signalling function

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The pole structure incorporates dynamic characteristics that allow it to flex and move in response to external forces such as vehicle impacts. This dynamic behavior enables the pole to recover its initial shape after deformation, providing both stability during normal operation and adaptability during impact events

Inventive Principle:
Principle #15Dynamics
