Solution Overview

Problem

Existing traffic barricades made of molded plastic are prone to being moved or falling over due to wind or unintentional forces, requiring additional weights for stability, and lack flexibility in design for easy transportation and storage.

Innovation Solution

A collapsible traffic barricade with a retractable T-frame design featuring interchangeable base legs, vertical supports, and chevron boards with reflective material, allowing for easy folding and adjustment to enhance stability, transportation, and storage without compromising durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If molded plastic barricades are used, then damage to vehicles is reduced, but stability against wind and unintentional forces deteriorates

Engineering Contradiction:

Improvevehicle damageVSAvoidbarricade stability

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The barricade is divided into modular components including T-frame base units, vertical supports, and chevron boards that can be assembled and disassembled. This segmentation allows the use of lighter plastic materials while maintaining overall structural stability through proper configuration and interlocking mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The T-frame base incorporates pre-designed stabilization features including recesses for sandbags or weight objects, and a wide base footprint that provides inherent stability before deployment. The reflective chevron boards are pre-attached to vertical supports, ready for immediate assembly.

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If fixed design barricades are used, then structural stability is improved, but ease of transportation and storage deteriorates

Engineering Contradiction:

Improvestructural stabilityVSAvoidtransportation and storage ease

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The barricade transitions from a fixed design to a dynamic, collapsible structure. The T-frame base legs can be folded together, and vertical supports can be detached from chevron boards, allowing the barricade to collapse into a compact configuration for transportation and storage while maintaining structural integrity when deployed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If interchangeable components are used, then adaptability to different traffic situations is improved, but device complexity increases

Engineering Contradiction:

Improvetraffic situation adaptabilityVSAvoidcomponent interchangeability

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The T-frame base units are designed as universal components that can support different configurations of vertical supports and chevron boards. The standardized connection mechanisms allow the same base unit to work with various board types and arrangements, providing adaptability without requiring multiple specialized component sets.

Inventive Principle:

Principle #6Universality (Multi-functionality)
