Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable barriers for vehicle access control are complex and time-consuming to install, and traditional concrete barriers pose safety risks when vehicles collide with them, especially for temporary use in areas like crowded events.
Innovation Solution
A lightweight (15-100 kg) steel or iron-based barrier module with a triangle-shaped base and adjustable post ratio, designed for easy setup without machinery, featuring a hollow post for reduced material costs and enhanced transportability, and a securing wire system to maintain stability and slow vehicle impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy concrete barriers are used to block vehicles, then the barrier provides strong stopping power, but the barrier cannot be easily moved and causes serious accidents when vehicles collide with it
Solution Approach 1:
The barrier system is divided into multiple individual barrier modules that can be separately positioned and moved. Each module is a self-contained unit with a post and base that can be independently deployed and relocated, allowing the entire barrier system to be easily reconfigured without moving heavy concrete structures.
Solution Approach 2:
The barrier modules use adjustable parameters such as post height (500-1200 mm) and base side lengths (400-1000 mm) to optimize both strength and portability. The weight range (15-100 kg) is carefully controlled to provide sufficient stopping power while remaining manually movable, resolving the contradiction between strength and ease of operation.
2Reliability
If complex movable barrier structures are used to control vehicle flow, then the barrier provides effective access control, but the installation becomes time-consuming
Solution Approach 1:
The barrier system consists of standardized modular units that can be quickly assembled and deployed. Each module is pre-fabricated with integrated components (post, base, securing means), eliminating the need for complex on-site construction and reducing installation time while maintaining effective access control.
Solution Approach 2:
The barrier modules are pre-assembled with all necessary components attached before deployment. The securing means are pre-positioned on each module, allowing for rapid installation by simply connecting the pre-prepared units together, significantly reducing setup time compared to complex barrier systems requiring on-site assembly.
3Strength
If traditional concrete barriers are used to stop vehicles, then the barrier provides immediate stopping power, but vehicles running into them are immediately brought to a complete stop causing serious casualties
Solution Approach 1:
The barrier modules are designed to be dynamic rather than rigidly fixed. Upon vehicle impact, the modules can tip over or be pushed back, allowing the vehicle to slow down progressively rather than being abruptly stopped. This dynamic response reduces impact forces and prevents serious casualties while maintaining effective vehicle flow control.
Solution Approach 2:
The barrier system converts the harmful abrupt stopping force into a beneficial progressive deceleration mechanism. By allowing the barriers to move and tip upon impact, the system transforms what would be a dangerous sudden stop into a controlled energy dissipation process that protects vehicle occupants while still achieving vehicle stopping.
4Strength
If solid post barriers are used to provide structural strength, then the barrier provides robust protection, but the material costs and transport difficulty increase
Solution Approach 1:
The barrier post is designed as a hollow structure rather than solid, reducing material usage and weight (15-100 kg per module) while maintaining sufficient structural strength through optimized wall thickness and geometry. The hollow design facilitates easier transportation and handling without significantly compromising the barrier's ability to perform its vehicle control function.
