Collapsible A-Frame Barricade with Telescopic Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barricade technologies for vehicular thoroughfares lack a cost-effective, readily collapsible solution that can be easily anchored and secured to prevent unauthorized vehicular access while allowing for easy conversion between barricading and non-barricading configurations.
Innovation Solution
A collapsible barricade apparatus featuring an A-frame upright member with a telescopic support assembly and anchoring means, which includes lock-receiving ring structures to secure the apparatus in an upright position and allow telescopic collapse when unlocked, enabling easy conversion between barricading and non-barricading configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a barricade apparatus is made collapsible for easy storage and transport, then portability is improved, but structural stability during barricading operation may deteriorate
Solution Approach 1:
The barricade apparatus employs a telescopic support assembly that can dynamically change between extended and retracted states. The support assembly includes telescopic members with locking mechanisms that provide structural stability when extended and barricading is needed, while allowing easy collapse when the locking mechanisms are released. This dynamic adaptability resolves the contradiction between collapsibility for portability and structural stability for effective barricading.
2Reliability
If anchoring means is provided to securely fix the barricade to the ground, then reliability of barricading is improved, but device complexity and cost increase
Solution Approach 1:
The anchoring system is segmented into separate anchoring members that can be independently attached to the base of the barricade apparatus. These anchoring members can be individually deployed into the ground or pavement, providing secure fixation without requiring a complex integrated anchoring system. This segmentation reduces overall device complexity while maintaining reliable barricading security.
3Reliability
If lock-receiving ring structures are added to prevent unauthorized movement, then security against unauthorized access is improved, but manufacturing cost increases
Solution Approach 1:
The lock-receiving ring structures are merged with the existing telescopic support assembly and base components. The ring structures serve dual purposes: they provide structural support for the telescopic members and simultaneously serve as locking receptacles for padlocks or other locking mechanisms. This merging of functions reduces the need for separate security components, thereby lowering manufacturing costs while maintaining security against unauthorized access.

AI summary
A collapsible barricade apparatus enables users to selectively barricade space for preventing vehicular traffic to pass therethrough. The barricade apparatus comprises an A-shaped member, a support assembly, and a series of anchor assemblies. The A-shaped member comprises laterally opposed upright sections and inwardly extending, coaxial A-crossbar portions. The A-crossbar portions each comprise an inward terminus. The support assembly comprises two T-shaped sections, one upper and one lower. The T-shaped sections each comprise a shaft end and a T-crossbar end. The shaft ends of the upper and lower section being telescopically cooperable with one another. The T-crossbar end of the upper section is cooperable with the inward termini for coaxially aligning and rotatably connecting the upper section to the inwardly extending A-crossbar portions. The anchor assemblies rotatably anchor the feet of the A-shaped member and the lower section of the support assembly to a primary support surface.
