Solution Overview

Problem

Access control devices at construction sites face challenges due to uneven and unstable ground, leading to instability, tipping hazards, and unauthorized entry when multiple devices are placed adjacent to each other.

Innovation Solution

A gang clamp assembly comprising first and second brackets with offset legs and fasteners that envelop structural members of adjacent access control devices, securing them together to prevent differential movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple access control devices are placed adjacent to each other on construction sites, then the capacity to control large numbers of persons in a short amount of time is improved, but the stability and safety of the devices deteriorate due to uneven and unstable ground

Engineering Contradiction:
Improvecapacity to control large numbers of personsVSAvoidstability and safety of devices
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent combines multiple access control devices into a single stable structure by coupling them together on a common base. This merging approach allows the devices to share the load and maintain stability on uneven ground while preserving their individual functionality for controlling multiple persons simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a horizontal coupling dimension by connecting adjacent access control devices laterally through a gang clamp assembly. This additional dimensional connection prevents differential movement between devices and stabilizes them against the unstable ground conditions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If access control devices are placed on uneven and unstable ground, then the adaptability to construction site environments is improved, but the stability and safety of the devices deteriorate due to ground shifting and movement

Engineering Contradiction:
Improveadaptability to construction site environmentsVSAvoidstability of devices
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The gang clamp assembly merges multiple devices into a unified stable structure that resists ground movement. By coupling the devices together and to a common base, the system maintains adaptability to construction sites while overcoming the instability of uneven ground.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent employs preliminary anchoring actions by securing devices to a common base before operation. This preliminary stabilization prevents ground shifting from causing device movement during use, thereby maintaining both adaptability and stability.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If mobile access control devices are used on construction sites, then the ease of deployment is improved, but the safety hazards increase due to tipping risks and unauthorized entry from device movement

Engineering Contradiction:
Improveease of deploymentVSAvoidsafety hazards including tipping and unauthorized entry
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent merges multiple devices into a coupled assembly that prevents individual device tipping. This merging maintains the mobile and easily deployable nature of the devices while eliminating safety hazards through mutual stabilization.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The gang clamp assembly acts as an intermediary coupling mechanism between adjacent devices. This intermediary structure prevents direct ground-induced movement from causing tipping or separation, thereby reducing safety hazards while preserving ease of deployment.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A gang clamp assembly for securely coupling a mobile access control device to an adjacent mobile access control device. The clamp assembly includes a first bracket and a second bracket. Each bracket includes a first leg and a second leg separated by an offset. Each bracket is configured to envelop a portion of the exterior surfaces of structural members of the mobile access control devices, such that the offset provides an additional surface against which the structural members can bear. Each bracket includes a first fastener receiving opening in the first leg and a second fastener receiving opening in the second leg. A first fastener is insertable into the first fastener receiving opening in the first leg of the first bracket and the second fastener receiving opening in the second leg of the second bracket.
