Rotary Control Box for Aerial Work Platform Ground Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerial work platforms face inefficiencies and safety issues due to the need for operators to stand on the platform or in a cab to control the device, leading to obstructed sight, repeated actions, and exposure of the control device to dust and space constraints.
Innovation Solution
A vehicle with a rotary control box mounted on a lateral side of the frame, allowing operators to control the aerial work platform from the ground, featuring a hinged control box that can be locked within a casing for protection and space efficiency, and an electrically connected telescopic transmission component for precise motion control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control device is disposed on the operation platform, then the operator can control the platform directly, but the operator must stand on the platform which causes safety issues and obstructed sight
Solution Approach 1:
The control device is extracted from the operation platform and relocated to the ground level, allowing the operator to control the platform from a safe position on the ground while maintaining control accessibility through the extended control arm mechanism
2Ease of operation
If the control device is mounted in the cab, then the operator is protected from elements, but the operator's sight is obstructed and blind areas are formed
Solution Approach 1:
The control device is extracted from the enclosed cab space and positioned on the ground where the operator has unobstructed visual access to the operation platform and surrounding environment, eliminating blind areas while maintaining operator protection through the enclosed control box design
3Ease of operation
If the control device is fixedly mounted on the turret, then the operator can control from ground level, but the operator must adjust location frequently as the turret rotates
Solution Approach 1:
An extendable control arm mechanism serves as an intermediary between the rotating turret and the control device, allowing the control box to remain stationary on the ground while the control arm extends and retracts to maintain optimal positioning relative to the rotating platform, eliminating the need for operator repositioning
4Ease of operation
If the control device is exposed, then it is accessible for operation, but the control device is exposed to dust and aging
Solution Approach 1:
The control device is enclosed in a protective control box with a hinged lid that can be opened for operation and closed for protection, creating a flexible barrier that shields the control device from dust and environmental factors while maintaining accessibility during use
5Ease of operation
If the control device occupies large area when idle, then it is accessible, but it causes inconvenience and poor appearance
Solution Approach 1:
The control box is designed to nest within or adjacent to the vehicle structure when not in use, minimizing the space occupied by the control device during idle periods while maintaining full accessibility when operation is required
