Demolition Robot Control Lever Mode Switching for Smooth Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote-controlled demolition robots experience inefficient operation due to the need to release control levers to switch between different operating modes, leading to jerky and erratic movements.
Innovation Solution
Incorporation of a secondary operating mode selector switch on the control lever, allowing operators to switch between modes without releasing their grip, enabling momentary activation of alternative operating modes for smoother and more efficient control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operating mode selector switch is located on the remote control unit, then the operator can switch between different operating modes, but the operator must release grip from the control lever which causes time loss and jerky movements
Solution Approach 1:
The patent moves the operating mode selector switch from the remote control unit to the control lever itself, changing the spatial dimension of the switch location. This allows the operator to access the switch while maintaining grip on the control lever, eliminating the need to release grip and reducing switching time.
Solution Approach 2:
The control lever acts as an intermediary element that integrates both the mode selector switch and the control function. By placing the switch on the lever, the system allows mode switching to occur during normal control operations without interrupting the operator's grip or control flow.
2Adaptability or versatility
If the operating mode selector switch is located on the remote control unit, then mode switching is possible, but the operator cannot perform movements in efficient sequential order
Solution Approach 1:
By relocating the mode selector switch to the control lever, the patent enables mode switching to occur within the same spatial context as control operations. This allows operators to switch modes and execute movements in efficient sequential order without breaking their operational flow.
Solution Approach 2:
The integration of the mode selector switch on the control lever enables continuous operation without interruption. Operators can switch modes and continue controlling movements seamlessly, maintaining the continuity of useful action and improving overall productivity.
3Adaptability or versatility
If the operating mode selector switch is on the remote control unit, then all control options are accessible, but the control operation becomes complex and time-consuming
Solution Approach 1:
The patent relocates the mode selector switch from the remote control unit to the control lever, changing the spatial arrangement to improve ease of operation. This allows operators to access all control options including mode switching while maintaining a simple, intuitive control flow without complex hand movements.

AI summary
A remote-controlled demolition robot includes a control unit, an undercarriage with propulsion means, an upper carriage with a maneuverable arm means and a remote control unit having a first and second control lever and an operating mode control switch to switch between alternative operating modes, the remote control unit to give commands via the operating mode control switch to control the robot in alternative operating modes by the control levers. The operating mode selector switch can form a primary operating mode control switch and one control lever can have a secondary operating mode control switch accessible for activation without releasing a grip on the control lever and, when activated, momentarily switches the control unit from the operating mode dedicated by the primary operating mode selector switch to an alternative momentary operating mode, the switching being active as long as the secondary operating mode control switch is activated.
