Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete/steel disassembling devices have limited range of operation due to their reliance on remote power sources and rigid connections, which restricts their use on tall structures and can cause damage to equipment, and are difficult to maneuver due to lack of visibility.
Innovation Solution
A self-powered concrete/steel structure disassembling apparatus with an integrated hydraulic power source and radio control operation, equipped with pivotable tools and a camera for improved engagement and visibility, allowing for remote control and adjustment of the center of gravity for enhanced operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the disassembling device is fixed to the end of a mechanical arm or boom with rigid connection, then the device can be supported and positioned, but the forces and torques from the weight of removed structures cause damage to the mechanical equipment and limit work capacity
Solution Approach 1:
The invention extracts the power source from the base equipment and integrates it into the disassembling device itself. The self-contained hydraulic power unit and engine are mounted on the disassembling device, allowing it to operate independently without being mechanically supported by a boom or arm, thereby eliminating the harmful forces and torques on the supporting equipment.
Solution Approach 2:
The disassembling device serves itself by incorporating its own power source and hydraulic system. The engine drives the hydraulic pump which powers all hydraulic components including the pulverizer, shearer, and positioning systems, making the device self-sufficient and eliminating dependence on external mechanical support structures.
2Use of energy by moving object
If the disassembling device is connected to a remote power source via hydraulic lines, then operating power can be supplied, but the reach and range of operation are limited by the length of the mechanical arm or boom
Solution Approach 1:
The invention extracts the power source from the remote base equipment and relocates it directly to the disassembling device. This eliminates the need for hydraulic lines and mechanical arms, allowing the device to reach any location within the crane's suspension range without being constrained by arm length.
Solution Approach 2:
The invention uses a wireless remote control system as an intermediary between the operator and the disassembling device. The radio control receiver and transmitter enable the operator to control the device from a distance without physical connection, while the self-contained power system enables the device to operate independently at any position within range.
3Ease of operation
If the disassembling device is fixed to a mechanical arm, then the device can be positioned and supported, but the operator has difficulty maneuvering the device due to lack of visibility
Solution Approach 1:
The invention incorporates cameras and display devices that provide visual feedback to the operator. The camera captures images of the work area and transmits them to the display device, allowing the operator to see the disassembling device and structure clearly even when out of direct visual range, thereby improving maneuverability and visibility.
4Power
If hydraulic power is delivered via hydraulic lines from a remote pump, then the disassembling device can be powered, but additional power delivery requirements increase system complexity
Solution Approach 1:
The invention merges the power source (engine), power generation system (hydraulic pump), and power distribution system (hydraulic lines and valves) into a single integrated unit mounted on the disassembling device. This consolidation eliminates the need for separate remote power sources and long hydraulic lines, reducing overall system complexity while providing all necessary hydraulic power locally.
