Unified Radio Remote Control for Construction Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current construction equipment operations require multiple operators due to separate control systems for carriers and attachments, leading to inefficiencies, safety risks, and increased noise and dust challenges, which hinder effective communication and increase operational time.
Innovation Solution
A unified radio remote control system with first and second receivers allows for centralized control of both carrier and attachment devices, enabling single-operator operation by transmitting electrical signals to control movement and functions, regardless of the devices' original control systems, and ensuring compactness and durability against environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate control systems are used for carrier and attachment devices, then each device can be operated independently, but multiple operators are required which increases personnel costs and reduces efficiency
Solution Approach 1:
The patent combines separate control systems for carrier and attachment devices into a unified radio remote control system. The control unit integrates multiple control functions and communicates with both the carrier device and attachment device through wireless communication, allowing a single operator to control the entire system from a remote location, thereby eliminating the need for multiple operators while maintaining independent operation capability.
2Reliability
If multiple operators are deployed for carrier and attachment devices, then operational control is maintained, but safety risks increase due to personnel exposure to danger areas and communication difficulties
Solution Approach 1:
The patent extracts the operator from the dangerous work environment by implementing radio remote control. The control unit is positioned away from the carrier and attachment devices, allowing the operator to control the system from a safe location. This eliminates exposure to harmful factors such as noise, dust, and physical danger areas while maintaining reliable operational control through wireless communication links.
3Loss of information
If operators work in close proximity to equipment for direct control, then communication is possible, but noise and dust make communication difficult and increase health risks
Solution Approach 1:
The patent replaces direct physical communication between operators and equipment with wireless radio communication. The control unit communicates with both the carrier device and attachment device through radio signals, eliminating the need for operators to be in close proximity to the equipment. This substitution resolves communication difficulties caused by noise and dust while removing operators from harmful environmental factors.
4Productivity
If a single operator controls both carrier and attachment devices, then personnel costs are reduced, but the operator must frequently move between locations resulting in time loss
Solution Approach 1:
The patent adds the dimension of spatial separation through radio remote control. Instead of the operator physically moving between the carrier and attachment devices, the control unit remains in one location and wirelessly communicates with both devices. This dimensional change allows a single operator to control multiple devices simultaneously without time loss from movement, while maintaining personnel efficiency.
