Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The coordination between construction machines and transport vehicles during loading and unloading is hindered by inadequate communication, leading to issues such as uneven distribution of bulk material, potential collisions, and inaccurate estimation of load weight, which compromises traffic safety and efficiency.
Innovation Solution
A system comprising an image-recording device mounted on the construction machine aligned towards the transport vehicle's loading space, transmitting data to a reception and display device in the transport vehicle, allowing for real-time monitoring and control of the loading and unloading processes through image streams and additional data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator of the construction machine uses audible signals (horn alerts) to communicate with the driver of the transport vehicle, then the driver can be alerted to stop or start driving, but the driver may fail to hear the horn alert or be misled by other vehicles' horn alerts
Solution Approach 1:
The patent replaces the acoustic communication system (horn alerts) with an optical communication system (image-recording device transmitting visual images to a display device). This substitution eliminates the problems of audible signals being inaudible or misleading, as visual information provides direct, unambiguous feedback about the loading space status and material distribution to the transport vehicle driver.
Solution Approach 2:
The patent introduces an image-recording device and display device as intermediaries between the construction machine operator and the transport vehicle driver. These devices serve as a reliable communication channel that translates the operator's observations into visual information that the driver can directly perceive and act upon, eliminating the need for ambiguous audible signals.
2Manufacturing precision
If the operator of the construction machine manually monitors and signals the driver of the transport vehicle to stop and start driving, then the loading process can be controlled, but the operator needs to muster a high level of concentration for the primary operation of the machine
Solution Approach 1:
The patent enables the transport vehicle driver to independently monitor the loading space and material distribution through the display device, allowing the driver to self-regulate the vehicle's movement without requiring continuous attention from the construction machine operator. The operator can focus on the primary milling operation while the visual system handles the coordination.
Solution Approach 2:
The patent implements a visual feedback loop where the image-recording device continuously captures images of the loading space and transmits them to the display device in the transport vehicle. This real-time feedback enables the driver to see the material distribution and loading progress, allowing for precise control of the loading process without increasing operator workload.
3Productivity
If the transport vehicle moves forward continuously while the construction machine discharges material, then the loading process is efficient, but the point of discharge travels from the front towards the rear making uniform distribution difficult
Solution Approach 1:
The patent uses the image-recording device to provide real-time visual feedback about the material distribution and the position of the discharge point relative to the loading space. This feedback enables the transport vehicle driver to adjust the vehicle's speed and position to maintain optimal loading conditions, ensuring uniform material distribution while maintaining continuous forward movement.
