Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for aligning the laying arm of a bridge-laying vehicle with a bridge element are time-consuming and require manual intervention, especially in limited visibility conditions, posing risks to crew members in military applications.
Innovation Solution
Equipping the bridge-laying vehicle with a detection device, such as a thermal imaging camera or laser scanner, to automatically detect the position of the bridge element and provide alignment instructions to the driver, allowing for remote control and automatic alignment of the laying arm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual alignment method is used, then the driver can position the vehicle, but the process is time-consuming and requires crew members to be exposed in hazardous environments
Solution Approach 1:
The patent replaces the manual mechanical alignment process with an automated optical detection system. A detection device with camera and laser scanner automatically detects the bridge element's position and provides alignment instructions to the driver, eliminating the need for crew members to manually position the vehicle and reducing alignment time while improving safety.
2Productivity
If the driver manually positions the vehicle, then alignment can be achieved, but visibility limitations require multiple attempts and delay the operation
Solution Approach 1:
The patent introduces a detection device as an intermediary between the driver and the bridge element. The device includes a camera for visual detection and a laser scanner for precise position measurement, which together provide the driver with accurate alignment instructions, eliminating the need for multiple trial attempts and improving both productivity and ease of operation.
3Measurement precision
If another crew member dismounts to instruct the driver, then alignment can be achieved, but this delays the pickup and exposes the crew member to danger
Solution Approach 1:
The patent enables the bridge-laying vehicle to perform self-alignment through an integrated detection device. The vehicle's own detection system automatically measures the bridge element's position and provides alignment guidance to the driver, eliminating the need for another crew member to dismount and instruct, thereby maintaining measurement precision while reducing operational complexity and safety risks.
