Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bridge construction methods require precise placement of foam strips between beams, which is labor-intensive and risky, especially when working at heights, and lacks accuracy due to potential errors in beam positioning.
Innovation Solution
A motorized construction robot with a geo-positioning system and height-adjustable cutting tools that runs along the beams to precisely place and cut high-density foam strips, ensuring accurate slab positioning by comparing real-time with theoretical positions and adjusting the foam height accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If workers manually place foam strips between beams, then the foam strips can be precisely positioned, but the labor intensity and risk of accidents increase significantly
Solution Approach 1:
The robot performs foam strip placement and cutting operations autonomously without human intervention. The system uses its own sensors to detect beam positions, calculates required foam strip dimensions, and executes placement and cutting operations automatically, eliminating the need for workers to manually handle foam strips at heights.
Solution Approach 2:
The patent replaces the manual mechanical system of workers placing and cutting foam strips with an automated robotic system. The robot uses mechanical arms for placement, heated wires for cutting, and integrated sensors for detection, substituting human labor with an automated electromechanical system that reduces accident risk while maintaining precision.
2Manufacturing precision
If foam strips are placed precisely according to beam positions, then slab positioning accuracy improves, but construction time increases due to manual measurement and cutting
Solution Approach 1:
The robot performs foam strip placement and cutting operations in a continuous automated sequence without interruption. The system moves from one beam position to the next continuously, detecting, placing, and cutting foam strips without the stops and manual repositioning required in traditional methods, thereby improving construction speed while maintaining precision.
Solution Approach 2:
The robot pre-calculates the exact position and dimensions of foam strips needed based on detected beam locations before actual placement. This preliminary planning allows the robot to execute placement and cutting operations efficiently without delays for measurement and calculation during the construction process.
3Manufacturing precision
If the robot adjusts foam strip height based on real-time position detection, then slab positioning accuracy improves, but the system complexity increases
Solution Approach 1:
The robot uses sensors to detect the actual position of beams, compares this with the theoretical position, calculates the deviation, and automatically adjusts foam strip placement and cutting operations to compensate for the deviation. This closed-loop feedback system ensures accurate slab positioning despite variations in beam placement.
Solution Approach 2:
The robot integrates multiple functions into a single system: beam position detection, foam strip placement, height adjustment, and cutting operations. This multi-functional design reduces the need for separate equipment and manual operations, managing system complexity while achieving precise slab positioning through automated coordinate adjustments.
