Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The laser receiver in work machines may fail to receive the laser beam due to blocking by attachments or deviation from the projection range, leading to poor work efficiency.
Innovation Solution
A work system with a laser projector and a work machine equipped with a laser receiver, a position detection unit, and a range setting unit that sets an allowable operation range to maintain laser beam reception, using a controller to manage the work machine's operation within these ranges.

Engineering Contradiction Analysis
1Productivity
If the work machine operates freely without range restrictions, then the work efficiency is improved through flexible operation, but the laser receiver may be blocked by attachments or deviate from the projection range, requiring work interruptions to re-establish beam reception
Solution Approach 1:
The range setting unit pre-calculates and sets the allowable operation range based on the current relative position between the laser receiver and laser projector, and the attachment's potential blocking positions. This preliminary action establishes preventive boundaries before blocking occurs, allowing the operator to work continuously within the predefined safe range without interruptions for re-establishing beam reception.
Solution Approach 2:
The position detection unit continuously monitors the relative position between the laser receiver and laser projector, providing real-time feedback to the range setting unit. This feedback loop enables dynamic adjustment of the allowable operation range as the machine moves, ensuring the receiver remains within the projection range while maintaining flexible operation for high productivity.
2Reliability
If the allowable operation range is set based on real-time position detection, then the laser receiver maintains continuous beam reception, but the system complexity increases due to additional detection and calculation units
Solution Approach 1:
The controller of the work machine is designed to perform multiple functions: it controls the attachment's operation, processes position detection data, calculates the allowable operation range, and provides guidance to the operator. By making the controller multi-functional, the patent avoids adding separate dedicated units for each function, thereby maintaining reliability through continuous monitoring while minimizing the increase in system complexity.
