Excavator Bucket Adjustment Timing Display for Accurate Digging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shovels with machine guidance functions face challenges in determining when bucket adjustments are necessary, leading to increased man-hours and inaccurate excavation due to improper timing of adjustments.
Innovation Solution
A shovel equipped with a display device that shows time information for the last adjustment of the working part, allowing operators to adjust the bucket at appropriate times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator adjusts the bucket without time information guidance, then the operator may adjust the bucket when not necessary or fail to adjust when necessary, but this leads to increased man-hours and decreased excavation accuracy
Solution Approach 1:
The display device provides feedback to the operator by showing time information about the last bucket adjustment, enabling the operator to make informed decisions about when adjustment is needed, thus preventing both unnecessary adjustments and missed adjustments
Solution Approach 2:
The system performs preliminary recording of adjustment time information, so that when the operator needs to decide whether to adjust the bucket, the relevant time data is already available and presented, eliminating the need for manual tracking or estimation
2Manufacturing precision
If the operator frequently checks and adjusts the bucket, then excavation accuracy may be maintained, but this increases operational time and reduces productivity
Solution Approach 1:
Instead of continuous monitoring or frequent manual checks, the system uses periodic adjustment based on recorded time intervals, allowing the operator to maintain excavation precision while minimizing interruptions to productive work
