Excavation Bucket Target Penetration Depth Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inexperienced operators using hydraulic excavators face challenges in maintaining accurate excavation depth due to the inefficiency of conventional penetration depth indicators, which are often obscured by soil and difficult to see, leading to inefficient excavation work.
Innovation Solution
The excavation bucket design incorporates a target penetration depth display component positioned on the side wall parts, near the cutting blade, which is easily visible and provides a clear indication of the desired penetration depth, reducing soil adherence and improving visibility, allowing operators to excavate efficiently regardless of experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the indicator piece sticks out from the side wall of the excavation bucket, then the penetration depth can be indicated, but soil adheres to the indicator piece making it difficult to see
Solution Approach 1:
Instead of making the indicator stick out from the side wall (external indication), the patent inverts the approach by providing the target penetration depth display component on the inner surface of the side wall. This internal display position prevents soil adhesion while maintaining visibility for the operator, thus resolving the contradiction between indication functionality and visibility.
2Measurement precision
If the indicator piece is positioned on the side wall, then penetration depth can be marked, but it is obscured by soil during excavation work
Solution Approach 1:
The patent applies inversion by placing the depth display component on the inner surface of the side wall rather than on the outer surface. This positional inversion eliminates direct contact with soil during excavation, preventing soil adhesion and maintaining clear visibility of the penetration depth markings throughout the excavation process.
3Manufacturing precision
If conventional indicators are used, then depth marking is possible, but inexperienced operators cannot maintain accurate depth control
Solution Approach 1:
The patent implements feedback by providing continuous visual indication of the target penetration depth through the display component on the inner side wall. This allows operators to constantly monitor and adjust the excavation depth in real-time, receiving immediate visual feedback on whether they are achieving the desired penetration depth, thereby improving depth control accuracy for operators of all experience levels.

AI summary
An excavation bucket includes a bottom face part, a rear face part, a pair of opposing side wall parts, teeth, a bracket, and a target penetration depth display component. The target penetration depth display component is provided around the teeth and near an end of the side wall part that forms an edge of an opening, and displays the target penetration depth. A wrist radius is an imaginary line segment connecting a center of a first hole in the bracket and the distal end of the teeth in side view. The target penetration depth display component is provided to an inside of at least one of the pair of opposing side wall parts and at a position of the side wall part corresponding to a position that has moved along the imaginary line segment from the distal end of the teeth by a specific proportional length of the wrist radius.
