Flexible Dump Bucket Liner for Complete Debris Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dump devices, such as bucket systems for backhoes, lack a liner to prevent debris buildup and ensure complete emptying, leading to inefficiencies and maintenance issues.
Innovation Solution
A flexible panel with loose connection edges is mounted inside the bucket, extending between the sides and coupled with restraint assemblies and beams, allowing it to conform to the interior surface when the bucket is full and detach when dumping, aided by vibration members to dislodge debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a rigid liner is attached to the bucket interior, then debris buildup is prevented, but complete emptying becomes difficult due to material adherence
Solution Approach 1:
The liner is designed with loose connection edges that allow it to transition from a static conforming state during loading to a dynamic detached state during dumping. This dynamic behavior enables the liner to prevent debris buildup while allowing complete emptying by detaching and carrying materials away from the bucket interior.
Solution Approach 2:
The liner's connection state changes from fixed to loose during the dumping cycle. The loose connection edges allow the liner to change its position and orientation parameters, enabling it to fall away from the concave interior surface and effectively change from a containment structure to a transport medium that carries materials out of the bucket.
2Object-affected harmful factors
If a flexible panel is used to line the bucket, then the panel conforms to the interior surface and prevents debris buildup, but the panel may not detach completely during dumping
Solution Approach 1:
The liner is divided into multiple panels with loose connection edges rather than being a single continuous piece. This segmentation allows each panel to independently detach and fall away from the bucket interior during dumping, ensuring complete separation and preventing any single panel from remaining attached and causing incomplete emptying.
Solution Approach 2:
The loose connection edges act as intermediaries between the liner and the bucket interior. These edges allow the liner to maintain contact during loading (preventing debris buildup) while enabling complete detachment during dumping (ensuring reliable separation). The intermediary connection mechanism resolves the contradiction between adherence and detachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents debris buildup and ensures complete emptying of the bucket by allowing the panel to detach and carry away substances, reducing maintenance and improving operational efficiency.
Implementation Method 1
The panel is flexible such that the panel extends into and conforms to the concave interior surface of the bucket when the bucket is in the holding position
Implementation Method 2
the panel falls away from the concave interior surface of the bucket when the bucket is moved into either of the first and second dumping positions
Implementation Method 3
aided by vibration members to dislodge debris

AI summary
A dump liner system includes a bucket which may contain a substance when positioned in a holding position such that a concave interior surface of the bucket faces generally upwardly. The bucket may be turned in either of a first rotational direction or an opposing second rotational direction to dump the substance. A flexible panel is mounted in the bucket and acts as a liner which conforms to the concave interior surface of the bucket when the bucket is in the holding position. The flexible panel is tethered to the bucket but otherwise free to move. The flexible panel falls out of the bucket via 10 gravity when the bucket dumps the substance contained therein, which helps facilitate removal of the substance which would otherwise stick to the concave interior substance.
