Flexible Dump Bucket Liner for Complete Material Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dump devices lack a liner to prevent debris retention and buildup in buckets or tubs during material dumping.
Innovation Solution
A flexible panel is coupled to the high side of a receptacle, conforming to its interior surface and gravitationally urged away during dumping to facilitate material discharge, with a connection edge attached to the receptacle and a flexible lining that avoids crevices for debris sticking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid liner is attached to the receptacle interior, then material retention is prevented, but complete emptying is hindered due to material sticking to the liner
Solution Approach 1:
The liner is designed as a flexible, movable component rather than a rigid fixed structure. The liner can dynamically change its position and conformality - being substantially conformal during loading to prevent debris buildup, and becoming disengaged or detached during dumping to enable complete material emptying. This dynamic adaptability resolves the contradiction between preventing retention and ensuring complete emptying.
2Productivity
If a flexible panel is unconnected to the receptacle, then complete emptying is achieved, but debris buildup prevention is reduced
Solution Approach 1:
The flexible panel's connection status is dynamic rather than static. The panel can be substantially conformal to the receptacle interior surface when needed for debris prevention, and can be disengaged or detached when complete emptying is required. This dynamic behavior allows the system to achieve both contradictory goals at different operational stages.
3Ease of operation
If the receptacle interior is smooth for easy cleaning, then material sticking is reduced, but debris buildup occurs due to lack of structural support
Solution Approach 1:
The receptacle interior is segmented into two functional components: the fixed receptacle structure providing structural support, and the separate flexible liner providing a smooth non-sticking surface. This segmentation allows each component to independently perform its optimized function - the receptacle maintains structural integrity while the liner provides easy-cleaning properties and debris prevention through its conformal fit.
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 receptacle by allowing material to be easily discharged, enhancing operational efficiency.
Implementation Method 1
the panel is unconnected to the receptacle except along the high side such that the panel is gravitationally urged away from the interior surface of the receptacle in the dumping position to facilitate dumping of the material from the receptacle

AI summary
A dump liner device includes a receptacle, such as a bucket of a digger, having a high side and a low side when in a dumping position. The receptacle has a concave interior surface for holding material in the receptacle while in a holding position. A connection edge of a flexible panel is coupled to the high side of the receptacle. The panel conforms to the interior surface of the receptacle but is unconnected to the receptacle except along the high side such that the panel is gravitationally urged away from the interior surface of the receptacle in the dumping position to facilitate dumping of the material from the receptacle as the receptacle is moved into the dumping position from the holding position.
