Foldable Large Load Carrier With Hopper Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large load carriers are excessively heavy when empty, making manual handling impossible, and current designs require complex stiffening measures for safe tilting during emptying, which increases production costs and inflexibility.
Innovation Solution
A foldable large load carrier with a central discharge opening and a funnel-shaped insert element that aligns with the base part's outlet opening, allowing for easy emptying without the need for additional stiffening, and a sliding plate mechanism for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex stiffening measures are added to support side walls during tilting, then reliability of emptying process is improved, but device complexity and production cost increase
Solution Approach 1:
The patent extracts the stiffening function from the side walls and relocates it to the base part through recesses and support feet. This allows the side walls to remain simple and foldable while the base part provides the necessary structural support during tilting, thus improving reliability without increasing overall device complexity.
Solution Approach 2:
The patent transitions from a two-dimensional flat base part to a three-dimensional structured base part with recesses and support feet. This dimensional change allows the base part to provide structural support during tilting without adding complex stiffening elements to the side walls, resolving the contradiction between reliability and device complexity.
2Strength
If additional stiffening measures are implemented, then strength during tilting is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent segments the support function into separate components: the base part with recesses and support feet provides structural strength, while the side walls maintain their simple foldable design. This segmentation allows each component to be manufactured independently using standard processes, improving ease of manufacture while maintaining strength during tilting.
3Reliability
If side walls are made stiff and solid with additional measures, then reliability during tilting is improved, but adaptability deteriorates
Solution Approach 1:
The patent extracts the stiffening function from the side walls and places it in the base part. This allows the side walls to remain flexible and adaptable for different configurations (foldable, pluggable, or fixed), while the base part provides the necessary structural support during tilting, thus maintaining both reliability and adaptability.
4Ease of operation
If complex support plates are added to line tipping devices, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent designs the base part with integrated recesses and support feet that automatically engage with the tipping device during tilting. This self-service design eliminates the need for complex support plates lining the tipping device, as the carrier's own structure provides the necessary support, thus improving ease of operation without increasing device complexity.
