Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Households face challenges in efficiently separating and compacting recyclable waste, particularly metal food and drinks containers, due to their large volume-to-weight ratio, which requires effective crushing and storage solutions to optimize recycling efficiency.
Innovation Solution
A can crushing and storing module with a chassis, a sliding crushing unit, and a storage unit, featuring a movable wall in the crushing compartment that reduces the size of the compartment to crush cans efficiently, and a linear ram or scissor jack-type mechanism for manual or non-manual operation, ensuring compact storage and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a separate crushing device is used outside the drawer, then the crushing function is achieved, but the structure becomes complex and the risk of jams increases
Solution Approach 1:
The crushing device is integrated directly into the drawer assembly, combining the storage function of the drawer with the crushing function in a single unit. This eliminates the need for separate crushing devices and reduces structural complexity while improving reliability by eliminating transfer points where jams could occur.
Solution Approach 2:
The drawer serves multiple functions: it acts as both a storage container for cans and the crushing mechanism itself. The drawer's structural components are designed to withstand crushing forces while maintaining its storage function, creating a multi-functional element that reduces overall system complexity.
2Device complexity
If a weak feeder drawer is used to access a separate crushing device, then the drawer structure is simple, but the risk of jams increases and crushing effectiveness is reduced
Solution Approach 1:
The feeder drawer and crushing device are merged into a single integrated unit. The drawer is designed to directly contain and crush cans within its own structure, eliminating the need to transfer cans to a separate crushing device and thereby eliminating the risk of jams at transfer points.
Solution Approach 2:
The drawer incorporates a movable wall that can dynamically change the crushing compartment size during operation. This dynamic adjustment allows the drawer to adapt to different can sizes and crushing stages, improving crushing effectiveness while maintaining structural simplicity.
3Productivity
If the crushing compartment size is reduced during operation, then cans are crushed effectively, but the drawer must withstand high crushing forces
Solution Approach 1:
The crushing compartment features a movable wall that dynamically reduces the compartment size during crushing operation. This dynamic compression allows effective crushing of cans while the drawer structure is designed to withstand the resulting high forces through appropriate material selection and structural reinforcement.
Solution Approach 2:
The drawer is constructed using composite materials or reinforced structures that provide the necessary strength to withstand crushing forces while maintaining a relatively simple overall design. The use of materials with high strength-to-weight ratios allows the drawer to handle crushing loads without excessive structural complexity.
4Volume of moving object
If cans are crushed with high compaction ratio, then storage efficiency is improved, but the crushing forces required increase
Solution Approach 1:
The movable wall enables dynamic compression that progressively reduces the crushing compartment size, achieving high compaction ratios (4:1 to 6:1) through controlled incremental compression. This dynamic approach allows effective volume reduction while the drawer structure is designed to handle the resulting forces.
Solution Approach 2:
The crushing mechanism utilizes multi-directional compression forces applied through the movable wall and drawer structure. By applying forces from multiple directions rather than single-point compression, the system achieves high compaction ratios while distributing the required forces across the robust drawer structure.
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 module effectively crushes cans by reducing their volume by a compaction ratio of 4:1 to 6:1, allowing for efficient storage and reducing the risk of jams and costs, while maintaining a robust structure for handling forces during crushing.
Implementation Method 1
A can is crushed by placing it in the crushing compartment and moving the movable wall to reduce the size of the crushing compartment, thereby subjecting the can to a crushing operation
Implementation Method 2
The module effectively crushes cans by reducing their volume by a compaction ratio of 4:1 to 6:1
