Solution Overview

Problem

Existing reverse vending machines (RVMs) inefficiently utilize space due to the need for objects to be manually fed and transported at a fixed height, limiting the effective use of storage bins and increasing operational costs.

Innovation Solution

A compact transport device integrated into the RVM that combines sorting and vertical transport, allowing objects to be lifted from a lower level to a higher level, enabling the use of taller storage bins without increasing the machine's footprint.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If objects are manually fed and transported at a fixed height of 900-1400mm, then ease of operation is improved, but space utilization deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidspace utilization
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The patent transitions from horizontal transport at fixed height to vertical transport, utilizing the height dimension to move objects from lower level positions to higher level positions. This dimensional change allows storage bins to be positioned at different heights, dramatically improving space utilization while maintaining operational efficiency through automated conveyor systems.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If storage bins are positioned below or at lower level than the conveyor, then ease of operation is improved, but volume of storage bins deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidvolume of storage bins
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The patent implements a dynamic conveyor system that can vertically transport objects to different height levels, allowing storage bins to be positioned at optimized heights rather than fixed below the conveyor. This dynamic positioning capability enables storage bins to utilize vertical space effectively, increasing their volume capacity while maintaining ease of operation through automation.

Inventive Principle:
Principle #15Dynamics

3Productivity

If a larger number of returned objects are stored in tall containers, then productivity is improved, but device complexity increases

Engineering Contradiction:
ImproveproductivityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines sorting and vertical transport functions into a single integrated device. The conveyor system simultaneously performs object sorting and vertical transportation to different storage levels, eliminating the need for separate sorting and lifting mechanisms. This merging of functions increases productivity by enabling tall storage bins while controlling device complexity through functional integration.

Inventive Principle:
Principle #5Merging (Combining)
