Solution Overview

Problem

Households face challenges in efficiently storing and compacting recyclable waste, particularly packaging, cartons, and containers, due to their large volume-to-weight ratio, which requires effective compaction and separation for recycling purposes.

Innovation Solution

A compacting and storing module with a slidable receptacle and compacting plate driven by a linear ram or scissor jack mechanism, allowing for efficient compaction and storage of recyclable waste within a domestic appliance, featuring a cage-like container part and load-bearing members for stability and support during the compaction process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If recyclable waste is stored without compaction, then storage capacity is reduced, but waste volume remains large requiring more space

Engineering Contradiction:
Improvewaste volumeVSAvoidstorage space required
Core Design Contradiction:
Volume of moving objectVSVolume of stationary object

Solution Approach 1:

The patent employs a dynamic compaction system where a movable compacting means is driven into the receptacle to compress waste materials. The drive means enables the compacting means to move between a compacting position (inside the receptacle) and a withdrawing position (outside the receptacle), dynamically reducing waste volume on demand rather than maintaining constant compression.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The compacting means is designed to be received within the receptacle during compaction operations, with the drive means positioned to drive the compacting means into the receptacle. The system nests the compacting mechanism within the storage structure, allowing the compacting means to be stored in or near the receptacle when not in use, maximizing space utilization.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Productivity

If a compacting mechanism is added to the storage system, then waste compaction capability is improved, but device complexity increases

Engineering Contradiction:
Improvecompaction capabilityVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The drive means serves multiple functions: it drives the compacting means into the receptacle for compaction, withdraws the compacting means after compaction, and can be integrated with the drawer assembly to provide both storage and compaction operations through a single actuating mechanism.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the storage function (receptacle) and compaction function (compacting means with drive means) into a single integrated assembly. The compacting means is positioned to work within the same space as the receptacle, and the drive means is integrated with the drawer structure, merging multiple functions into one cohesive system rather than separate units.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If the compacting means is driven into the receptacle for compaction, then compaction effectiveness is improved, but the compacting means may become stuck or jammed

Engineering Contradiction:
Improvecompaction effectivenessVSAvoidoperational reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system is designed with a predetermined withdrawal action where the drive means automatically reverses and withdraws the compacting means from the receptacle after compaction is complete. This preliminary withdrawal action prevents the compacting means from remaining in the compressed waste material where it could become stuck, ensuring reliable operation through automatic reset.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If the receptacle is made accessible for waste deposition, then ease of operation is improved, but structural support during compaction becomes more challenging

Engineering Contradiction:
Improvewaste deposition accessibilityVSAvoidstructural support strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The system is segmented into a movable drawer assembly containing the receptacle and a fixed or separately mounted compacting assembly. This segmentation allows the receptacle to be easily accessible and movable for waste deposition, while the compaction function is provided by a separate structurally supported compacting means that can be driven into the receptacle only when needed, distributing structural requirements across different components.

Inventive Principle:
Principle #1Segmentation
