Solution Overview

Problem

Conventional bag loading devices struggle to efficiently load and transport full bags of debris, as they are difficult to lift and move without spilling due to weight and risk of tearing, especially for individuals with physical limitations.

Innovation Solution

A debris collection assembly that can be configured into a chute for loading debris and then reconfigured into a hauler with a skid member for safe and efficient transportation of loaded bags to a distant disposal point, using a planar member made of corrugated plastic or cardboard that forms a funnel-like guide and provides a hand grip for easy handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a loaded bag is dragged across the ground, then transportation to disposal location is enabled, but the bag risks ripping or tearing causing debris to spill

Engineering Contradiction:

Improvetransportation of loaded bagVSAvoidintegrity of loaded bag

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A rigid U-shaped support structure acts as an intermediary between the bag and the ground surface. This support structure distributes the contact force across a larger area and provides a more stable dragging surface, reducing the risk of bag rupture while enabling transportation to disposal locations

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a loaded bag is lifted for transport, then movement to distant location is enabled, but the heavy weight makes it difficult for users with physical limitations

Engineering Contradiction:

Improvemovement of loaded bagVSAvoidweight of loaded bag

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The rigid U-shaped support structure provides structural counterbalance that distributes the weight of the loaded bag across a broader base. This reduces the effective weight burden on the user during transport, making it manageable for individuals with physical limitations

Inventive Principle:

Principle #8Anti-weight (Counterweight)

3Ease of operation

If conventional bag holding devices are used, then the bag can be held in upright open position for loading, but the device cannot facilitate transportation of the loaded bag

Engineering Contradiction:

Improveloading of debris into bagVSAvoidtransportation capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The rigid U-shaped support structure serves multiple functions: it holds the bag in an upright open position during loading, provides structural support during transport, and enables both dragging and lifting modes of transportation. This multi-functionality eliminates the need for separate loading and transport devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A debris collection assembly can be alternatively configured to form: (i) a chute or bag holder and/or (ii) a bag hauler that can be utilized with conventional bags. The debris collection assembly can be formed from at least one planar member that can be selectively folded or otherwise configured to form a chute apparatus that can serve as a guide for directing loose debris into a bag. The planar member of the debris collection assembly can be removed from the bag and selectively reconfigured to form a hauler for selectively transporting a bag and its contents of desired distances.
