Solution Overview

Problem

Existing mobile compressed air device units require a carrying strap for the operator, limiting the handling radius and preventing multiple operators from using the device without transferring the entire compressed air storage unit, making it impractical for multi-operator handling.

Innovation Solution

Designing the compressed air connection as a carrier device for a hose-free connection between the working device and the storage unit, allowing the device to be handled as a single unit and easily transferred between operators, with a compact configuration enabling flexible positioning and rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a carrying strap is used to attach the compressed air storage unit to the operator, then the device can be carried on the body, but the handling radius is limited and multiple operator handover becomes complex

Engineering Contradiction:
Improvehandling easeVSAvoidhandover complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system is divided into two independent parts: the compressed air storage unit and the working device with carrier device. The carrier device includes a connection element that can be detached from the storage unit, allowing the working device to be separated and handed over independently without transferring the entire storage unit.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The carrier device acts as an intermediary between the compressed air storage unit and the working device. It provides a standardized connection interface that enables easy coupling and decoupling, facilitating smooth handover between operators while maintaining the integrity of the overall system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a hose connection is used between the storage unit and working device, then the device can be connected, but the handling radius is limited by hose length

Engineering Contradiction:
Improveconnection reliabilityVSAvoidhandling radius
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The hose connection is extracted and replaced by a direct mechanical connection through the carrier device. The connection element in the carrier device interfaces directly with the compressed air storage unit, eliminating the need for flexible hoses and enabling unlimited handling radius while maintaining reliable connection.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If the compressed air storage unit is carried on the operator, then independent operation is enabled, but the device cannot be easily handed over between operators

Engineering Contradiction:
Improveindependent operation capabilityVSAvoidhandover ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system is segmented into the compressed air storage unit and the working device with carrier device. The carrier device includes a detachable connection element that allows the working device to be separated from the storage unit, enabling independent operation while facilitating easy handover between operators.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection between the carrier device and compressed air storage unit is designed to be dynamic and reversible. The connection element can be quickly coupled and decoupled, allowing the system to transition between connected and separated states, which is essential for both independent operation and easy handover.

Inventive Principle:
Principle #15Dynamics
