Solution Overview

Problem

Existing structural support members for breathing apparatus harnesses offer limited protection to components and have time-consuming assembly methods, which are not efficient for securing and safeguarding the equipment.

Innovation Solution

A structural support member comprising first and second parts that define a housing to protectively retain the gas-cylinder reducer valve, with a frame design that includes a lower portion for the cylinder, an upper portion, and side limbs creating a void to accommodate the user's back, allowing for easy assembly and component protection without additional fixing components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional fixing mechanisms (snap-fit, adhesive, screws, nuts and bolts) are used to mount components on the structural support member, then the components can be securely mounted, but the assembly method becomes time-consuming

Engineering Contradiction:
Improvecomponent mounting securityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The structural support member is divided into a first part and a second part that can be assembled separately around the reducer valve. This segmentation allows for easier, faster assembly while maintaining secure mounting of components through the defined housing structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The housing is designed to nest around the reducer valve, with the first and second parts forming an enclosed space that protects the valve. This nested structure eliminates the need for additional fixing components while ensuring secure retention.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If traditional open mounting methods are used for components on the structural support member, then assembly is simple, but the level of protection offered to the components is limited

Engineering Contradiction:
Improveassembly simplicityVSAvoidcomponent protection level
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The housing formed by the first and second parts creates a nested enclosure around the reducer valve and other components. This provides protective retention while maintaining assembly simplicity through the integrated design that requires no additional fixing mechanisms.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The housing structure acts as a protective shell that encloses the components. The design provides environmental protection while remaining simple to manufacture and assemble as an integrated unit.

Inventive Principle:
Principle #30Flexible shells and thin films
