Detachable Load Carrier Structure for Lightweight Equipment Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrying systems for equipment, such as those used by firefighters, suffer from low carrying comfort and require heavy frame structures that complicate handling and distribution of load forces.
Innovation Solution
A carrying system with a load node featuring a reinforcing plate and a back plate, where the load node serves as the primary connection point, reducing weight and improving comfort by distributing load forces through a load carrier that is detachably attached to a carrying rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a frame structure is used to distribute load forces, then the structural strength is improved, but the weight increases and carrying comfort deteriorates
Solution Approach 1:
The frame structure is segmented into a modular carrying rack with separate components (back plate, shoulder straps, waist strap, load node) that can be independently configured. This allows the structure to provide necessary strength only where needed while reducing overall weight through selective placement of load-bearing elements.
Solution Approach 2:
The load node incorporates a reinforcing plate with localized reinforcement at the connection point for the load carrier. This provides high structural strength exactly where the load is applied, while the rest of the carrying rack remains lightweight without unnecessary reinforcement.
2Strength
If a frame structure is used to attach equipment, then the load distribution is improved, but the device complexity increases
Solution Approach 1:
The load distribution function is extracted from a complex frame structure and concentrated into a simplified load node with a reinforcing plate. This single component performs the load distribution function that would otherwise require an entire frame system, significantly reducing device complexity.
Solution Approach 2:
Multiple functions are merged into the load node: it serves as the attachment point for the load carrier, the connection point for shoulder and waist straps, and the structural element for load distribution. This consolidation eliminates the need for separate frame components.
3Strength
If equipment is attached directly to the frame, then the connection strength is improved, but the ease of operation deteriorates
Solution Approach 1:
The load carrier is made detachably attachable to the carrying rack, transforming the connection from fixed to dynamic. This allows the equipment to be easily attached and detached as needed, significantly improving ease of operation while maintaining connection strength through the reinforced load node.

AI summary
The present disclosure provides a carrying system for an item of equipment, comprising a carrying rack on which shoulder straps and a waist strap are arranged, and a load carrier to which the item of equipment is releasably attachable, wherein the load carrier is formed by an inherently rigid carrying element which supports the weight of the item of equipment in the vertical direction. Provision is made for that the load carrier is releasably attachable to the carrying rack, wherein the load carrier preferably comprises connection elements for releasable connection to connection elements arranged at a lower end of the carrying rack, so that the introduction of force from the load carrier into the carrying rack takes place at the lower end thereof.
