Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional load carriage devices are rigid, prone to breakage, inhibit movement, add weight, and are uncomfortable, making it difficult for individuals to carry heavy loads over long distances without straining their back and joints.
Innovation Solution
A load carriage frame with an aluminum frame top and base connected by a flexible spine and carbon fiber tubes, designed to distribute weight across the back, hips, and waist, accommodating ergonomic movement and providing a strong, lightweight structure that absorbs energy to prevent breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional rigid load carriage devices are used, then structural strength is improved, but the device becomes prone to breakage and uncomfortable during use
Solution Approach 1:
The patent applies the dynamics principle by replacing rigid frame structures with flexible materials. The load carriage device uses flexible spine and side tubes made of materials like elastic polymers or rubber, allowing the structure to dynamically adapt to body movements and absorb impact forces, thereby preventing breakage while maintaining strength.
Solution Approach 2:
The patent changes the physical parameters of the frame material from rigid to flexible. By using materials with appropriate elasticity and shock-absorbing properties, the frame maintains structural integrity while accommodating dynamic loads and reducing the risk of breakage during use.
2Force
If conventional rigid load carriage devices are used, then weight distribution is improved, but movement of the individual is inhibited
Solution Approach 1:
The flexible frame structure dynamically conforms to body movements, allowing free range of motion while maintaining effective weight distribution. The elasticity of the materials enables the frame to flex with the wearer's movements rather than restricting them.
Solution Approach 2:
The patent uses flexible structural elements instead of rigid shells. The flexible spine and side tubes act as compliant structures that distribute weight effectively while allowing the wearer to move freely, solving the contradiction between weight distribution and movement freedom.
3Force
If conventional load carriage devices are used, then load carrying capacity is improved, but the device adds substantially to the weight of the load
Solution Approach 1:
The patent employs composite materials that provide high strength-to-weight ratios. The flexible frame uses advanced polymers or rubber compounds that offer sufficient load-bearing capacity while minimizing the weight of the device itself, thus not adding substantially to the total load.
4Stability of the object's composition
If conventional rigid load carriage devices are used, then structural stability is improved, but comfort during use is reduced
Solution Approach 1:
The flexible frame provides dynamic stability by adapting to body movements and contours. Rather than relying on rigid fixed geometry, the elastic materials maintain structural stability through their ability to flex and return to original shape, significantly improving comfort during use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The frame effectively distributes the weight of heavy loads, enhancing mobility and comfort by using lightweight, durable materials that absorb shock, reducing the strain on the individual's body and preventing breakage.
Implementation Method 1
A spine is made of a flexible material configured to reverberate energy and connects a center portion of the proximal bar of the frame top to the rear portion of the frame base

AI summary
Implementations described and claimed herein provide systems and methods for load carriage using a load carriage apparatus. In one implementation, a frame top (102) is disposed at a proximal end of a load carriage frame (100). The frame top (102) includes a proximal bar (112) and a distal bar (114) each extending between a first side bar (116) and a second side bar (118). A frame base (104) is disposed at a distal end of the load carriage frame (100), and the frame base (104) includes a rear portion (124) connected to a first side portion (128) and a second side portion (130). A spine (106) connects a center portion of the proximal ba r(112) of the frame top (102) to the rear portion (124) of the frame base (104). A first tube (108) extends from the first side bar (116) to the frame base (104) relative to the first side portion (128). A second tube (110) extends from the second side bar (118) to the frame base (104) relative to the second side portion (130).
