Problem
Existing external frame backpacks lack a comfortable backrest option in wilderness settings and fail to provide adequate support for firearms during hunting, leading to user fatigue and difficulty in maintaining a steady aiming position.
Innovation Solution
A multifunctional pack frame with a vertical and horizontal frame configuration that allows for adjustable angle support, incorporating side supports and a detachable cushion for comfort, and a firearm support structure that provides both vertical and lateral support for the firearm's forend, enabling comfortable seating and stable firearm positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional external frame backpack is used, then the pack can carry loads, but it lacks backrest support and firearm support functionality
Solution Approach 1:
The pack frame is designed to perform multiple functions: carrying loads, providing backrest support, and supporting firearms. The vertical and horizontal frame members are configured to create both a backrest surface and a firearm support structure with forend support members, allowing a single device to serve multiple purposes in wilderness and hunting scenarios.
Solution Approach 2:
The frame is divided into distinct functional segments: vertical frame members for backrest support, horizontal frame members for structural stability, and separate forend support members specifically configured to support firearm forends. This segmentation allows each component to be optimized for its specific function while maintaining overall integration.
2Reliability
If the user holds the firearm for prolonged periods, then the user can maintain a steady aiming position, but user fatigue increases
Solution Approach 1:
The pack frame's forend support members are configured to automatically support the firearm forend when placed upon them, providing stable aiming support without requiring active user intervention. The horizontal and vertical frame members work together to create a passive support structure that maintains firearm stability while reducing user fatigue.
3Stability of the object's composition
If the vertical frame and horizontal frame are connected at a fixed angle, then the backrest provides stable support, but the adaptability to different user preferences is limited
Solution Approach 1:
The connection between vertical and horizontal frame members is designed to allow angle adjustment, transforming the backrest from a static fixed-structure to a dynamic adjustable-structure. This enables users to modify the backrest angle according to their comfort preferences while maintaining stable support when positioned.
