Multifunctional Pack Frame for Backrest and Firearm Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing external frame backpacks lack a comfortable backrest option in wilderness environments and fail to provide adequate support for firearms during hunting, leading to user fatigue and discomfort.
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 to stabilize the firearm during aiming.
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 frames can be configured to create a backrest, while notches in the frames provide firearm support, eliminating the need for separate equipment for these functions.
Solution Approach 2:
The frame is divided into separate vertical and horizontal components that can be independently positioned and configured. This segmentation allows the same structural elements to serve different functions (backrest vs. firearm support) by changing their relative positions and orientations.
2Adaptability or versatility
If the vertical frame and horizontal frame are fixed at a fixed angle, then the structure is stable, but it cannot adapt to different user preferences and conditions
Solution Approach 1:
The connection between the vertical and horizontal frames is made adjustable rather than fixed, allowing users to change the angle based on their needs. The quick-adjustment mechanism enables dynamic reconfiguration of the frame geometry to suit different users or conditions.
Solution Approach 2:
The angle parameter between the vertical and horizontal frames can be changed to optimize comfort and functionality. Users can adjust this geometric parameter to achieve the desired backrest angle or firearm support configuration.
3Stability of the object's composition
If the vertical frame is used as a backrest without support, then it is simple, but it lacks stability and compression support
Solution Approach 1:
The side supports are integrated into the existing pack frame structure, connecting to both the vertical and horizontal frames. This merging of the support function into the existing structure provides stability without requiring a completely separate support system.
4Ease of operation
If the pack frame is used for extended periods without firearm support, then it is simple, but it causes user fatigue
Solution Approach 1:
Firearm support notches are provided at specific locations on the vertical and horizontal frames where needed. This localized provision of support functionality adds minimal complexity only where required, rather than requiring a comprehensive firearm support system throughout the entire structure.
