Modular Shooting Rest with Interchangeable Support Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shooting supports for firearms lack interchangeability in size and shape, leading to sagging or drooping when lifted, as they are typically designed as single, non-adjustable units that require replacement for different configurations.
Innovation Solution
A detachable support frame attachable to the firearm forearm, featuring spaced-apart attachment locations for multiple, interchangeably sized and shaped conformable rest units, utilizing hook-and-loop fasteners or other detachable mechanisms to secure the units without needing to remove the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single non-adjustable support unit is used, then the device structure is simple, but the adaptability to different shooting positions and conditions is poor
Solution Approach 1:
The support system is divided into a reusable frame component and interchangeable support units. The frame remains attached to the firearm while different support units can be swapped depending on the shooting position and conditions, allowing adaptability without redesigning the entire device.
Solution Approach 2:
The frame is designed as a universal base that can accommodate multiple types of support units with different sizes, shapes, and materials. This multi-functional design allows a single frame to serve various shooting scenarios by simply changing the support unit.
2Adaptability or versatility
If multiple support units of different sizes and shapes are provided, then the adaptability improves, but the device complexity increases
Solution Approach 1:
By separating the frame from the support units, the system allows multiple units to be used with a single frame. This segmentation reduces the overall complexity compared to having multiple complete support systems, as the frame and mounting mechanism remain constant.
Solution Approach 2:
The frame combines multiple attachment locations and a standardized mounting interface that works with all support units. This merging of functions into a single component reduces the need for multiple different frame designs, thereby reducing overall device complexity.
3Stability of the object's composition
If a long or large bag is attached to the forearm at one point, then the support coverage is adequate, but the bag sags or droops when lifted
Solution Approach 1:
The support unit is divided into a rigid frame portion that provides structural support and a conformable bag portion that provides comfort. The frame's multiple attachment points distribute the load and prevent sagging, while the bag maintains its size for adequate support coverage.
Solution Approach 2:
The rigid frame acts as an intermediary between the firearm and the conformable bag. It transfers and distributes the mechanical loads, preventing the bag from sagging when lifted, while allowing the bag to maintain its full size for support coverage.
4Adaptability or versatility
If the entire support device is exchanged for different configurations, then the adaptability is achieved, but the time and effort required increases
Solution Approach 1:
By making only the support units detachable and interchangeable while keeping the frame attached, the system reduces the time and effort required for configuration changes. Users only need to swap the support units rather than removing and reattaching the entire support device.
Solution Approach 2:
The frame is pre-attached to the firearm with multiple attachment locations prepared in advance. This preliminary setup allows support units to be quickly swapped without requiring complex alignment or reattachment procedures, reducing the time for configuration changes.

AI summary
Provided is a detachable supported shooting rest having a rigid support frame and a plurality of differently sized/shaped conformable support units. The frame is removably attached to a firearm and has spaced-apart support unit attachment locations. The conformable support units are interchangeably attachable to the frame at the attachment locations without removal of the frame from the firearm.
