Modular Crossbow Stock with Toolless Quiver for Stability and Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectile launchers, such as crossbows, face a trade-off between accuracy and maneuverability due to their overall size, with longer weapons being cumbersome to handle but necessary for stability during firing.
Innovation Solution
A modular stock system with a toolless interface that allows for easy attachment and detachment to a crossbow, featuring a removable quiver and arming tool storage, enhancing stability and maneuverability by allowing the stock to be attached only when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the weapon is made longer to improve stability and accuracy, then accuracy is improved, but maneuverability deteriorates
Solution Approach 1:
The stock is divided into a main body portion and a separate projectile-carrying portion (quiver). The quiver can be detached from the main body, allowing the user to carry only the essential stock during maneuvering and attach the quiver when needed for firing. This segmentation resolves the contradiction by separating the functions of stability (main body) and projectile storage (detachable quiver).
Solution Approach 2:
The stock incorporates a toolless interface that allows dynamic attachment and detachment of the quiver to the main body. This dynamic configuration enables the user to adapt the weapon system to different operational needs - compact for movement, extended for firing - thereby resolving the static contradiction between length for accuracy and compactness for maneuverability.
2Measurement precision
If a stock is attached to improve stability, then accuracy is improved, but device complexity increases
Solution Approach 1:
The projectile-carrying function is extracted from the main stock body and placed in a separate detachable quiver. This extraction simplifies the main body structure while maintaining the ability to provide stability when the quiver is attached. The complexity is reduced by separating essential functions into independent components.
Solution Approach 2:
The toolless interface is designed to perform multiple functions: it provides structural support for accuracy, enables tool-free attachment/detachment for ease of operation, and allows configuration adaptation. This multi-functionality reduces the need for separate mechanisms, thereby managing complexity while achieving multiple objectives.
3Ease of operation
If the stock is made removable for ease of handling, then maneuverability is improved, but attachment complexity increases
Solution Approach 1:
The toolless interface is designed to be self-servicing, allowing the user to attach and detach the quiver without external tools or complex procedures. The interface structure itself provides the attachment and detachment mechanism through simple manual manipulation, thereby improving ease of operation without adding significant complexity.

AI summary
A removable stock for a crossbow includes a body. The body includes a front end and a mounting feature. The front end includes a stock interface that is configured to removably couple the stock to a rear interface of a crossbow. The mounting feature is configured to couple a projectile to the body of the removable stock.
