Crossbow Bow Unit Replacement via Pivoting Magazine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crossbows require the magazine to be disconnected and emptied before replacing the bow unit, making the process inconvenient for users.
Innovation Solution
A crossbow design where the magazine remains pivotably attached to the crossbow, allowing the bow unit to be replaced by simply removing the pin from the clamping portion and protrusion, enabling the second end of the magazine to pivot away without removing the magazine from the body.

Engineering Contradiction Analysis
1Ease of operation
If the magazine is disconnected from the crossbow to replace the bow unit, then the bow unit can be replaced, but the magazine must be emptied and the disconnection process is inconvenient
Solution Approach 1:
The connection part is divided into two independent connection interfaces: one for the magazine (first connection part) and one for the bow unit (second connection part). This segmentation allows the magazine to remain connected while enabling independent replacement of the bow unit, eliminating the need to disconnect and empty the magazine during bow unit replacement.
Solution Approach 2:
The pin acts as an intermediary component that enables the magazine to be pivotally connected to the body while allowing the bow unit to be independently replaced. The pin can be removed to detach the bow unit without affecting the magazine connection, serving as a mediator between the two connection systems.
2Ease of operation
If the magazine is remain pivotably attached to the crossbow, then the magazine stays connected during bow replacement, but a pin mechanism is required to enable independent bow unit replacement
Solution Approach 1:
The connection part is segmented into distinct first and second connection parts with separate functions. The first connection part handles magazine attachment while the second connection part handles bow unit attachment. This segmentation allows independent operation of each connection system, enabling the magazine to remain connected while the bow unit can be replaced without complex interaction between the two connection systems.
Solution Approach 2:
The magazine is connected through a pivotal connection mechanism that allows it to be attached and detached when needed. The pin can be inserted to secure the magazine in place or removed to allow detachment. This dynamic connection mechanism provides the flexibility needed to keep the magazine connected during bow unit replacement while maintaining simplicity.

AI summary
A crossbow includes a body includes a connection part that includes a clamping portion. The clamping portion includes two side plates, and a space is formed between the two side plates. A bow unit includes a bow and a block which is formed to the middle portion of the bow. The block includes a protrusion which is accommodated in the space and clamped between the two side plates so as to connect the bow unit to the connection part. A magazine includes the first end thereof pivotably connected to the body, and the second end of the magazine is connected to the clamping portion. The magazine includes two lugs between which the clamping portion is located. A pin extends through the two lugs, the two side plates and the block to connect the magazine to the body. By removing the pin and pivoting the magazine, the bow unit is replaced.
