Crossbow String Drawing Assist System with Wire Separator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crossbow string drawing assistance devices are limited by a one-piece structure that restricts mounting flexibility, requires significant arm strength, and is difficult to install and manufacture, leading to user inconvenience and inefficiency.
Innovation Solution
A crossbow string drawing assistance system with a wire separator assembly and bowstring drawing assistance device mounted separately, utilizing a pull hook and reeling assembly to form a nearly straight pull wire, allowing the bowstring to be drawn and engaged with an engaging member, enabling flexible mounting and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a one-piece structure is used for the bowstring drawing assistance device, then the structure is simple, but the mounting flexibility is limited and the device is difficult to install and manufacture
Solution Approach 1:
The bowstring drawing assistance device is divided into separate components: a wire separator assembly and a bowstring drawing assistance device proper. This segmentation allows each component to be optimized independently and enables flexible mounting configurations on the crossbow, resolving the contradiction between structural simplicity and mounting flexibility.
2Device complexity
If the wire separator device is integrated into the bowstring drawing assistance device, then the structure is compact, but the mounting position is restricted to specific angles only
Solution Approach 1:
By separating the wire separator assembly from the bowstring drawing assistance device, the invention enables independent positioning and angular adjustment of each component. The wire separator assembly can be mounted at optimal angles independent of the main device, eliminating mounting position restrictions while maintaining structural efficiency.
3Device complexity
If the pull wire is not properly separated from the bowstring, then the device structure is simple, but the pull wire may be stuck on the bowstring drawing assistance device
Solution Approach 1:
The wire separator assembly extracts and separates the pull wire from the bowstring at a dedicated location. This separation prevents the pull wire from becoming stuck on the bowstring drawing assistance device during operation, ensuring reliable wire retrieval while maintaining a relatively simple overall device structure.
4Ease of manufacture
If the bowstring drawing assistance device is mounted at fixed positions, then the manufacturing is easier, but the user cannot adjust the mounting position according to habit
Solution Approach 1:
The divided structure with separate wire separator assembly and bowstring drawing assistance device allows each component to be manufactured with standardized mounting interfaces. Users can then adjust the mounting positions of individual components according to their preferences and habits, achieving both manufacturing ease and operational flexibility.

AI summary
A crossbow string drawing assistance system includes a crossbow, a bowstring drawing assistance device and a wire separator assembly, the bowstring drawing assistance device and the wire separator assembly are mounted on different positions of the crossbow, a pull hook of the bowstring drawing assistance device can hook a bowstring of the crossbow, a pull wire is inserted through the two hooks to engage with the wire separator assembly; when the bowstring drawing assistance device continuously packs the pull wire, the pull wire on the wire separator assembly is engaged to force the bowstring to move toward the wire separator assembly until the bowstring is engaged with the engaging member, so as to complete a drawing operation. Therefore, a user can mount and dismount the bowstring drawing assistance device easily according to habit, so as to mount the bowstring drawing assistance device in a comfortable position.
