Ceiling-Mounted Archery Paper Tuning Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current archery paper tuning devices fail to securely hold paper on all four sides, are not easily adjustable, and occupy floor or wall space, limiting their usability and effectiveness in providing comprehensive and user-friendly analysis of arrow flight characteristics.
Innovation Solution
A ceiling-mounted archery paper tuning device with a front and back frame system that holds paper taut on all four sides, featuring adjustable screws for tension and a unique design allowing easy paper feeding and exit, taking up no floor space and facilitating objective analysis of arrow flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the paper is held taut at only the top and bottom of the device, then the device structure is simpler, but the paper is not held taut in all four directions resulting in poor tuning accuracy
Solution Approach 1:
The device is divided into a front frame assembly and a back frame assembly, with each frame having independent corner blocks and adjustment screws. This segmentation allows each corner to independently secure the paper, ensuring the paper is held taut in all four directions while maintaining modular construction that doesn't overly complicate the overall structure.
2Adaptability or versatility
If the device is mounted on the floor or wall, then the device is stable, but it occupies floor or wall space limiting usability
Solution Approach 1:
The device transitions from traditional floor or wall mounting (2D space occupation) to ceiling suspension (utilizing the vertical dimension). By mounting the device from the ceiling using suspension cords attached to ceiling blocks, the device hangs in the air space without occupying valuable floor or wall area, enabling archers to tune bows in locations with limited floor space.
3Ease of operation
If the device is fixed and non-adjustable, then the device structure is simpler, but the device is not easily adjustable for different users
Solution Approach 1:
The device incorporates adjustable corner blocks with threaded adjustment screws at each corner of both the front and back frames. These dynamic adjustment mechanisms allow users to modify the position and tension of the paper holder, accommodating different user preferences and tuning requirements while maintaining overall structural integrity through a relatively simple screw-based adjustment system.

AI summary
An archery arrow trajectory evaluation device, that is suspended from above by a pair of cords. Holds a paper roll above a framed structure. The paper feeds down in between the front and back frame. Frames are held together with hollow screws and nuts in each corner. Each nut is adjustable allowing the user to tighten the front and back frame together to hold the paper taut on four sides, but still allowing the paper to pass through from the top of the frame down through to the bottom. Once the paper is held securely between the frames an arrow may be shot through the center of the frames to determine the trajectory of the arrow. If the bow is tuned the arrow will pass through the paper and the tear left behind will be symmetrical. The tear will indicate to the user what adjustments are needed.
