Archery Finger Tab With Adjustable Hinge Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional archery finger tabs do not accommodate individual archers' unique hand shapes and habits, leading to unstable hooking actions, bowstring vibration, and inconsistent arrow trajectories due to their fixed, right-angle support plates that do not adapt to varying finger lengths, thicknesses, and bending degrees.
Innovation Solution
An archery finger tab with a plate-shaped body featuring a forward-rearward guide rail, a rotatable mount with a hinge, and a little finger support with a second hinge, allowing adjustable vertical position, height, and inclination through screw-based fastening and elastic members for customizable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If support plates are manufactured at right angles (fixed structure), then manufacturing is simple and consistent, but archers must adapt their hands and hooking actions to the finger tabs instead of adapting the finger tabs to their hooking positions
Solution Approach 1:
The support plate is transformed from a fixed rigid structure to an adjustable dynamic structure. The support plate can be rotated about a first axis and the support angle can be adjusted and fixed at different angles, allowing the finger tab to adapt to different archer hand shapes and hooking positions while maintaining manufacturing simplicity through standardized adjustable components.
Solution Approach 2:
The support angle parameter of the support plate is made variable rather than fixed. By allowing rotation and adjustment of the support plate at different angles, the system can accommodate individual archer preferences for support angles while maintaining consistent manufacturing processes for the standardized adjustable components.
2Manufacturing precision
If the finger tab structure is fixed and standardized, then manufacturing consistency is high, but it cannot accommodate different finger lengths, thicknesses, and bending degrees of individual archers
Solution Approach 1:
The finger tab is divided into multiple independent adjustable segments: the support plate that can rotate about a first axis, the hinge part that can rotate about a second axis, and the fastening mechanism that allows fixing at different positions. This segmentation allows each component to be manufactured with high precision and consistency while the assembled system can accommodate individual finger variations through adjustment.
Solution Approach 2:
The previously fixed structure is replaced with dynamic adjustable components. The support plate can be rotated and fixed at different angles, the hinge part can rotate to adjust the position, and these adjustments allow the standardized components to adapt to different finger lengths, thicknesses, and bending degrees while maintaining manufacturing precision.
3Device complexity
If archers adapt their hands to fixed finger tabs, then the finger tab structure remains simple and consistent, but hooking action stability decreases leading to bowstring vibration and inconsistent arrow trajectories
Solution Approach 1:
The fixed structure is replaced with adjustable dynamic components including a rotatable support plate and a rotatable hinge part. This allows archers to adjust the finger tab to match their natural hand shape and hooking action, improving hooking stability and reducing bowstring vibration while maintaining relatively simple device structure through standardized adjustable mechanisms.
Solution Approach 2:
The support angle and position parameters are made adjustable rather than fixed. By allowing rotation of the support plate about a first axis and the hinge part about a second axis, archers can optimize the hooking action stability for their individual hand shapes, eliminating the need for complex structures while improving reliability.
