Archery Bow Grip Reducing Torque via Rotating Outer Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bow torque introduced by the human hand during archery reduces accuracy, as the bow grip/handle can cause unwanted torque, leading to inaccurate arrow propulsion, especially for longer distance shots.
Innovation Solution
An archery bow system with an outer bow grip that rotates relative to an inner bow handle only when the bow is drawn, minimizing torque by allowing a limited angular range of rotation during the draw and preventing rotation in the undrawn state, using a spring mechanism and pin/socket configuration for frictionless pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the bow grip/handle surface area is reduced to minimize torque, then bow torque is reduced, but the archer cannot obtain consistent hand placement
Solution Approach 1:
The bow grip is divided into two independent components: an inner handle and an outer grip. The inner handle provides a stable, non-rotating interface with the bow, while the outer grip allows rotational movement. This segmentation enables the archer to maintain consistent hand placement on the outer grip while the inner handle remains stationary relative to the bow, eliminating torque without sacrificing placement consistency.
Solution Approach 2:
The outer grip is designed to rotate dynamically relative to the inner handle during the drawing process. This rotational freedom allows the archer's hand to naturally settle into a consistent position on the outer grip while the inner handle remains fixed to the bow, thereby minimizing torque while maintaining hand placement consistency.
2Object-affected harmful factors
If a loose, relaxed hand grip is used to reduce torque, then bow torque is reduced, but control over the bow is diminished
Solution Approach 1:
The grip system separates the functions of torque reduction and control. The outer grip, which contacts the archer's hand, is designed to rotate freely to minimize torque. The inner handle, which is fixed to the bow, maintains structural integrity and control. This segmentation allows the archer to use a relaxed grip on the outer grip while the inner handle ensures proper bow control.
Solution Approach 2:
The inner handle acts as an intermediary between the bow and the archer's hand. It transmits the archer's control inputs to the bow while isolating the bow from rotational torque. The outer grip serves as a mediator that allows the archer's hand to rotate without transmitting that rotation to the bow, thereby maintaining control while reducing torque.
3Stability of the object's composition
If the outer bow grip is prevented from rotating in the undrawn state, then stability is maintained, but torque reduction during drawing is limited
Solution Approach 1:
The grip system transitions from a static, non-rotating configuration in the undrawn state to a dynamic, rotating configuration during drawing. In the undrawn state, the outer grip is constrained to maintain stability. During drawing, the constraint is released, allowing the outer grip to rotate relative to the inner handle, thereby reducing torque while maintaining initial stability.
Solution Approach 2:
The outer grip is pre-positioned and constrained in the undrawn state to ensure stability during setup and aiming. The rotational freedom is activated only when needed during the drawing motion, allowing the system to maintain stability when required and reduce torque when necessary.
4Object-affected harmful factors
If the outer bow grip is enabled to rotate during drawing, then torque is reduced, but structural complexity increases
Solution Approach 1:
The grip is segmented into two independent parts: a simple inner handle that attaches directly to the bow and an outer grip that provides rotational freedom. This segmentation achieves torque reduction through a relatively simple structure, avoiding the need for complex mechanisms while still enabling the necessary rotational movement.
Solution Approach 2:
The outer grip is designed with inherent rotational freedom through its connection to the inner handle, eliminating the need for complex locking or unlocking mechanisms. The dynamic rotation is achieved through the basic geometric relationship between the outer grip and inner handle, keeping the overall structure simple while enabling torque reduction.
