Adjustable Archery Bow Grip for Torque Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Archery bows face issues with inconsistent arrow flight due to bow torque caused by the way the archer grips the bow, which can lead to rotational forces and misalignment of components, making it difficult to achieve accurate and consistent shots.
Innovation Solution
An adjustable riser assembly with a plate that can be attached to the handle portion of the bow at various laterally spaced positions, allowing for incremental adjustments of the grip's position relative to the center plane, and a grip that can be securely attached using a fastener system to counteract unwanted torques and forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the archer grips the bow in a conventional fixed position, then the bow structure is simple, but bow torque occurs causing inconsistent arrow flight
Solution Approach 1:
The grip system transitions from a fixed position to an adjustable position along the riser. The grip can be moved laterally to different locations to compensate for bow torque and achieve consistent arrow flight. This dynamic adjustment capability allows archers to optimize grip position based on their shooting style and bow characteristics.
Solution Approach 2:
The grip system is divided into separate functional components: the grip itself, the adjustment mechanism, and the mounting interface on the riser. This segmentation allows independent optimization of each component and enables flexible configuration to address specific torque issues without redesigning the entire bow system.
2Manufacturing precision
If the grip position is adjusted to counteract bow torque, then arrow flight consistency improves, but the adjustment mechanism increases device complexity
Solution Approach 1:
The system allows adjustment of the grip's positional parameters (lateral position along the riser) to optimize performance. By changing the position parameter, archers can fine-tune the grip location to counteract specific torque issues while maintaining a relatively simple adjustment mechanism.
Solution Approach 2:
The adjustment capability is applied locally at the grip-riser interface rather than requiring complex system-wide adjustments. The grip can be positioned at different locations along the riser to address local torque issues, while the rest of the bow system remains unchanged and simple.
3Adaptability or versatility
If integrated grips are used in the riser, then device complexity is reduced, but adaptability to different archer needs is limited
Solution Approach 1:
The riser is designed with a universal mounting interface that can accommodate different grip types and configurations. The adjustment mechanism provides multi-functionality by allowing the same basic system to be adapted to different archer needs, shooting styles, and torque conditions without requiring completely different designs.

AI summary
An adjustable grip system includes a plate having at least one grip adjustment aperture and a fastener, which is configured to extend through the grip adjustment aperture. The plate is attachable to the handle portion by the fastener at a plurality of laterally spaced apart positions. The plate or riser can have at least one riser mating protrusion insertable into at least one grip mating recess to retain the grip to the riser assembly. The grip can be laterally adjustable to control torques and forces applied to the bow by the hand of the archer when shooting a projectile.
