Archery Rest System With In-Line Dampening Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional archery rest systems, particularly limb actuated designs, face issues such as string stress, mechanical stress on mechanisms, and high wear due to lack of force absorption, leading to arrow flight imbalances and equipment failures. Additionally, archers need to purchase multiple rest styles for different applications, and existing systems do not allow for third axis alignment assessment at full draw.
Innovation Solution
An archery rest system that combines fall away, limb actuated, and fixed launcher configurations, featuring a rotatable shaft with a lever arm, in-line dampening spring, and adjustable attachment cord, allowing for multiple configurations and third axis alignment assessment, with a design that absorbs load and reduces mechanical stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If limb actuated rest design is used, then arrow fletching clearance problem is eliminated, but string stress and mechanical stress on mechanism increase causing string breakage and part wear
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a spring mechanism that absorbs the force imparted by the limb before it can cause damage. The spring is pre-positioned to cushion the impact when the launcher reaches the end of its travel, preventing string breakage and mechanical failure while maintaining the benefits of the limb actuated design
2Device complexity
If fixed launcher position rest is used, then design simplicity and reliability are improved, but ability to clear arrow fletchings is lost
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed launcher position to a movable launcher that can dynamically adjust its position. The launcher is designed to move downward upon release to clear the arrow fletchings, combining the simplicity of a fixed rest with the functionality of a dynamic clearing mechanism
3Adaptability or versatility
If archers purchase multiple rest styles for different applications, then versatility is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by designing a single archery rest system that can function in multiple modes. The rest can be configured to operate as a traditional fixed rest, a limb actuated rest, or a fall-away rest by adjusting the spring tension and launcher position, eliminating the need for archers to purchase multiple separate rest systems
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a versatile and reliable archery rest solution that reduces mechanical stress, maintains arrow alignment, and allows for third axis adjustment, enhancing accuracy and durability across various archery applications.
Implementation Method 1
Spring means biases the arrow shaft into an up launcher position
Implementation Method 2
an in-line dampening spring mounted between the lever arm and the securing means... with the dampening spring absorbing load imparted on the attachment cord when the rotating shaft reaches a rotation travel limit

AI summary
An archery rest system comprises a body mounted to the bow. A shaft is mounted within the body and a lever arm is secured to the shaft. An opening is formed in the body with an arrow launcher mounted to the shaft and extending through the opening. A spring biases the arrow launcher in an up position. A cord is secured to the lever arm. A securing mechanism secures the cord to the bow and an in-line dampening spring is mounted between the lever arm and the securing mechanism. With the bow at rest, the launcher moves to a down position out of contact with the arrow. Upon bow draw, the launcher moves into the up position contacting the arrow. Upon bow firing, the launcher moves to the down position with the spring absorbing load imparted on the cord when the shaft reaches a rotation travel limit.
