Arrow Rest Assembly with Biasing Spring for Precision Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery bow accessory mounting systems face challenges in precision adjustment due to large gaps between positions, difficulty in starting and stopping adjustments at discrete markings, and 'slop' or lag in the adjustment process, leading to inaccuracies and the risk of accessories being moved out of desired positions by vibrations or forces.
Innovation Solution
The bow accessory mounting system incorporates a vertical and lateral adjuster mechanism with a biaser that maintains constant thread-to-thread contact, eliminating 'slop' and allowing for immediate movement with each rotation of the adjustment knob, and a locking system to secure positions, enhancing precision and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adjustable mount is used to allow position adjustment of the arrow rest, then the adaptability is improved, but the measurement precision deteriorates due to large gaps between positions and slop in the adjustment mechanism
Solution Approach 1:
The patent employs a dynamic adjustment mechanism where the arrow rest can be continuously repositioned along the limb using a threaded rod and nut assembly, allowing smooth movement without discrete gaps between positions. The biasing spring maintains constant contact between threads to eliminate slop while preserving adjustability.
Solution Approach 2:
The invention changes the physical state of the adjustment mechanism by introducing a biasing spring that applies continuous force to maintain thread-to-thread contact. This parameter change (from static to dynamically biased connection) eliminates gaps and slop, achieving both adaptability and measurement precision.
2Ease of operation
If a typical adjustment knob is used, then the ease of operation is improved, but the measurement precision deteriorates due to slop or lag that prevents immediate movement and makes precision adjustments difficult
Solution Approach 1:
The biasing spring performs preliminary action by pre-loading the threaded connection to maintain constant contact between threads. This preliminary biasing force ensures that any rotation of the adjustment knob immediately translates to movement of the arrow rest without lag or slop, achieving both ease of operation and precision control.
Solution Approach 2:
The spring provides beforehand cushioning by maintaining continuous compressive force on the threaded components. This pre-applied force cushions against gaps and prevents play in the mechanism, ensuring that adjustment movements are immediately transmitted without precision loss.
3Ease of manufacture
If conventional attachment methods (screws or adhesives) are used, then the ease of manufacture is improved, but the adaptability deteriorates because it is difficult to adjust the position of the arrow rest after installation
Solution Approach 1:
The patent transforms the static attachment (screw or adhesive) into a dynamic adjustable system using a threaded rod, nut, and biasing spring assembly. This dynamic mechanism allows continuous position adjustment along the limb while maintaining secure attachment, achieving both ease of manufacture and adaptability.
Solution Approach 2:
The mounting system serves multiple functions: it provides secure attachment like conventional methods while simultaneously enabling continuous position adjustment. The threaded connection with biasing spring universalizes the attachment to be both fixed and adjustable, combining simplicity with adaptability.
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
This solution provides precise and repeatable adjustments, reducing the risk of accessories being inadvertently moved and improving user control over fine-tuning, ensuring accurate positioning of archery accessories on the bow.
Implementation Method 1
a biaser configured to generate a biasing force to maintain constant or continuous, thread-to-thread contact
Implementation Method 2
The adjustable component includes a threaded shaft configured to rotatably engage the support structure. Rotation of the threaded shaft produces movement of the adjustable component along a adjustment axis perpendicular to the adjustment markings.
