Adjustable Cam Modules for Archery Bow Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Archery bows require customization to fit individual archers' unique draw lengths and maximum draw weights, but existing methods for adjusting draw weight and length are limited, time-consuming, and require specialized equipment and skill.
Innovation Solution
The development of reversible and adjustable modules that can be attached to the cams of archery bows, allowing for translational movement and flipping to change the cable-engaging groove's peripheral profile, enabling independent adjustment of draw length and weight by altering the cam's rotational position and limb force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manufacturers produce a variety of bows with different draw weights and lengths, then archers can find a bow that fits their needs, but inventory complexity and manufacturing costs increase
Solution Approach 1:
The patent applies universality by designing a single bow model that can serve multiple customization needs through interchangeable modules. The modules attach to the cam system and provide different draw weights and lengths, allowing one bow to replace what would traditionally require multiple different bow models in inventory
Solution Approach 2:
The patent applies segmentation by dividing the customization function into separate modular components that can be attached or removed from the cam system. Each module represents a discrete unit of adjustment that can be independently selected and installed, rather than requiring a completely different bow for each configuration
2Adaptability or versatility
If dealers modify draw weight and length using dedicated equipment, then bows can be customized to fit archers, but the process becomes time-consuming and requires specialized skill
Solution Approach 1:
The patent applies dynamics by making the bow system adjustable and reconfigurable rather than fixed. The modules can be easily attached and detached from the cam system, allowing dynamic adjustment of draw weight and length without permanent modification or specialized equipment
Solution Approach 2:
The patent applies self-service by designing a system that archers can adjust themselves without requiring dealer intervention or specialized tools. The module attachment mechanism is designed to be user-friendly and tool-free, enabling archers to perform their own customization
3Manufacturing precision
If dedicated equipment is used to modify bows, then precise adjustments can be made, but the equipment requirement increases complexity and cost
Solution Approach 1:
The patent applies the intermediary principle by using standardized modules as mediators between the archer's needs and the bow system. These modules serve as pre-engineered intermediaries that provide precise adjustments without requiring complex modification equipment, as the precision is built into the module design itself

AI summary
An archery bow having a riser, a pair of flexible limbs extending from the riser, with each limb having a rotating member on an axel secured to the end thereof. At least one of the rotating members is a cam having a module secured thereto. The module is positionable with respect to the cam by translational movement and is also positionable on the cam with an opposite face against the cam to selectively provide a desired draw length.
