Adjustable Cable Guard for Archery Bows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller cable guards for archery bows are not easily adjustable, leading to inadequate clearance with arrows of varying fletching dimensions, causing potential contact issues, incorrect tracking, and side torque, which can result in injury or damage.
Innovation Solution
An adjustable cable guard system featuring a guard holder with a bifurcating slit that allows the cable guard to be adjusted along a lateral axis, using a sliding tongue within a clamping groove, enabling quick positioning and locking of the cable guard to maintain optimal clearance from the drawstring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional roller cable guards are installed to clear the fletching on standard size arrows, then the cables are maintained at a fixed position, but the cable guard cannot accommodate arrows with different fletching dimensions, causing insufficient clearance or excessive clearance
Solution Approach 1:
The cable guard system transitions from a fixed position to an adjustable position through the slit mechanism. The guard holder can be compressed to release the tongue from the clamping groove, allowing the cable guard to be repositioned along the holder to accommodate different fletching dimensions, then locked in place when compression is released.
Solution Approach 2:
The position parameter of the cable guard is made changeable through the compression mechanism. By applying compressive force to the slit, the width of the clamping groove changes, enabling the tongue to be released and repositioned. When compression is removed, the groove returns to its original width, locking the tongue in place.
2Ease of manufacture
If the cable guard position is fixed for standard arrows, then installation is simple, but re-adjustment for different arrow types is cumbersome and time consuming
Solution Approach 1:
The static cable guard installation is transformed into a dynamic, easily adjustable system. The compression-release mechanism allows the user to quickly reposition the cable guard by simply compressing the slit, moving the guard to the appropriate position, and releasing the compression to lock it in place, eliminating time-consuming re-installation procedures.
3Reliability
If the cable guard is positioned to clear smaller fletching, then clearance is adequate, but cables track incorrectly on wheels and create side torque on the wheels
Solution Approach 1:
The cable guard position becomes dynamically adjustable to achieve the optimal balance between arrow clearance and proper cable tracking. Users can compress the slit, reposition the guard holder along the rod to the precise position needed for each arrow type, and release the compression to lock the position, ensuring both adequate clearance and correct cable alignment without side torque.

AI summary
An adjustable cable guard for archery bows includes a guard holder and a cable guard held by the guard holder to engage a cable of the bow to maintain the cable a predetermined distance from a drawstring of the bow. The guard holder includes a body having a clamping groove having a length axis and a bifurcating slit that extends from the clamping groove into the body of the holder, and the cable includes a tongue located to be matingly and slidingly received by the clamping groove. The position of the tongue within the clamping groove may be locked against movement by compressing the slit to bear surfaces of the clamping groove against surfaces of the tongue.
