Archery Bow Bushing Structure for Stable Hidden Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery bow fasteners lack stability and visibility during installation, leading to misalignment and visible blemishes, which affect the shooting experience and overall satisfaction.
Innovation Solution
The introduction of a bushing design with a drive feature positioned deep within the bore and a threaded feature, featuring unique characteristics to enhance stability and minimize visible installation marks, along with an interference fit to secure the bushing to the riser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drive feature is positioned accessible within the bore, then ease of operation is improved, but visibility during installation deteriorates causing misalignment
Solution Approach 1:
The drive feature is positioned at the base of the bore rather than at the accessible end, utilizing the depth dimension of the bore to relocate the driving surface. This allows the drive feature to be hidden from direct view while remaining accessible through the bore aperture, resolving the contradiction between ease of operation and visibility during installation
2Reliability
If the bushing is secured with visible fasteners, then reliability of attachment is improved, but visible blemishes increase affecting appearance
Solution Approach 1:
The drive feature is extracted from the external surface and relocated to the base of the bore, allowing the fastening mechanism to be hidden within the bushing structure. This eliminates visible blemishes on the external surface while maintaining secure attachment through the internal drive feature and threaded engagement
3Stability of the object's composition
If the threaded feature is positioned deeper in the bore, then stability during installation is improved, but device complexity increases
Solution Approach 1:
The bore serves multiple functions: it provides the pathway for installing the bushing, contains the threaded feature for secure attachment, and houses the drive feature at its base for tool engagement. This multi-functionality achieves deep positioning of the threaded feature for stability without significantly increasing device complexity
