Solution Overview
Problem
Existing methods and apparatuses fail to achieve high consistency and correct orientation of structural asymmetries in shafts such as archery arrows and golf club shafts, leading to deviations in performance.
Innovation Solution
An indexing and batching apparatus that applies longitudinal force to shafts, measuring their properties under load to identify and align structural asymmetries, allowing for consistent batching based on similar characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing methods and apparatuses are used to make shafts, then manufacturing is simpler and less complex, but the consistency and orientation of structural asymmetries in shafts are insufficient
Solution Approach 1:
The apparatus segments shafts into batches based on their structural characteristics by applying longitudinal force and observing deflection patterns. Each shaft is individually tested and grouped with similar shafts, creating homogeneous batches that improve consistency while using a systematic rather than overly complex approach.
Solution Approach 2:
The apparatus performs preliminary testing of shafts before final assembly or use by applying longitudinal force and measuring deflection. This preliminary action identifies structural asymmetries and allows for proper batching and orientation before the shafts are put into service, ensuring consistency without requiring complex post-manufacturing adjustments.
2Manufacturing precision
If existing methods are used for shaft production, then the process is faster and more efficient, but the orientation of structural asymmetries and performance consistency are compromised
Solution Approach 1:
The apparatus allows shafts to reveal their own structural characteristics through natural deflection under longitudinal force. By observing how each shaft bends and deflects, the system automatically identifies structural asymmetries and determines proper orientation without requiring complex external measurement equipment or manual inspection, maintaining efficiency while improving precision.
Solution Approach 2:
The apparatus changes the physical state of the shaft by applying longitudinal force, causing the shaft to deflect and reveal its structural characteristics. This parameter change (from static to loaded state) allows for identification of asymmetries and proper batching without adding significant time to the production process.
3Reliability
If shafts are used without indexing and batching, then the process is simpler and quicker, but performance deviations and inconsistencies occur due to structural asymmetries
Solution Approach 1:
The apparatus replaces complex measurement and inspection systems with a simple mechanical force application mechanism. By applying longitudinal force and observing natural deflection patterns, the system identifies structural asymmetries without requiring sophisticated sensors, electronics, or complex measurement equipment, thus improving reliability while keeping the device relatively simple.
