Golf Club Sensor Wiring Substrate for Dynamic Strain Measurement

Solution Overview

Problem

Conventional methods for measuring physical values like strain and torsion in golf club shafts during swinging motions are hindered by uncertain variations due to wiring cables, which affect the behavior of the golf club shaft and introduce air resistance, leading to inaccurate assessments.

Innovation Solution

A sensor wiring substrate with a flexible board, couplers, and wires is used, which is helically wound around the golf club shaft, closely attached to its curved surface, reducing air resistance and preventing damage from warping, allowing for reliable measurement and transmission of physical values to an external device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If wiring cables are used to connect sensors to measuring devices, then sensors can be attached to golf club shafts, but the cables cause variable behavior due to their weight and air resistance, leading to measurement uncertainty

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidbehavior consistency

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent extracts and removes the harmful wiring cable from the system by using wireless communication technology. Sensors attached to the golf club shaft transmit measurement data wirelessly to external devices, eliminating the cable that caused variable behavior due to weight and air resistance during swinging motions.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical wiring cable system with an electromagnetic wireless communication system. Instead of using physical cables to transmit sensor data, the system uses wireless transmission technologies (such as radio frequency communication) to send measurement data from sensors on the moving golf club to external receiving devices.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If sensors are attached to golf club shafts during swinging motion, then dynamic measurement is possible, but the wiring cable obstructs natural swing motion and introduces air resistance

AI summary

A golf club measuring system is designed to dynamically measure physical values of a golf club shaft during its swinging motion. A sensor wiring substrate includes a flexible board (e.g. polyethylene terephthalate material), a connector, a plurality of couplers, and a plurality of wires. A plurality of sensors is connected to the sensor wiring substrate via a plurality of couplers. The sensor wiring substrate is helically wound about the golf club shaft such that the flexible board is slightly warped and closely attached to the curved surface of a golf club shaft, thus reducing air resistance occurring on the golf club shaft being swung. An external device (e.g. a strain measuring device) is connected to the connector of the sensor wiring substrate so as to receive signals representing physical values (e.g. strain values), occurring on the golf club shaft being swung, from a plurality of sensors.
