Motion Detection Device With Interchangeable Base And Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion analysis techniques for sporting equipment, such as golf clubs, require multiple sensors and jigs, leading to high costs and complex preparation processes, and cannot maintain alignment during impact, potentially damaging the equipment.
Innovation Solution
A motion detection device with a base and holder that use a recessed and protruding fitting mechanism, allowing easy attachment and removal without adhesives, and incorporating an inertial sensor with a direction indicator for accurate alignment, reducing preparation time and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a three-axis accelerometer is fixed to a golf club using adhesive, then the sensor can be installed on the golf club, but the adhesive may detach during impact and cause misalignment
Solution Approach 1:
The patent replaces the chemical bonding method (adhesive) with a mechanical fastening system consisting of a holder with clamping members that physically secure the base to the golf club shaft. This mechanical system provides reliable alignment stability during impact while maintaining ease of installation through tool-free adjustment.
Solution Approach 2:
The patent introduces a holder as an intermediary component between the base and the golf club shaft. This holder includes clamping members that can be adjusted to securely hold the base at a predetermined position on the shaft, providing both easy installation and reliable alignment stability during impact.
2Adaptability or versatility
If multiple jigs and three-axis accelerometers are prepared for individual golf clubs, then each golf club can be analyzed, but the cost and preparation processes increase
Solution Approach 1:
The patent designs the base and holder as universal components that can be attached to various types of golf clubs without requiring club-specific jigs or sensors. The holder can be positioned at different locations on the shaft, and the base can accommodate different sensor configurations, enabling a single set of components to serve multiple golf clubs.
Solution Approach 2:
The patent divides the motion detection device into separable components: a holder that attaches to the golf club shaft and a base that can be attached to or removed from the holder. This segmentation allows the base with sensors to be reused across multiple golf clubs by simply reattaching it to different holders or repositioning it on the same holder.
3Measurement precision
If the motion detection device is firmly fixed to maintain alignment during impact, then measurement accuracy is improved, but the attachment process becomes more complex
Solution Approach 1:
The patent employs a dynamic attachment system where the holder's clamping members can be easily adjusted during installation to achieve the desired position and orientation of the base on the golf club shaft. Once positioned, the clamping members provide firm securing to maintain alignment accuracy during impact, combining ease of operation with measurement precision.
