Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional putting exercisers primarily measure the speed and direction of a golf ball, lacking the ability to provide objective information on the tempo and speed of the putter, making it difficult for users to improve their putting technique effectively.
Innovation Solution
A putting exerciser equipped with sensor installation units, radiation and light receiving units, a speed detection unit, position measurement unit, operation control unit, and storage unit, which measures the tempo and speed of the putter by detecting the light reflection and position changes of the golf ball, and calculates the tempo and speed of the putter to provide users with accurate data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional putting exercisers measure only the speed and direction of a golf ball, then the device complexity is low, but the measurement precision and information quality are insufficient for effective putting technique improvement
Solution Approach 1:
The system segments the measurement process into multiple independent sensor units, each responsible for detecting specific parameters (ball position, putter position, light interruption events). This modular segmentation allows comprehensive measurement without requiring a single complex measurement system, thereby improving measurement precision while managing device complexity through distributed sensing.
Solution Approach 2:
The sensor units serve multiple functions: detecting ball position, detecting putter position, measuring putting speed, and timing tempo intervals. By making the sensor system multi-functional, the patent achieves comprehensive measurement capabilities without proportionally increasing device complexity, as the same hardware infrastructure supports multiple measurement objectives.
2Loss of information
If multiple sensor units are installed to measure putter tempo and speed, then the information quality improves, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensor units into an integrated measurement system where first and second sensor units work together to detect both ball and putter parameters. By merging these sensing functions into a coordinated system with centralized control, the patent reduces information loss while preventing device complexity from becoming unmanageable through systematic integration.
Solution Approach 2:
The system implements feedback by processing signals from multiple sensor units to calculate derived parameters such as putting speed and tempo. This feedback mechanism transforms raw sensor data into meaningful performance metrics, improving information quality while using software-based processing rather than additional hardware to manage complexity.
3Productivity
If the system measures tempo and putter speed in addition to ball speed, then the productivity of putting practice improves, but the device complexity increases
Solution Approach 1:
The system performs preliminary measurement of putter position and ball position before the actual putting action occurs. By pre-positioning sensor units and establishing detection baselines before putting practice begins, the system enables immediate tempo and speed calculations without requiring additional processing complexity during active use, thereby improving productivity while managing device complexity.
