Smart Golf Ball Structure for Impact-Protected Flight Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf balls are vulnerable to external impacts and provide unreliable data on hitting direction and force due to component gaps and inaccurate pressure sensor placement, hindering precise putting practice and swing correction.
Innovation Solution
A smart golf ball with a protection cover composed of first and second protection covers, a shock-absorbing member, and a control unit that includes sensors to collect and transmit detailed putting ball flight information, including hit point, speed, rotation, slip, trajectory, and spacing angle, through a user terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is inserted in the cover that corresponds to the outer shell of the golf ball, then the signal transmission from the transmission chip to the smartphone is smooth, but the golf ball becomes very vulnerable to external impacts
Solution Approach 1:
The patent applies beforehand cushioning by inserting a shock-absorbing member between the cover and the outer shell. This shock-absorbing member is positioned to cushion external impacts before they reach the antenna and internal components, thereby protecting the signal transmission system while maintaining the antenna's exposure for communication.
2Ease of manufacture
If the buffer and the capsule, and the capsule and the core are configured in a simple bonding method, then the manufacturing process is simple, but gaps are formed between the components when the ball is hit by a force over a predetermined level
Solution Approach 1:
The patent applies composite materials by using a multi-layer structure consisting of a buffer layer, a capsule layer, and a core layer. Each layer is made of different materials with specific properties that, when combined, provide both ease of manufacture and reliable bonding. The buffer layer absorbs impact forces, preventing gaps from forming at the bonding interfaces between layers.
3Device complexity
If multiple pressure sensors are formed only on a predetermined surface, then the device complexity is reduced, but precise data on the trajectory information cannot be provided when impact is not accurately applied to the sensor positions
Solution Approach 1:
The patent applies segmentation by dividing the sensor system into multiple independent pressure sensors positioned at different locations on the golf ball. Instead of using a single complex sensor array, the patent uses multiple simple sensors strategically placed to detect impacts from various directions, thereby achieving precise trajectory measurement without excessive device complexity.
