Wearable Band Rotatable Disc for Referee Possession Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Referees in sporting events face challenges in quickly and efficiently determining which team has the next possession during a jump ball, often requiring attention diversion from the game or reliance on third-party tracking.
Innovation Solution
A wearable wristband with a rotatable disc system, featuring two visually distinct sides that can be rotated to indicate the team with the next possession, allowing referees to maintain focus on the game without interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the referee relies on a third party to track possession, then tracking accuracy is improved, but game flow efficiency deteriorates due to communication delays and potential errors
Solution Approach 1:
The referee performs possession tracking independently using their own cognitive resources and the wearable device, eliminating dependence on external third parties. The device provides visual cues that the referee can interpret autonomously, enabling self-sufficient tracking that maintains both accuracy and game flow efficiency
2Device complexity
If the referee attempts to track possession mentally, then device complexity is reduced, but reliability deteriorates due to human error and attention lapses
Solution Approach 1:
The wearable device serves as an intermediary between the possession state and the referee's perception. It translates complex possession tracking information into simple visual cues (disc orientation) that the referee can reliably interpret, enhancing trustworthiness without requiring the referee to perform complex mental tracking
3Measurement precision
If the referee takes attention away from the game to track possession, then possession tracking accuracy is improved, but game monitoring quality deteriorates
Solution Approach 1:
The wearable device uses visual differentiation (two visually distinct sides of a disc) to encode possession information. The referee can quickly scan the disc orientation with peripheral or brief attention, obtaining accurate possession information without sustained focus, thereby maintaining attention on the game while ensuring accurate tracking
4Measurement precision
If breaks in play are introduced to track possession, then possession tracking accuracy is improved, but productivity deteriorates due to lost game time
Solution Approach 1:
The wearable device continuously displays possession information in real-time throughout the game. The referee can obtain possession information at any moment without waiting for breaks or stopping play, as the information is proactively presented and continuously updated during game flow

AI summary
Disclosed is a wearable band that includes a strap extending between a first end and a second end and an axle extending between and attached to each of the first end and the second end, the axle including a smaller cross section than the strap. The wearable band includes a first disc portion including a first body, a first channel, a first groove and a first protrusion, and a second disc portion including a second body, a second channel, a second groove and a second protrusion. The first disc portion and the second disc portion are connected such that the first protrusion is located within the second groove and the second protrusion is located within the first groove. The first and second channels are aligned, and the axle is located within the aligned first and second channels. A method and kit are further disclosed.
