Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for determining whether a sports object has passed a goal plane lack sufficient spatial and temporal resolution, especially when the object is moving at high velocities, leading to uncertainty in scoring decisions and requiring expensive and complex installations.
Innovation Solution
A system with sectioned stationary conductors producing distinct electromagnetic fields allows for separate detection data analysis from different parts of the goal plane, enabling precise determination of the object's passage without encircling the entire plane, and equipping the object with radio wave emitters and sensors for improved data processing and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a position determining system is used to provide reliable determination of whether the object has passed the goal plane, then measurement precision is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent divides the goal plane detection into multiple independent sensor sections arranged along the goal line. Each sensor section independently detects objects passing through its specific zone, allowing the system to achieve high measurement precision without requiring a single complex encircling system. The sensors are segmented into multiple discrete units that can be independently controlled and processed.
Solution Approach 2:
The patent extracts the detection function from a complete encircling system and applies it only at the critical goal line area. By using sensors positioned specifically along the goal line rather than encircling the entire goal plane, the system achieves sufficient precision for scoring decisions while reducing overall system complexity and cost.
2Measurement precision
If the update rate of position determination is increased to handle high velocity objects, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent employs preliminary action by having sensors continuously monitor the goal line area at high update rates, ready to detect and record the exact moment an object passes through. The sensors are pre-positioned and continuously sampling data, so when an object appears, the system immediately captures the passage event without requiring complex real-time processing or additional hardware.
3Measurement precision
If a single encircling detection system is used for the goal plane, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the detection system into multiple independent sensor units positioned along the goal line rather than using a single encircling system. Each sensor section independently detects objects in its zone, achieving sufficient spatial resolution for accurate goal determination while reducing the complexity of any individual component and the overall system architecture.

AI summary
A system is disclosed for detection of whether a movable object, such as a sports object, e.g. a football or an ice hockey puck, has passed goal plane. It is known to encircle the goal plane with conductors (1, 2, 3, 4) to produce an electromagnetic field to excite signal emitter means in the movable object, alternatively detect the signal emitted by the emitter means. With the present invention these circuits are sectioned into a plurality of separate circuits, which provides an improved spatial resolution of the system in particularly when the movable object is close to the conductors.
