Trampoline Jumping Mat Sensor Layout for Precise User Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trampoline sensor systems lack accuracy and resolution, making it difficult to precisely determine the user's location on the jumping mat and provide detailed motion analysis.
Innovation Solution
A sensor arrangement with first and second sensor lines forming crossing points, insulated from each other, creates a high-resolution matrix on the jumping mat, allowing precise user positioning and motion analysis through capacitive detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contact sensors or acceleration sensors are used to detect jumps and forces, then basic jump counting is achieved, but measurement precision and resolution remain insufficient for accurate user positioning
Solution Approach 1:
The sensor arrangement is segmented into multiple sensor lines with individual sensor elements distributed across the jumping mat surface. Each sensor element independently measures local acceleration, and the combination of multiple segmented sensors achieves high-resolution positioning without requiring a single complex sensor system.
Solution Approach 2:
The patent transitions from one-dimensional jump counting to two-dimensional spatial resolution by arranging sensor lines in multiple directions (e.g., radial and circumferential patterns). This dimensional expansion enables precise determination of user position on the mat surface while maintaining manageable sensor complexity through systematic geometric distribution.
2Measurement precision
If sensor lines are placed directly on the jumping mat, then high-resolution measurement is achieved, but the sensor lines are exposed to mechanical overload and damage
Solution Approach 1:
The sensor lines are nested within protective layers or integrated into the mat structure in a way that embeds them without exposing them to direct mechanical stress. The sensor elements are positioned within the mat's layered construction, allowing the mat material to protect the sensors while still enabling accurate motion detection through the protective layers.
3Area of stationary object
If border regions of the jumping mat are included in the sensor matrix, then complete coverage is achieved, but the number of sensors increases and border regions are seldom jumped upon
Solution Approach 1:
The sensor arrangement applies local quality by concentrating sensor elements in the central jumping region where user activity is most frequent, while reducing or omitting sensors in border regions that are seldom jumped upon. This non-uniform distribution optimizes measurement precision where it is most needed while minimizing the total sensor quantity and system complexity.

Implementation Method 1
The sensor arrangement is preferably a capacitive sensor arrangement. During a measurement process, the transmission line transmits field lines to the reception line at fixed time intervals, and these are deflected when the foot (or some other part of the body) approaches.
Implementation Method 2
During a measurement process, the transmission line transmits field lines to the reception line at fixed time intervals, and these are deflected when the foot (or some other part of the body) approaches.
