Toy Identification Carrier Magnet Positioning for Sensor Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toys for replaying music or spoken stories with identification carriers often experience reduced recognition accuracy due to the presence of additional magnets, which disrupt the magnetic field detection, especially when the magnet is closer to the surface than the identification carrier.
Innovation Solution
The identification carrier is designed with a magnet positioned closer to the standing surface than the identification, allowing for optimal placement and reduced interference with sensor detection, ensuring accurate recognition and interaction with the toy's sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the magnet is positioned closer to the standing surface than the identification, then the identification carrier can be securely placed on the surface, but the recognition accuracy is reduced due to magnetic field disruption
Solution Approach 1:
The patent introduces a vertical dimension to the arrangement of magnet and identification, positioning them at different heights relative to the standing surface. This spatial separation in the vertical dimension allows the magnet to provide holding force while the identification remains accessible to the sensor for accurate recognition.
Solution Approach 2:
The patent applies different spatial positions to different components: the magnet is positioned closer to the standing surface for optimal holding force, while the identification is positioned farther away for optimal sensor detection. This local differentiation of component positions resolves the contradiction between holding force and recognition accuracy.
2Measurement precision
If the magnet is positioned farther from the standing surface than the identification, then the magnetic field disruption is minimized, but the holding force is reduced
Solution Approach 1:
The patent utilizes the vertical dimension to separate the optimal positions for the magnet and identification. The magnet can be positioned at a distance that provides sufficient holding force, while the identification is positioned at a different vertical level that optimizes sensor detection, eliminating the need to compromise either function.
Solution Approach 2:
Different spatial zones are optimized for different functions: the region closer to the standing surface is optimized for magnetic holding force, while the region farther from the surface is optimized for identification detection. This local optimization of different spatial zones resolves the contradiction.
3Device complexity
If a surface normal to the standing surface passes through both the magnet and the identification, then the structural alignment is simplified, but the recognition is disrupted
Solution Approach 1:
The patent introduces asymmetry in the vertical positioning of the magnet and identification relative to the standing surface. Instead of both components lying on the same plane perpendicular to the surface, they are positioned at different heights, creating an asymmetric arrangement that prevents the surface normal from passing through both components simultaneously.
Solution Approach 2:
The patent moves the relationship between magnet and identification from a two-dimensional planar arrangement to a three-dimensional spatial arrangement. By positioning them at different vertical levels, the system eliminates the problem of the surface normal passing through both components while maintaining simple structural alignment through vertical stacking.
