Spinning Top Rotation Rate Detection with Attachment Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic spinning-top game devices inaccurately calculate the number of rotations if the spinning top is not properly attached, leading to erroneous detections.
Innovation Solution
A rotation-rate detector system that includes a launcher with a detachment detector to ensure accurate attachment of the spinning top, a counter to count rotations, a clock to measure time, and a rate calculator to calculate the rotation rate based on these measurements, preventing erroneous detections by only initiating detection after the spinning top is securely attached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rotation detector continuously detects rotations without attachment detection, then the detection system is simple, but erroneous rotation rate calculations occur when the spinning top is not attached
Solution Approach 1:
The detachment detector checks attachment status before the rotation detection begins. This preliminary verification ensures that the system only performs rotation measurements when the spinning top is properly attached, preventing erroneous calculations while maintaining a relatively simple overall system architecture.
2Adaptability or versatility
If the detachment detector is integrated into the launcher, then the system structure is simplified, but the detector cannot be used with different launchers
Solution Approach 1:
The rotation detector and detachment detector are designed as separate, detachable modules from the launcher. This segmentation allows the detection system to be universally attached to different launcher types while maintaining functional integration during use, achieving versatility without excessive structural complexity.
3Ease of operation
If the detection switch is activated by the spinning top itself, then the attachment detection is automatic, but the rod mechanism adds structural complexity
Solution Approach 1:
The spinning top itself activates the attachment detection by pressing against the rod when properly attached. The system uses the presence and weight of the spinning top to trigger the detection switch, achieving automatic detection without requiring external power sources or complex sensing mechanisms.

Implementation Method 1
a spring that urges the rod with a predetermined urging force in one direction along the axis
Implementation Method 2
one end of the rod is urged by the upper surface of the spinning top attached to the launcher such that the rod moves in the other direction and turns on the detection switch

AI summary
An object of the present invention is to provide a rotation-rate detector for a spinning top with minimum erroneous detections. A rotation-rate detector (information logger 100) detects a rotation rate of a spinning top 300 and is fixed to or detachably attached to a launcher 200. The launcher 200 applies a rotational force to the spinning top 300 attached to the launcher 200 to launch the spinning top 300. The rotation-rate detector includes a detachment detector 130 that detects detachment and attachment of the spinning top 300. The rotation rate of the spinning top 300 is detected after the detachment detector 130 detects attachment of the spinning top 300.
