Top Toy Shaft Locking Structure for Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing top toys experience energy loss and difficulty in landing in a desired position due to a large landing impact and bouncing, as the shaft cannot be pushed deeper into the shaft support unit when gripped by the elastically locking part.
Innovation Solution
The shaft is configured to move between a first and a second position in the shaft hole, with an elastically locking part that deforms upon impact and returns to the first position using stored elastic force, absorbing impact energy and preventing bouncing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shaft is held firmly at the first position by the elastically locking part, then the top toy maintains stable rotation, but the shaft cannot be pushed deeper into the shaft support unit when landing impact occurs
Solution Approach 1:
The elastically locking part is designed to dynamically switch between two states: (1) gripping the constricted part to hold the shaft at the first position for stable rotation, and (2) elastically deforming to allow the shaft to move to the second position when landing impact occurs. This dynamic adaptability resolves the contradiction between firm holding and impact absorption.
Solution Approach 2:
The elastic force parameter of the elastically locking part changes based on external impact conditions. During normal rotation, the elastic force maintains gripping to ensure stability. During landing impact, the elastic force temporarily decreases to allow shaft movement, then restores to return the shaft to the first position, thus adapting to different operational states.
2Reliability
If the shaft cannot move deeper into the shaft support unit during landing, then the elastically locking part maintains gripping, but the top toy experiences large landing impact and bouncing causing energy loss
Solution Approach 1:
The elastically locking part serves as a beforehand cushioning mechanism that absorbs landing impact energy through elastic deformation. When the top toy lands, the elastic structure deforms to cushion the impact, preventing direct transmission of shock to the shaft and reducing bouncing, thereby minimizing rotational energy loss.
Solution Approach 2:
The landing impact, which is initially harmful causing bouncing and energy loss, is converted into a beneficial effect by utilizing the elastic deformation of the elastically locking part. The impact force causes the elastic structure to deform and store energy, which then returns to propel the shaft back to its original position, transforming the harmful impact into a useful energy storage and release mechanism.
3Stability of the object's composition
If the shaft is held at the first position by the elastically locking part, then rotation stability is maintained, but the top toy bounces upon landing due to inability to absorb impact
Solution Approach 1:
The system dynamically adapts to landing impact by allowing temporary shaft movement to the second position during impact, then returning to the first position. This dynamic response converts the rigid stability structure into an adaptable system that can absorb impact while maintaining overall rotation stability.
Solution Approach 2:
The elastically locking part acts as an intermediary between the shaft and the external impact force. It mediates the impact by deforming elastically, absorbing the shock, and then returning the shaft to its stable position, thus protecting the rotation stability from the harmful landing impact.
