Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a coil spring mechanism is used to launch the toy top, then the toy top can be launched with sufficient power, but the device becomes complex, large, and fragile
Solution Approach 1:
The patent extracts and eliminates the coil spring mechanism from the launcher, retaining only the essential function of launching the toy top. The launching power is achieved through a simpler lever arm mechanism that rotates a barrel with screw threads, removing the complex and fragile coil spring while maintaining sufficient launching power.
Solution Approach 2:
The patent replaces the coil spring mechanical system with a lever arm and screw thread mechanism. The lever arm rotates the barrel, and the screw threads on the barrel engage with the launcher adapter to propel the toy top forward, substituting a simpler mechanical system for the complex coil spring system.
2Power
If a long coil spring is used to provide sufficient power, then the toy top can be launched effectively, but the rewinding time becomes very long
Solution Approach 1:
The patent removes the coil spring entirely from the system, eliminating the time-consuming rewinding operation. The lever arm mechanism can be quickly reset by simply returning the lever arm to its initial position, allowing for rapid successive launches without the delays associated with rewinding a long coil spring.
3Power
If a rotatable shaft supporting the coil spring is used, then the toy top can be launched, but the mechanism becomes fragile to rough handling
Solution Approach 1:
The patent extracts and removes the long rotatable shaft that supported the coil spring, eliminating the source of fragility. The new design uses a more compact lever arm mechanism that rotates within a housing, making the overall structure more robust and resistant to rough handling by children.
4Device complexity
If a simple launcher design is used, then the device is robust and easy to manufacture, but it may not provide sufficient launching power
Solution Approach 1:
The patent uses a lever arm mechanism that rapidly rotates the barrel through a limited angular range, delivering a concentrated impulse to the toy top. This rushing through of the launching action in a short time provides sufficient power despite the simplicity of the overall structure.
Solution Approach 2:
The patent changes the parameters of the launching mechanism by using a lever arm with specific length ratios and screw thread pitch, optimizing the mechanical advantage and rotational speed to generate sufficient launching power from a simple structure.

Function Achieved in This Case
The toy top launcher provides a simple, robust, and compact mechanism for launching toy tops with a trajectory that combines vertical and horizontal motion, allowing for prolonged spinning and efficient use in battle scenarios.
Implementation Method 1
the barrel comprises a first screw thread configured for cooperating with a mating screw thread on the launcher adapter... the lever arm is rotated, causing the launcher adapter to be pushed along a longitudinal axis of the barrels, and being rotated by the mating screw threads
