Power-Free Clay Thrower Auto-Reset Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clay throwers require manual operation to reset the throwing arm and need frequent loading of clay targets, and previous power-assisted designs are inefficient, costly, and environmentally unfriendly due to motor usage.
Innovation Solution
A power-free step auto reset clay thrower utilizes an elastic member to automatically return the throwing arm to its original position, eliminating the need for motors and associated components, using a system where the elastic restoring energy drives the throwing arm to throw and reset without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a motor is used to return the throwing arm, then the throwing arm can be automatically reset, but electricity is wasted and environmental protection principles are violated
Solution Approach 1:
The elastic member serves itself by automatically storing energy during the throwing motion and then releasing that energy to return the throwing arm to its initial position, eliminating the need for external power sources or control systems
Solution Approach 2:
The elastic member undergoes periodic deformation - being compressed or twisted during the throwing phase and then rebounding during the reset phase, creating a natural oscillating cycle that automates the return motion without additional energy input
2Extent of automation
If a mini motor and transmission components are installed, then the throwing arm can be returned automatically, but assembly and component costs increase
Solution Approach 1:
The invention extracts and eliminates the motor and transmission components from the system, replacing them with a purely elastic mechanical solution that uses the existing structural elements to achieve the same automatic return function
Solution Approach 2:
The elastic member serves multiple functions: it stores energy during throwing, provides the restoring force for automatic reset, and eliminates the need for separate motor and transmission components, thereby reducing overall system complexity and cost
3Device complexity
If manual operation is used to reset the throwing arm, then the structure remains simple, but operational convenience deteriorates
Solution Approach 1:
The elastic member automatically performs the reset function without requiring manual intervention, making the system serve itself by using the energy stored during the throwing motion to return the arm to its starting position

AI summary
A power free step auto reset clay thrower consisting of a base, a stepping rod, a support, a throwing arm holder, a throwing arm and an elastic member is disclosed. When the stepping rod is depressed, the throwing arm is forced by a first spring to move a link and a first linking member in turning the throwing arm forward for causing generation of a centrifugal force to throw a clay away from the throwing arm. When the throwing arm is thrown forward, the eccentric pivot joint stretches the elastic member. When the pedal is stopped, the elastic member restores the pedal, and the throwing arm is also returned to its original position where the rear side of the sidewall of the throwing arm is stopped by the top side of the trigger arm. Since there is no need to additionally install a motor for driving the throwing arm to restore the position, the invention has the advantages of saving power and environmental protection and can save motor assembly and component costs.
