Ball-Loading Device With Rotating Bracket For Free-Fall Experiments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional free-fall experiments require manual collection of balls, leading to inefficiency and potential errors, especially in repeated experiments, as operators must gather and reposition balls manually, increasing operational tediousness and the risk of mistakes.
Innovation Solution
A ball-loading device with an inlet tube, shell, and rotating bracket system that automatically collects and loads balls in sequence after each free-fall motion, utilizing a baffle bar and baffle plate to control ball flow and a ball-transferring assembly with an elastic contact plate to transport balls back to the initial position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual collection of balls is used, then device complexity is reduced, but productivity decreases due to operator intervention required after each experiment
Solution Approach 1:
The device automatically collects and returns balls to the starting position without operator intervention. The rotating bracket with blocking parts self-regulates ball flow, and the ball-transferring assembly automatically retrieves balls from the collection position and places them back at the inlet, enabling the system to service itself throughout the experimental process
Solution Approach 2:
The bracket is designed to rotate between different positions to dynamically control ball flow. The blocking parts on the bracket rotate into and out of blocking positions to control when balls are discharged from the shell, creating a dynamic system that adapts to different operational phases (experiment vs. collection modes)
2Loss of time
If manual gathering of balls is performed, then ease of operation is maintained, but loss of time increases due to repeated manual collection operations
Solution Approach 1:
The ball-transferring assembly is pre-positioned with the ball receiving bracket at the collection position and the ball-transferring mechanism ready to immediately retrieve balls when they reach the collection point, eliminating any idle time between ball completion and retrieval
Solution Approach 2:
The system maintains continuous operation where the bracket rotates to block the outlet during experiments, then automatically rotates to allow collection, and the ball-transferring assembly continuously moves balls from collection position back to inlet position without interruption or idle periods
3Productivity
If automated ball collection is implemented, then productivity increases, but device complexity increases due to additional mechanical components
Solution Approach 1:
The rotating bracket serves multiple functions: it blocks the ball outlet during experiments, rotates to allow ball collection, and works with the ball-transferring assembly to enable automatic ball return. The blocking parts on the bracket are multi-functional elements that control ball flow in different operational phases
Solution Approach 2:
The ball-transferring assembly combines the ball receiving bracket, catcher, and transferring mechanism into an integrated unit that performs collection and return operations. The contact plate with protruding part merges the triggering mechanism with the ball receiving structure, reducing the number of separate components

AI summary
The ball-loading device for free-fall experiments includes an inlet tube and a shell. The first end of the shell is connected to the inlet tube, and the shell has a ball channel. A ball outlet is located at the second end of the shell, with the first end of the inlet shell positioned higher than the second end. Additionally, a bracket is rotatably connected to the shell and has a first blocking part and a second blocking part. As the bracket rotates around the shell, the first blocking part is switched to block the ball outlet, or the second blocking part is switched to block the ball channel. This device provided by the present disclosure allows automatic loading and resetting of the balls used in free fall experiments, thereby improving experimental efficiency.
