Door-Mounted Cup And Ball Assembly With Movable Support Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cup and ball devices lack versatility and practicality for mounting on doors, limiting their accessibility and usability in testing user aim and skill.
Innovation Solution
A cup and ball device with a mounting bracket that can be positioned on a door, featuring a support arm extending downwardly, a ring on a horizontal plane, and a tether system allowing users to toss a ball into the ring, enhancing user interaction and skill testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device is mounted on a door, then accessibility and usability are improved, but door operation may be obstructed
Solution Approach 1:
The support arm is designed to be movable relative to the mounting bracket, allowing it to swing outward when the door opens and return to its playing position when the door is closed. This dynamic adjustment eliminates obstruction to door operation while maintaining accessibility when the door is closed.
Solution Approach 2:
The device is divided into separate components: a stationary mounting bracket attached to the door, and a movable support arm that can independently adjust its position. This segmentation allows the mounting structure to remain fixed while the playing component moves, resolving the conflict between door operation and device accessibility.
2Ease of manufacture
If the device structure is simplified for door mounting, then ease of installation is improved, but mounting stability may deteriorate
Solution Approach 1:
The mounting system is segmented into a separate mounting bracket with door-slot receivers and the main device body. This allows the bracket to be specifically designed for secure door attachment while keeping the overall device simple and easy to install.
Solution Approach 2:
The mounting bracket acts as an intermediary component between the door and the cup-and-ball device. It provides specialized door-slot receiving features that ensure stable mounting, while the rest of the device remains simple and easy to assemble.

AI summary
A cup and ball assembly includes a mounting bracket that has a door slot thereby facilitating the mounting bracket to be positioned on a door in a building. A support arm is coupled to the mounting bracket and the support arm extends downwardly along the door and away from the door when the mounting bracket is positioned on the door. A ring is coupled to the support arm and the ring lies on a horizontal plane when the mounting bracket is positioned on the door. A stub arm is coupled to support arm and an extension arm insertably receives the stub arm for removably attaching the extending arm on the stub arm. A tether is disposed on the extension arm and a ball is coupled to the tether thereby facilitating the ball to be thrown toward the ring by a user to test the user's aim and skill.
