Cam-Based Fold Locking Mechanism for Low-Force Gaming Table Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional recreational basketball games require substantial space for play and storage, with existing quick-locking mechanisms being complex, requiring high forces, and posing safety concerns due to pinch points, especially for single users and children.
Innovation Solution
A self-contained easy fold locking mechanism using a hinge bar, tab connector, and release section that allows for secure connection and easy disassembly with minimal force, providing visual confirmation of the locking state and reducing the risk of injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional quick-locking mechanisms (snap clamps, spring-loaded devices) are used to secure structural components, then assembly and disassembly efficiency is improved, but device complexity increases and high forces are required for operation
Solution Approach 1:
The patent combines multiple functions into a single integrated locking mechanism. The cam member integrates the locking engagement, force application, and visual indication functions into one component that works with a simple tab and slot feature, eliminating the need for separate snap clamps, spring plungers, or indicator mechanisms while maintaining quick-locking efficiency.
Solution Approach 2:
The cam member serves multiple functions simultaneously: it provides the locking engagement through cam surface interaction with the tab, applies force to secure components through its rotation, and provides visual indication of locked state through its position relative to the slot. This multi-functionality reduces overall device complexity while maintaining productivity.
2Strength
If metal-on-metal quick-lock mechanisms are used for high-strength durability, then strength and reliability are improved, but the force required for engagement and disengagement increases significantly
Solution Approach 1:
The patent replaces traditional metal-on-metal spring-loaded plungers with a cam-based mechanical system that uses geometric leverage. The cam surface converts rotational motion into linear locking force, providing high-strength engagement with lower operational force requirements. The cam profile is designed to distribute forces efficiently, reducing peak forces needed by the user while maintaining durable metal-to-metal contact during the actual locking engagement.
3Ease of operation
If spring-loaded retractable plungers are used for quick-locking, then ease of operation is improved, but pinch points are created that pose safety risks to users
Solution Approach 1:
The patent extracts the hazardous spring-loaded plunger component entirely from the system and replaces it with a cam-based mechanism. The cam member rotates externally to engage and disengage the locking tab, eliminating enclosed spring mechanisms and pinch points while maintaining ease of operation. Users interact with the external cam surface rather than compressed springs, removing the safety hazard.
4Ease of operation
If visual confirmation of locking state is provided through transparent or translucent materials, then ease of operation is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent introduces a visual intermediary element (such as a colored indicator, window, or marker on the cam member or housing) that shows the locking state without requiring the entire component to be transparent or translucent. This intermediary provides clear visual feedback while allowing the main structural components to remain opaque for strength and manufacturing simplicity, thus resolving the contradiction between visual confirmation and manufacturing ease.

AI summary
The present disclosure relates to a support system for a gaming table including a first support bar of a gaming-table support, a second support bar of a gaming-table support, a third support bar of a gaming-table support, and a gaming-table support locking apparatus. The third support bar has an arcuate shape and is in a pivotable connection with the second support bar. The gaming-table support locking apparatus includes a first locking bar and a second locking bar. The second locking bar is configured to be in one of two states of being: a first state that allows the third support bar to rotate with respect to the second support bar; and a second state that prevents the third support bar to rotate with respect to the second support bar.
