Solution Overview

Problem

Conventional chair locking mechanisms for gaming devices are cumbersome, costly, and interfere with floor space and maintenance, while also posing safety risks due to their mobility and complex attachment systems, which are not universally required by all gaming establishments.

Innovation Solution

A quick-release low-profile locking mechanism integrated into a chair sled that securely couples a gaming chair to a gaming device, featuring a latching unit with a spring mechanism and a latch cover, allowing for easy attachment and detachment with a tool, reducing the need for additional manufacturing costs and improving safety by minimizing footroom interference and preventing unauthorized detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mechanical latch system is used to secure the chair to the gaming device, then the chair attachment is reliable and secure, but the device complexity and manufacturing cost increase due to additional parts and installation requirements

Engineering Contradiction:
Improvechair attachment securityVSAvoidlatch system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the mechanical latch system from the gaming device entirely and relocates it to the chair sled. The sled body includes a cavity with a latch mechanism that engages with a connector on the gaming device base, eliminating the need for latches in the device itself and reducing overall system complexity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The chair sled acts as an intermediary component between the chair and the gaming device. It provides the attachment functionality through its integrated latch mechanism while maintaining a simple interface with the gaming device, thus resolving the contradiction between security and complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If a raised portion is added to the connection point to facilitate latch pin or hook attachment, then the latch mechanism can be properly positioned, but it interferes with player foot room and is incompatible with low profile gaming devices

Engineering Contradiction:
Improvelatch installation facilitationVSAvoidconnection point height
Core Design Contradiction:
Ease of manufactureVSLength of stationary object

Solution Approach 1:

Instead of raising the connection point on the gaming device, the patent inverts the approach by placing the latch mechanism in the chair sled and having it engage with a connector on the gaming device base. This allows the latch to be positioned at an appropriate height without interfering with foot room or compatibility with low profile devices

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If conventional mechanical latches are used to retain the chair, then the chair is securely attached, but the entire game must be taken out of service for repair if there is a mechanical problem with the latch system

Engineering Contradiction:
Improvechair retention securityVSAvoidlatch system repair accessibility
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The patent segments the attachment system by placing the latch mechanism in the removable chair sled rather than in the gaming device. This allows the sled to be easily removed and replaced if the latch mechanism fails, eliminating the need to take the entire game out of service for repair

Inventive Principle:
Principle #1Segmentation

4Object-affected harmful factors

If chairs are physically attached to gaming devices to prevent unauthorized removal, then player safety is improved, but the attachment system becomes cumbersome and difficult for casino personnel to remove

Engineering Contradiction:
Improveunauthorized chair removal preventionVSAvoidchair attachment removal difficulty
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent implements a dynamic attachment system where the latch mechanism can be easily engaged and disengaged by casino personnel using a tool through an opening in the sled body. This allows the chair to be securely attached to prevent unauthorized removal while remaining easily removable by authorized personnel for maintenance or reconfiguration

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides a cost-effective, safe, and efficient way to attach gaming chairs to devices, reducing manufacturing costs, enhancing player safety, and simplifying maintenance and reconfiguration processes without the need for universal latching systems, while maintaining compatibility with low-profile gaming devices.

Implementation Method 1

A latching unit is disposed in the cavity of the sled body along with a spring that is configured to hold the latching unit in a locked position

Methodology Applied
Scientific EffectSpring mechanism: Spring

AI summary

Provided in embodiments of the present invention is a chair sled locking mechanism for use with a gaming device. In one example embodiment, a chair sled includes a sled body having a chair attachment connector disposed at a first end of the sled body and a cavity disposed at a second end of the sled body. A latching unit is disposed in the cavity of the sled body along with a spring that is configured to hold the latching unit in a locked position. A latch cover covers the cavity of the sled body. At least one of the latch cover or sled body includes an opening that allows an operator to manipulate the latching unit to an unlocked position.
