Solution Overview

Problem

Current buckle devices for amusement devices, such as motion simulators, are difficult to use in dark environments, cannot easily confirm the locked state without physical inspection, pose risks for germ transmission, have complex structures that complicate assembly, and may be accidentally pressed, leading to occupant unease.

Innovation Solution

A buckle device with a main body, latch unit, fastening unit, electromagnetic unit, and control unit that includes a magnetic bolt detection module and display module, allowing the buckle to display its locked state through lighting effects, enabling confirmation without physical contact and simplifying assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a conventional buckle device is used in a dark environment, then the movie presentation quality is improved, but the occupant cannot perceive the buckle device position

Engineering Contradiction:
Improvedark environmentVSAvoidperception of buckle device position
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The patent applies light-emitting elements that change color or emit different colors to indicate different states of the buckle device. A first color (e.g., green) indicates the tongue element is properly inserted and locked, while a second color (e.g., red) indicates the tongue element is not inserted or is in a released state. This allows occupants to easily perceive the buckle device status in dark environments without compromising movie presentation quality.

Inventive Principle:
Principle #32Color changes

2Reliability

If staff physically inspect the buckle device to confirm locked state, then the locked state can be confirmed, but germ transmission risk increases

Engineering Contradiction:
Improveconfirmation of locked stateVSAvoidgerm transmission
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical inspection method (staff physically touching and pressing the buckle device) with an optical detection system. Light-emitting elements and light-receiving elements detect the position and state of the tongue element non-contactly, transmitting state information to a control unit that displays the locked state. This eliminates the need for physical contact between staff and occupants, preventing germ transmission while maintaining reliable confirmation of the locked state.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If electromagnetic rods interfere with vertical disks to prevent pressing, then the pressing body cannot be pressed, but the structure becomes complex

Engineering Contradiction:
Improveprevention of accidental pressingVSAvoidstructure with multiple grooves and protrusions
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and separates the electromagnetic locking mechanism from the vertical disk structure. Instead of incorporating electromagnetic rods within the complex vertical disk grooves and protrusions, the electromagnetic module and electromagnetic rod are positioned to interact with the tongue element directly. This simplifies the overall structure by removing the need for multiple grooves and protrusions in the vertical disks, while still achieving reliable prevention of accidental pressing through the electromagnetic holding force on the tongue element.

Inventive Principle:
Principle #2Taking out (Extraction)
