Booth Door Locking Control via Terminal Detection

Solution Overview

Problem

Users may encounter difficulty re-entering a booth that has automatically locked its door, even if they exit without their user terminal, leading to inconvenience in accessing reserved spaces.

Innovation Solution

Implementing an information processing system with a space management server and user terminals that manage reservations and door locking conditions, allowing the door to remain unlocked if closed within the reservation period or when specific conditions such as unoccupied states are met, enabling re-entry without the user terminal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the door is locked automatically when closed, then security and automatic locking function are improved, but user convenience for re-entry is worsened

Engineering Contradiction:

Improveautomatic locking functionVSAvoiduser convenience for re-entry

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The locking mechanism transitions from a static automatic lock to a dynamic system that adapts its state based on real-time conditions. The door lock can be locked or unlocked automatically depending on whether the terminal device is detected inside the booth, allowing the system to respond flexibly to user presence and enable convenient re-entry when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback by continuously monitoring the position of the terminal device relative to the booth through detection means. This feedback loop allows the control means to make informed decisions about door locking status, ensuring the door remains unlockable for re-entry when the terminal is outside while maintaining security when the terminal is inside.

Inventive Principle:

Principle #23Feedback

AI summary

A booth includes an openable door and a locking mechanism that locks the door. The door is locked in a case where the door is closed, and the door is not locked in a case where a predetermined condition is satisfied.
