Solution Overview

Problem

Existing multiple dwelling house interphone systems fail to simplify the process of deleting dweller information from communication management devices, particularly when using mobile phones, leading to incomplete erasure of data during transitions.

Innovation Solution

A system allowing deletion of information through a mobile phone application that displays and manages registered information, enabling easy recognition and removal of unnecessary data via a VOIP-based communication management device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If information deletion is performed through initialization functions in the interphone system, then registered information can be cleared, but the information in the communication management device remains undeleted requiring complex manual operations

Engineering Contradiction:
Improvecompleteness of information deletionVSAvoidsimplicity of deletion operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent merges the deletion operations across multiple devices (interphone system and communication management device) into a single unified action. When the owner performs an initialization operation on their mobile phone, the system automatically coordinates to delete information from both the interphone system and the communication management device simultaneously, eliminating the need for separate manual deletion steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mobile phone application serves as an intermediary that mediates the deletion process between the owner and the communication management device. The app receives the initialization command from the owner and automatically transmits the deletion instruction to the communication management device, simplifying the operation for the owner while ensuring complete information deletion.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the system stores dweller information in the communication management device for mobile phone communication, then remote communication capability is enabled, but the deletion process becomes more complex and information is easily left undeleted

Engineering Contradiction:
Improvemobile phone communication capabilityVSAvoidcomplexity of information management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements self-service automation where the mobile phone application automatically manages the information deletion process without requiring manual intervention. When the owner initializes their interphone system, the application autonomously identifies and deletes the corresponding information from the communication management device, making the system adaptable to mobile communication while maintaining simple operation.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If initialization functions are provided for deleting dweller information, then information can be erased from the interphone system, but further operations are required to delete information from the communication management device

Engineering Contradiction:
Improveease of system setupVSAvoidtime required for complete information deletion
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent implements preliminary action by designing the mobile phone application to automatically prepare and execute the deletion of information from the communication management device as part of the initialization process. The application pre-configures the deletion mechanism and executes it automatically when the owner performs initialization, eliminating the need for additional manual deletion operations and saving time.

Inventive Principle:
Principle #10Preliminary action

AI summary

OBJECT Information about a mobile phone registered on a communication management device can be erased through a simple operation, when there is information needing erasure. SOLUSION A multiple dwelling house interphone system includes a communication management device 6 that controls communication between the collective entrance machine 1 and the mobile phone 5. The communication management device 6 relays the communication to the mobile phone 5 registered as a calling destination of the collective entrance machine 1 to be linked to the dwelling room master device 2 using a predetermined application based on a VOIP. When a predetermined registration operation to allow communication with the communication management device 6 based on the VOIP is performed to link the mobile phone 5 to the dwelling room master device 2, information list on mobile phones 5 already registered relative to the dwelling room master device 2 as a link target is transmitted from the communication management device 6 having accepted the registration in addition to an application for a download, and the mobile phone 5 that has downloaded the application displays the information list on a display section of the mobile phone.
