Interphone Master Device Autonomous Speech Path Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multiple dwelling house interphone systems do not allow speaking between dwelling units when multiple dwelling room master devices are installed in one unit, and one device is already busy with another unit, limiting the effective use of these devices and requiring a controller for communication management.
Innovation Solution
The system includes dwelling room master devices with ID information storage, calling operation, and master device speech control sections, enabling calling and speaking with other units even when one device is busy, and incorporating a permitted dwelling unit storage section to restrict unauthorized calls, eliminating the need for a separate controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple dwelling room master devices are installed in one dwelling unit, then the ability to simultaneously form speech paths with other dwelling units is improved, but the system complexity increases and requires a controller for communication management
Solution Approach 1:
Each dwelling room master device autonomously performs calling control operations including obtaining master device ID information from storage, transmitting call signals to destination devices, and forming speech paths without requiring external controller intervention. The device uses its own ID information storage section and calling operation section to independently manage communications.
Solution Approach 2:
The system divides communication management functions into independent segments at each dwelling room master device level, with each device having its own ID information storage section, calling operation section, and master device speech control section, eliminating the need for a centralized controller.
2Productivity
If multiple dwelling room master devices are installed in one dwelling unit, then the effective use of devices is improved, but unauthorized calls from other units cannot be restricted
Solution Approach 1:
The permitted dwelling unit storage section pre-stores identification information of authorized dwelling units before any calling operation occurs. The master device speech control section checks this stored information against the destination of outgoing calls to prevent unauthorized communications.
Solution Approach 2:
The system implements a feedback mechanism where the master device speech control section continuously monitors calling operations and compares destination information against the permitted dwelling unit storage section, providing real-time control to block unauthorized calls while allowing permitted communications.
3Ease of operation
If a controller is installed to manage communication between devices, then the control of speech paths is improved, but the device complexity and cost increase
Solution Approach 1:
Each dwelling room master device autonomously performs calling control operations including obtaining master device ID information from storage, transmitting call signals to destination devices, and forming speech paths without requiring external controller intervention. The device uses its own ID information storage section and calling operation section to independently manage communications.
Solution Approach 2:
The dwelling room master device integrates multiple functions including ID information storage, calling operation control, speech path management, and permitted unit verification into a single multi-functional device, eliminating the need for separate dedicated controller components.

AI summary
A multiple dwelling house interphone system includes a collective entrance machine and dwelling room master devices. When a calling operation section is operated and a dwelling unit number of a calling destination is input, a master device speech control section of the dwelling room master device of the dwelling unit including a plurality of dwelling room master devices performs a calling control of transmitting a call signal to the dwelling room master device of the calling destination having its master device ID, and subsequently forming a speech path when a response operation of the dwelling room master device of the calling destination is performed. The calling and speaking to the other dwelling unit are allowed even in a state where another dwelling room master device of the dwelling unit itself has formed a speech path with the dwelling room master device of the other dwelling unit.
