Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless intercom systems for home security require multiple device installations and are limited by the need for hard wiring to a power source, making them inflexible and energy-intensive.
Innovation Solution
A wireless communication doorbell device equipped with a camera, microphone, speaker, button, sensor, non-volatile memory, processor, and battery, which can operate independently and adjust motion detection sensitivity through a graphical user interface, allowing for reduced energy consumption and flexible placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless intercom systems use Wi-Fi communication and hard wiring to a power source, then communication functionality is improved, but placement flexibility is reduced and energy consumption increases
Solution Approach 1:
The patent replaces the mechanical/electrical wiring system with a wireless power transmission system using electromagnetic fields. The doorbell unit communicates wirelessly with the base station, eliminating the need for hard-wired electrical connections while maintaining power supply and communication functionality. This substitution resolves the contradiction by enabling placement flexibility without compromising energy supply.
2Ease of operation
If multiple devices are installed throughout the home for wireless intercom functionality, then communication coverage is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent combines multiple functions (doorbell button, camera, microphone, speaker, motion sensor, and wireless communication module) into a single integrated doorbell unit. This consolidation eliminates the need for multiple separate devices throughout the home, simplifying both the system architecture and installation process while maintaining comprehensive communication and monitoring capabilities.
Solution Approach 2:
The doorbell unit is designed as a multi-functional device that performs doorbell signaling, video recording, audio communication, motion detection, and wireless communication simultaneously. This universal design allows a single device to replace multiple specialized devices, reducing system complexity and installation requirements while providing comprehensive home security functionality.
