Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an intelligent system to manage user devices, such as smartphones and smartwatches, as individuals often forget to take them when exiting or entering their homes, and there is a lack of a system to provide contextual notifications about the device's state, such as battery level, when entering or exiting a controlled environment.
Innovation Solution
A smart entry system that uses sensors like infrared, vibration, and camera sensors to detect individuals approaching a portal, connect with their user devices via Bluetooth or WiFi, and provide notifications about device presence, battery level, and other contextual information, while recognizing registered users and guests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart entry system with multiple sensors and wireless connectivity is implemented, then device management capability and user notification capability are improved, but device complexity increases
Solution Approach 1:
The smart entry system is divided into separate functional modules: detector module (with infrared, vibration, and camera sensors), transceiver module (for wireless communication), user interface module (for notifications), and processor module. Each module performs a specific function, making the complex system manageable and maintainable while achieving versatile device management capabilities.
Solution Approach 2:
The system integrates multiple sensor types (infrared, vibration, camera) and communication protocols (Bluetooth, WiFi) into a single multi-functional platform that can detect various conditions, communicate with different user devices, and provide comprehensive device management and notifications through a unified interface.
2Measurement precision
If multiple sensors are used to detect individuals and their devices, then detection accuracy and user identification capability are improved, but device complexity increases
Solution Approach 1:
The system combines infrared sensors, vibration sensors, and camera sensors into an integrated detection system that works together to identify individuals and their devices. The processor correlates data from all sensor types to achieve accurate detection and identification, reducing the need for each sensor to independently perform complex functions.
Solution Approach 2:
The processor acts as an intermediary that receives and correlates data from multiple sensor types, translating raw sensor signals into meaningful detection results. This mediator component simplifies the complexity by centralizing the interpretation logic rather than requiring each sensor to independently process complex data.
3Loss of information
If wireless connection attempts are made with user devices, then device presence detection and contextual information retrieval are improved, but energy consumption increases
Solution Approach 1:
The transceiver attempts wireless connections with user devices at periodic intervals rather than continuously, checking for device presence and retrieving contextual information only when needed. This periodic approach maintains effective device detection capability while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The system leverages the user device's own wireless communication capabilities and existing data (such as battery level information already stored on the device) to provide contextual information, rather than requiring constant active querying. The device essentially serves itself by maintaining its own state information that the entry system can retrieve when connected.
