Solution Overview
Problem
Consumers face the challenge of integrating Internet of Things (IoT) functionality into existing appliances without the need to replace functioning devices, as new IoT-enabled appliances can be costly and wasteful.
Innovation Solution
A system incorporating a micro-electro-mechanical system (MEMS) sensor and a computerized controller that communicates with the appliance to detect operating conditions, such as vibration and runtime, allowing for notifications to user devices without requiring the appliance to be replaced, using a cost-effective add-on component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new IoT-enabled appliances are purchased, then IoT functionality is achieved, but cost and waste increase
Solution Approach 1:
The system segments IoT functionality into a separate, independent module (the sensor device with accelerometer, processor, and transmitter) that can be attached to existing appliances. This allows the IoT capability to be added without replacing the entire appliance, thus avoiding waste while achieving adaptability.
Solution Approach 2:
The sensor device is designed as a universal add-on that can be attached to multiple types of appliances (washing machines, dryers, etc.) through adhesive mounting. The device monitors various operating conditions including vibration, runtime, and operational states, providing multi-functional monitoring capabilities across different appliance types.
2Adaptability or versatility
If new IoT-enabled appliances are purchased, then IoT functionality is achieved, but cost increases
Solution Approach 1:
By segmenting the IoT functionality into a separate low-cost sensor device rather than integrating it into expensive new appliances, the system achieves significant cost reduction. The sensor device uses affordable components (accelerometer, basic processor, transmitter) that can be mass-produced at low cost.
Solution Approach 2:
The sensor device acts as an intermediary between existing appliances and the IoT network. It bridges the gap by adding communication and monitoring capabilities to legacy appliances without requiring replacement of the expensive appliance itself, thus reducing overall system cost.
3Measurement precision
If a MEMS sensor is physically attached to the appliance, then operational detection is enabled, but device complexity increases
Solution Approach 1:
The sensor device is designed to be self-contained and self-configuring. It autonomously monitors appliance operations, processes sensor data locally using its integrated processor, and automatically transmits information to remote devices. This self-service capability reduces the complexity burden on the user and simplifies installation.
Solution Approach 2:
The system replaces complex mechanical monitoring mechanisms that would be required to built into appliances with electronic sensor-based detection. The accelerometer and other electronic sensors provide precise measurement of vibration, position, and operational states without requiring mechanical linkages or complex mechanical sensing systems.
