Solution Overview
Problem
Existing digital caregiving platforms face challenges with user interfaces that are difficult for elderly users due to small icons and quiet audio, inability to perform health checks without in-person visits, and inadequate handling of real-time responses, particularly with HTTP-based communication protocols that are bandwidth-intensive and unsuitable for multimedia data transmission.
Innovation Solution
A digital assistance system using a finger touch pad with sensors for health measurements and a MQTT communication protocol to transmit multimedia data in ASCII format, enabling scalable and bidirectional communication between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If HTTP-based communication protocol is used for digital caregiving platforms, then wide compatibility is achieved, but bandwidth efficiency deteriorates and real-time response capability is insufficient
Solution Approach 1:
The patent changes the communication protocol from HTTP to MQTT, fundamentally altering the transmission parameters. MQTT uses publish-subscribe model with persistent connections and smaller packet overhead, achieving up to 90% bandwidth reduction compared to HTTP while maintaining real-time responsiveness for caregiving applications
Solution Approach 2:
The patent introduces an MQTT broker as an intermediary component that manages message routing between caregiving devices. The broker enables efficient many-to-many communication patterns, allowing multiple sensors and caregivers to exchange data through a centralized coordination point, improving overall system bandwidth efficiency
2Adaptability or versatility
If digital caregiving platforms use standard computing devices, then device availability is improved, but health measurement capability deteriorates
Solution Approach 1:
The patent transforms standard computing devices into multi-functional caregiving platforms by integrating health sensors, GPS tracking, and communication modules. The same device that runs the caregiving application also performs health measurements, eliminating the need for separate measurement equipment while maintaining device availability
Solution Approach 2:
The patent merges health measurement functions with the caregiving platform by integrating sensors (accelerometers, heart rate monitors, temperature sensors) directly into the computing device. This combination allows the device to simultaneously provide user interface capabilities and health monitoring, solving both availability and measurement capability requirements
3Quantity of substance
If graphical user interfaces with small icons are used in digital caregiving platforms, then information density is improved, but ease of operation for elderly users deteriorates
Solution Approach 1:
The patent implements a dynamic user interface that adapts to user needs and context. The interface can switch between detailed views for information density and simplified views with larger elements for ease of operation. Audio feedback and voice control options provide alternative interaction modes that accommodate elderly users with varying dexterity and vision capabilities
Solution Approach 2:
The patent introduces voice recognition and audio output as intermediary interfaces between the user and the system. Voice commands allow elderly users to interact with the platform without needing to manually manipulate small icons, while text-to-speech conversion provides audio feedback that complements visual information, making the interface more accessible
