Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies, such as BLE, face challenges in rapidly acquiring and transmitting data due to large data transmission intervals, leading to delayed interaction between devices, especially in scenarios like smart wristbands and mobile phones where immediate data viewing is needed.
Innovation Solution
A method involving user equipment that determines the information to be sent and corresponding frequencies based on a preset rule, controlling capacitance values to change at these frequencies for out-of-band information interaction, allowing devices in contact with the same human body to exchange data more conveniently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a smaller connection interval is set to enable higher data acquisition speed, then data transmission frequency increases, but the set command cannot be sent to peer device until the next transmission opportunity, resulting in interaction delay
Solution Approach 1:
The patent introduces a capacitance change mechanism as an intermediary communication channel between devices. Instead of relying solely on the constrained wireless transmission intervals, the system uses capacitance changes (detected through touch or proximity) as a mediator to trigger and initiate data transmission commands, bypassing the waiting time for scheduled transmission opportunities.
Solution Approach 2:
The system performs preliminary actions by pre-establishing the communication link and preparing data buffers before the actual transmission opportunity arises. The capacitance detection mechanism is continuously monitored and ready to immediately trigger pre-prepared data transmission when activated, eliminating the delay between command generation and execution.
2Use of energy by moving object
If traditional wireless transmission intervals are used, then power consumption is reduced through lower transmission frequency, but data acquisition and interaction speed are limited
Solution Approach 1:
The patent implements periodic capacitance sampling and change detection at optimized intervals that balance power consumption with responsiveness. The system periodically checks for capacitance changes (which indicate user interaction) and only activates full data transmission when such changes are detected, rather than continuously transmitting or polling at high frequency.
Solution Approach 2:
The system uses the user's own body capacitance as the trigger mechanism for data transmission. The human body naturally provides the capacitance change signal when interacting with the device (touching or bringing close), eliminating the need for separate power-intensive command signaling mechanisms.
