Solution Overview
Problem
Wearable devices consume excessive resources and have prolonged recovery times due to continuous data transmission and sensor reactivation, especially in static states, degrading user experience.
Innovation Solution
A wearable device with a motion sensor and processor dynamically adjusts data transmission based on motion thresholds, transmitting data only when active and maintaining sensor operation, reducing resource consumption and eliminating restart requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wearable device continuously transmits sensing data to the computing device, then the computing device can perform data calculations, but the transmission resources and computing resources of the wearable device are consumed, reducing battery standby time
Solution Approach 1:
The patent implements dynamic adjustment of data transmission based on motion state detection. The processor determines whether to transmit data by comparing motion sensing values against thresholds, switching between active transmission mode (when motion exceeds threshold) and inactive mode (when motion is below threshold). This dynamic approach resolves the contradiction by making transmission behavior adaptive rather than static, ensuring data reliability when needed while conserving energy during static periods.
Solution Approach 2:
The patent changes the transmission parameter (data transmission state) based on the motion parameter. By monitoring motion sensing values and comparing them to thresholds, the system adjusts the transmission parameter between two states: transmitting data when motion exceeds the threshold and not transmitting when it doesn't. This parameter change strategy resolves the energy-reliability contradiction by linking transmission behavior to actual motion conditions.
2Use of energy by moving object
If the wearable device turns off the sensor to save energy, then energy consumption is reduced, but the device requires restart and re-pairing, increasing recovery time
Solution Approach 1:
Instead of completely turning off the sensor (excessive action), the patent applies partial action by selectively transmitting data based on motion thresholds. The sensor remains active and continuously monitors motion, but data transmission occurs only when necessary (when motion exceeds threshold). This partial transmission approach resolves the contradiction by avoiding complete sensor shutdown, thus eliminating restart overhead while still reducing unnecessary transmission energy consumption.
Solution Approach 2:
The patent maintains continuous sensor operation and continuous monitoring capability, ensuring the sensor never fully shuts down. This continuity of useful action allows the device to immediately detect and respond to motion events without restart delays, resolving the time loss issue while still achieving energy savings through selective data transmission during static periods.
3Reliability
If the wearable device transmits data during static state with slight movements, then all motion data is captured, but transmission resources and computing resources are wasted, reducing standby time
Solution Approach 1:
The patent extracts only the necessary data transmission actions from the continuous transmission process. By comparing motion sensing values against thresholds, the system identifies and extracts only those moments when actual motion occurs (exceeding threshold), transmitting data only during these periods. This extraction approach resolves the contradiction by eliminating unnecessary transmissions during static states while preserving all meaningful motion data.
Solution Approach 2:
The patent implements feedback control by continuously monitoring motion sensing values and using this feedback to determine transmission decisions. The processor compares current motion values against thresholds and adjusts transmission behavior accordingly - transmitting when motion exceeds threshold and pausing when it doesn't. This feedback mechanism resolves the resource efficiency-reliability contradiction by ensuring data is transmitted only when actually needed, eliminating waste while maintaining accuracy.

AI summary
A wearable device, sensing data transmitting method, and non-transitory computer-readable recording medium thereof are provided. The wearable device determines whether a plurality of motion sensing values exceed a first threshold to determine whether the wearable device is in an active state or an inactive state. In response to the wearable device being in the active state, the wearable device transmits a sensing data to an external device through a wireless communication connection, the sensing data includes the motion sensing values. In response to the wearable device being in the inactive state, the wearable device does not transmit the sensing data to the external device and does not turn off a motion sensor of the wearable device.
