Wireless Communication Device Dynamic Advertising Interval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face a trade-off between power consumption and rapid re-connection in Bluetooth Low Energy (BLE) communication, where shortening the transmission cycle of advertising packets for re-connection increases power consumption, while lengthening it delays re-connection, making it difficult to set suitable settings for optimal performance.
Innovation Solution
The system maintains a short-distance wireless communication function even with the main power source off, using an advertising signal for network management, and automatically turns on the power for re-connection processing based on usage conditions, allowing for setting of connection control information such as advertising interval and re-connection time to optimize re-connection processing.

Engineering Contradiction Analysis
1Speed
If the transmission cycle of advertising packets is shortened to enable rapid re-connection, then the re-connection speed is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the advertising packet transmission cycle adjustable rather than fixed. The control unit dynamically changes the transmission cycle based on the operation state of the image capture apparatus - using a first cycle when the apparatus is off and a second cycle when it is on. This dynamic adjustment allows the system to optimize between re-connection speed and power consumption according to different operational contexts.
Solution Approach 2:
The patent changes the parameter of transmission cycle duration based on the operation state. When the image capture apparatus is in the off state, a first transmission cycle is used; when in the on state, a second transmission cycle is used. This parameter change enables the system to balance power consumption and re-connection speed by selecting appropriate transmission intervals for different operational phases.
2Use of energy by moving object
If the transmission cycle of advertising packets is lengthened to reduce power consumption, then power consumption is reduced, but re-connection time increases causing missed shutter clicks
Solution Approach 1:
The system dynamically adjusts the advertising packet transmission cycle based on operational needs. When the image capture apparatus is off and rapid re-connection is needed, a shorter first transmission cycle is used. When the apparatus is on and power conservation is prioritized, a longer second transmission cycle is applied. This dynamic switching prevents both excessive power consumption and missed shutter opportunities.
Solution Approach 2:
The transmission cycle parameter is changed according to the operation state of the image capture apparatus. The control unit selects between a first transmission cycle (shorter) and a second transmission cycle (longer) based on whether the apparatus is in the on or off state, thereby optimizing the balance between power consumption and re-connection timing.
3Adaptability or versatility
If it is difficult to set suitable transmission cycle settings to balance power consumption and re-connection speed, then system adaptability is reduced, but simpler control is achieved
Solution Approach 1:
The control unit automatically determines the appropriate transmission cycle based on the operation state of the image capture apparatus without requiring manual configuration. The system self-adjusts by selecting the first transmission cycle when the apparatus is off and the second cycle when it is on, eliminating the need for complex manual setting while maintaining high adaptability to different operational scenarios.
