BLE Trajectory Control for Button-Free Device Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth Low Energy (BLE) devices require cumbersome operations such as button presses or display interactions for pairing and control, leading to potential errors and increased costs, which affect user experience and product aesthetics.
Innovation Solution
A wireless control method using Bluetooth direction positioning technology to track the relative movement trajectory between BLE devices, allowing for accurate control functions without manual input, by receiving positioning packets and determining corresponding control instructions based on predetermined mapping relationships.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display module or button is used to trigger BLE device operations, then device can perform pairing and control functions, but operation becomes cumbersome and error rate increases
Solution Approach 1:
The patent replaces mechanical interaction (buttons, display touches) with wireless mechanical-free interaction through trajectory-based control. The control terminal detects trajectories of controlled devices in space and translates them into control instructions, eliminating the need for physical buttons or display interactions while improving both ease of operation and control accuracy.
Solution Approach 2:
The patent introduces trajectory information as an intermediary between the controlled device and control terminal. Instead of direct button presses or display interactions, the system uses trajectory data (position, speed, acceleration) as a mediator to transmit control intent, enabling more reliable and intuitive control.
2Ease of operation
If display module or button is added to BLE device, then control functions can be triggered, but product cost increases
Solution Approach 1:
The patent extracts the control triggering function from physical components (buttons, display modules) and relocates it to the wireless communication and trajectory processing system. The controlled device no longer needs these expensive components because control operations are initiated through trajectory-based wireless interaction.
Solution Approach 2:
The patent replaces expensive, complex hardware components (display modules, buttons) with simpler, cheaper wireless communication capabilities. The trajectory-based control mechanism uses existing wireless hardware to achieve control functions that previously required expensive add-on components.
3Adaptability or versatility
If multiple BLE devices are controlled, then system functionality increases, but device distinction becomes difficult causing false control
Solution Approach 1:
The patent uses trajectory characteristics (position, movement pattern, speed) as distinctive identifiers for different devices, analogous to using color to distinguish objects. Each device's unique trajectory signature allows the control terminal to accurately identify and differentiate between multiple controlled devices, preventing false control.
Solution Approach 2:
The patent segments the control space by tracking individual device trajectories separately. Each controlled device operates in its own trajectory space, and the control terminal processes trajectory information for each device independently, enabling precise device identification and control even when multiple devices are present.

AI summary
A wireless control method, a device, a BLE apparatus, a chip, and a storage medium. The BLE apparatus as a control end communicates with at least one other BLE apparatus via a Bluetooth link. The method comprises: S01, receiving a positioning packet sent by the at least one other BLE apparatus at a preset time interval; S02, obtaining, in accordance with the received positioning packet and by using a Bluetooth orientation technique, a first relative movement path of the at least one other BLE apparatus with respect to the BLE apparatus; S03, determining, according to a pre-determined mapping relationship, a control function corresponding to the first relative movement path; and S04, sending, in accordance with the control instruction to the at least one other BLE apparatus to perform the control function.
