Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer methods between electronic devices require multiple user interactions, which can be cumbersome, especially on devices with small interfaces, and existing contact-based methods do not allow users to set the direction of data flow without user interface interaction.
Innovation Solution

Engineering Contradiction Analysis
1Ease of operation
If contact-based methods are used to initiate data transfer, then the number of user interactions is reduced, but physical contact between devices is required
Solution Approach 1:
The patent replaces the mechanical contact-based initiation system with a motion detection system using accelerometers and gyroscopes. Instead of requiring physical tapping or contact between devices, the system detects movement patterns through inertial sensors, substituting mechanical interaction with sensor-based motion recognition. This allows data transfer initiation through deliberate device movement without physical contact.
Solution Approach 2:
The patent changes the initiation parameter from physical contact state to motion vector characteristics. By analyzing movement magnitude, direction, and duration through sensor data, the system transforms the initiation condition into a parameter-based detection mechanism. This allows flexible interpretation of user intent through various movement patterns rather than requiring a specific physical contact action.
2Ease of operation
If automated data transfer is implemented without user interface interaction, then ease of operation is improved, but the ability to set data flow direction is lost
Solution Approach 1:
The patent enables the system to automatically determine data flow direction by analyzing the relative motion of devices. The motion detection algorithm identifies which device is moving toward the other and uses this information to autonomously establish the data transfer direction. This self-service mechanism eliminates the need for user interface interaction while preserving directional control through intelligent motion interpretation.
Solution Approach 2:
The system uses feedback from motion sensors to dynamically adjust and determine data flow direction. By continuously monitoring acceleration and orientation data, the system receives real-time feedback about device movement and uses this information to automatically configure the appropriate data transfer direction, maintaining control without user intervention.
3Extent of automation
If multiple user actions are required for data transfer, then data flow direction can be controlled, but the complexity of the transfer process increases
Solution Approach 1:
The patent performs preliminary action by pre-configuring motion detection thresholds and transfer parameters before data transfer is needed. The system anticipates user intent through motion patterns and pre-establishes the data flow direction based on detected movement, eliminating the need for subsequent user actions to configure transfer settings. This reduces the apparent complexity by having the system ready ahead of time.
Solution Approach 2:
The patent merges multiple functions into the motion detection process. The same motion analysis that initiates data transfer also determines data flow direction, selects transfer parameters, and triggers the transfer operation. By combining these functions into a single integrated motion-based control mechanism, the system reduces the number of separate steps and user actions required while maintaining comprehensive control.

AI summary
A method for information transfer comprising determining a signed magnitude value of a first and second movement vectors corresponding to movements of the devices. Each value is assigned a positive or a negative sign based on direction of the movement with respect to direction of gravity. Real number values of the signed magnitude values are compared on fulfillment of one or more conditions. A position of the first device is defined as an above position relative to the second device if the real number value corresponding to the first movement vector is found to be smaller than the signed magnitude value corresponding to the second movement vector, the signed magnitude value being assigned a negative sign when the direction of the movement is substantially along the direction of gravity and assigned a positive sign when the movement is opposite to the direction of gravity.
