Portable Terminal Acceleration Sensor for Data Transfer Initiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable terminals require complex operations to initiate data transfer via short-range wireless communication, making it difficult for users to successfully perform data transfer, especially when the terminals are in motion or experiencing environmental changes like vibration and light variations, which are common in portable devices.
Innovation Solution
A portable terminal equipped with a sensor to detect changes in posture or physical movement, allowing users to select data for transfer through an interface, and automatically initiating short-range wireless communication, such as infrared, when specific movement thresholds are met, accompanied by alarm sounds and vibrations to confirm data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If short-range wireless communication is initiated by detecting change in light-receiving amount and vibration, then communication can start automatically, but communication is frequently initiated at unnecessary timings
Solution Approach 1:
The patent changes the detection parameter from light-receiving amount and vibration to acceleration magnitude. By setting a specific threshold value for acceleration magnitude, the system distinguishes between normal portable movements and intentional communication initiation actions, thereby reducing false triggers while maintaining automatic initiation capability.
Solution Approach 2:
The patent uses acceleration detection as a proxy for user intent rather than directly detecting communication readiness. The acceleration signal serves as a copied indicator of the user's intention to initiate communication, allowing indirect but more reliable detection of the desired state.
2Ease of operation
If complicated operations are required to start data transfer function, then precise control is achieved, but users unable to complete operations or operate wrongly
Solution Approach 1:
The system performs data transfer automatically upon detecting acceleration above the threshold, without requiring the user to complete multiple manual steps. The user simply needs to select the data and the system handles the communication initiation itself, making the operation self-executing and greatly simplifying the user's task while ensuring reliable completion.
Solution Approach 2:
The system prepares the communication function in advance by continuously monitoring acceleration. When the threshold is exceeded, the pre-prepared communication routine executes immediately, eliminating the need for users to perform complex sequences of operations during the moment of data transfer initiation.
3Ease of operation
If acceleration detection threshold is set low, then easy initiation is achieved, but initiation occurs during normal portable movements
Solution Approach 1:
The patent establishes an appropriate threshold value for acceleration magnitude that distinguishes between normal portable movements and intentional communication initiation. This threshold parameter is carefully selected to balance ease of initiation with prevention of false triggers, resolving the contradiction between sensitivity and reliability.
