Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face challenges in accurately determining whether a user is holding the correct portable device associated with them, particularly when using radio wave signals with fixed output intensities, which can lead to incorrect authentication and management of health statuses and operational processes.
Innovation Solution
An information processing apparatus that includes an authenticating unit, a transmitting unit, and a determining unit, which transmits action instructing signals at varying radio wave output intensities to a portable device, detecting changes in the device's status and determining if they match the instructed actions, thereby verifying the user's possession of the correct device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radio wave output intensity is fixed, then the authentication process is simple, but the accuracy of determining whether the user is holding the correct portable device decreases
Solution Approach 1:
The patent applies dynamics by making the radio wave output intensity variable rather than fixed. The transmitting unit selectively transmits action instructing signals at multiple different radio wave output intensities, allowing the system to adapt to different detection needs and improve measurement precision without requiring a completely complex new system
Solution Approach 2:
The patent changes the parameter of radio wave output intensity from a fixed value to multiple selectable values. By transmitting signals at different intensities and comparing the detected status changes, the system achieves higher accuracy in determining device possession while managing complexity through parameter variation
2Area of stationary object
If radio wave output intensity is increased, then the detection range is improved, but the energy consumption increases
Solution Approach 1:
The patent uses partial action by transmitting radio wave signals at multiple intensities rather than always using maximum intensity. The transmitting unit selectively chooses appropriate intensities based on detection needs, achieving sufficient detection range while avoiding excessive energy consumption that would result from continuously using high power signals

Implementation Method 1
The transmitting unit transmits an action instructing signal for issuing an instruction to perform an action to a portable device that is associated with the user at plural radio wave output intensities selectively, via a radio communication line
Implementation Method 2
The detecting unit detects, for at least one of the plural radio wave output intensities, a change of a status of the portable device that is being held by the user
