Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a specific operation is controlled by the motion of one apparatus, then the operation can be started by user action, but the operation may be started unintentionally by imitators, reducing security
Solution Approach 1:
The patent combines motion detection from multiple apparatuses (first and second motion detection apparatuses) to verify that the same operation is detected by both devices within a predetermined time period. This merging of detection sources ensures that intentional operations by authorized users are recognized while preventing unauthorized activation by imitators, as the probability of multiple devices simultaneously detecting the same fraudulent gesture is extremely low.
Solution Approach 2:
The system implements a feedback mechanism where the first apparatus receives detection results from the second apparatus and compares them against its own detection data. This cross-verification feedback loop allows the system to confirm legitimate operations by checking consistency between multiple detection sources, thereby enhancing security while maintaining ease of operation for authorized users.
2Device complexity
If motion detection is used to control specific functions, then operation control is simplified, but unintended activation occurs reducing reliability
Solution Approach 1:
The patent merges the detection capabilities of multiple motion detection apparatuses into a unified verification system. By requiring that both the first and second apparatuses detect the same operation within a predetermined time window, the system maintains simple operation control for authorized users while significantly reducing unintended activation through the combined verification mechanism.

AI summary
An operation information measurement apparatus having a detection unit that detects information corresponding to a motion of a user includes: an operation information measurement unit that measures operation information of a user based on the information detected by the detection unit; a communication unit for performing near-field wireless communication with another apparatus; and a control unit that judges whether or not a first operation based on the detection information detected at a certain time by the detection unit of the operation information measurement apparatus matches a second operation based on detection information of a detection unit received from the other apparatus via the communication unit in a period from the certain time to a time when an amount of time corresponding to a first threshold elapses, and based on the result of that judgment, the control unit determines whether or not to output a command signal to the control unit.
