Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equipment control devices face issues such as unnecessary power consumption, inappropriate alarm triggering, and delayed equipment control due to reliance on static positional information or user posture, leading to inefficiencies and inaccuracies in managing equipment states based on user presence and activity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If equipment control is based on simple presence detection (e.g., person sensor output), then equipment can be controlled to ON state when user is present, but unnecessary power consumption occurs when persons passing by are detected without actual usage intent
Solution Approach 1:
The patent transitions from static presence detection to dynamic trajectory analysis. By continuously tracking the user's movement path over time and analyzing whether the trajectory approaches the equipment, the system dynamically determines usage intent. This resolves the contradiction by enabling accurate control decisions (improving productivity) while avoiding false positives from casual passersby (reducing unnecessary power consumption).
Solution Approach 2:
The system performs preliminary trajectory analysis before triggering equipment activation. By monitoring and storing user movement patterns in advance and evaluating whether the trajectory indicates genuine approach intent, the system prepares control decisions based on predicted usage behavior. This preliminary action ensures equipment is activated only when truly needed, improving control accuracy while preventing wasteful power consumption from premature or incorrect activation.
2Reliability
If alarm control is based on simple proximity detection of radio tags, then alarm can be triggered when user approaches restricted area, but inappropriate alarm triggering occurs for persons merely passing by the boundary
Solution Approach 1:
The patent applies dynamic trajectory analysis to alarm control by evaluating the user's movement path rather than static position. The system analyzes whether the trajectory indicates intentional approach to the restricted area or merely incidental proximity. This dynamic evaluation improves alarm control reliability by distinguishing genuine intrusions from casual passings, while reducing inappropriate alarm outputs that cause harm or disturbance.
3Speed
If equipment control is based on static positional information, then control decisions can be made quickly, but accuracy in detecting user presence and activity is reduced
Solution Approach 1:
The system performs preliminary trajectory tracking and pattern recognition before making control decisions. By continuously collecting and analyzing movement data in advance, the system builds an accurate understanding of user presence and intent. This preliminary action enables quick control decisions with high accuracy, as the trajectory analysis framework is already established and can rapidly evaluate new position data against stored patterns.
Solution Approach 2:
The patent implements dynamic trajectory analysis that continuously updates user position and movement patterns. Rather than relying on static snapshots, the system processes sequential position data to build an evolving picture of user behavior. This dynamic approach maintains measurement precision by capturing actual movement patterns while enabling speed through efficient real-time trajectory evaluation and pattern matching.
