Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Active scanning systems for 3D modeling are more accurate but require expensive equipment and high energy consumption, posing a challenge for remote locations where battery power is limited.
Innovation Solution
Utilizing a person's gaze to initiate and control active scanning of regions of interest (ROI), allowing more efficient data aggregation and reducing energy consumption by activating scanning only when the user's gaze is fixed on the ROI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If active scanning is used to achieve high accuracy 3D modeling, then measurement precision is improved, but use of energy by moving object deteriorates
Solution Approach 1:
The patent applies dynamics by making the active scanning system adaptable through gaze tracking. The scanning system transitions from static continuous operation to dynamic conditional operation, activating only when gaze fixation is detected. This resolves the contradiction by enabling high-precision scanning of relevant areas while reducing overall energy consumption through intelligent activation control.
Solution Approach 2:
The patent applies local quality by directing active scanning resources specifically to regions of interest identified through gaze tracking. Instead of uniformly scanning the entire environment, the system concentrates high-precision scanning only on locally relevant areas where the user is looking, thereby improving measurement precision for critical areas while reducing total energy consumption.
2Manufacturing precision
If active scanning system is deployed for high accuracy modeling, then manufacturing precision is improved, but device complexity deteriorates
Solution Approach 1:
The patent applies universality by integrating multiple functions into a unified system. The gaze tracking mechanism serves dual purposes: it identifies regions of interest for targeted scanning while also controlling the activation timing of the active scanning system. This multi-functionality reduces device complexity by consolidating control logic rather than requiring separate independent systems.
Solution Approach 2:
The patent applies the intermediary principle by introducing gaze tracking as a mediator between the user and the active scanning system. The gaze tracking system acts as an intermediary that translates user attention into scanning commands, enabling precise control of the scanning system without requiring direct complex user input or continuous operation, thereby reducing overall system complexity.
3Productivity
If continuous active scanning is performed to capture all data, then productivity is improved, but use of energy by moving object deteriorates
Solution Approach 1:
The patent applies periodic action by replacing continuous scanning with intermittent scanning triggered by gaze fixation events. The active scanning system operates periodically rather than continuously, activating only during periods when the user is fixating on specific areas. This maintains productivity by capturing data at critical moments while dramatically reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The patent applies preliminary action by using gaze tracking to identify and pre-select regions of interest before initiating active scanning. The system preliminarily determines which areas require high-precision scanning based on user gaze patterns, then activates scanning only for those pre-identified regions. This approach maintains data collection efficiency by focusing on relevant areas while reducing energy consumption through targeted rather than comprehensive scanning.
