Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile dimensioning devices face challenges in varying lighting conditions, reflective or camouflaged objects, and motion artifacts, leading to inaccurate measurements and user frustration in interpreting user intent.
Innovation Solution
A user-guided mode is introduced, utilizing a combination of cameras like stereo, time-of-flight, and structured light cameras, with interactive interfaces such as virtual measuring instruments and voice commands to provide real-time feedback and correction, enhancing user interaction and system accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated dimensioning is used without user guidance, then productivity is improved, but measurement precision deteriorates in challenging environments
Solution Approach 1:
The system implements a feedback mechanism where the automated dimensioning system first provides an initial measurement, then the user can review and correct the measurement if needed. This feedback loop allows the system to maintain high productivity through automated initial dimensioning while ensuring measurement precision through user verification and correction capabilities.
2Ease of operation
If full automated dimensioning is implemented, then ease of operation is improved, but reliability deteriorates due to inability to interpret user intent
Solution Approach 1:
The system introduces an intermediary step where the automated system proposes a measurement interpretation, and the user confirms or corrects it. This intermediary mechanism bridges the gap between automated operation and reliable intent interpretation, allowing the system to operate simply while maintaining reliability through user validation.
3Measurement precision
If user guidance interface is added, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system uses a virtual copy of the physical object displayed on a screen, allowing users to interact with and correct measurements in a digital representation rather than requiring complex physical adjustment mechanisms. This virtual copying approach enables precise measurement correction without adding significant physical device complexity.
4Measurement precision
If real-time correction capability is provided, then measurement precision is improved, but loss of time increases due to user intervention
Solution Approach 1:
The system implements partial user intervention by allowing corrections only when needed, rather than requiring full user review of every measurement. Users can quickly confirm accurate measurements with minimal action, while having the option to correct only those measurements that require attention, thus reducing overall time loss while maintaining precision.
