QR Measurement Scale Using Image Data Without Field Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement systems for outdoor environments, such as those used in hydrology, construction, and leisure activities, require power and infrastructure, are costly and lack energy efficiency, making them impractical in areas with limited communication and power infrastructure.
Innovation Solution
A QR code-based measurement apparatus with a fixed background pattern overlaid by a foreground sliding mask, where the relative position of the mask shifts based on measured data, allowing for passive, energy-efficient measurement and data encoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If traditional measurement systems are used in outdoor environments, then measurement functionality is achieved, but power consumption and infrastructure requirements increase
Solution Approach 1:
The patent replaces traditional electronic measurement systems with a光学-based measurement apparatus that uses optical patterns (QR codes) and image processing to obtain measurement data, eliminating the need for power-consuming electronic sensors and processing units in the field device
Solution Approach 2:
The patent creates a visual copy of measurement information through QR code patterns that encode measurement data in a machine-readable format, allowing measurement data to be captured and transmitted without active electronic components at the measurement site
2Measurement precision
If traditional measurement systems are deployed, then accurate measurement is achieved, but cost and infrastructure requirements increase
Solution Approach 1:
The patent encodes measurement data into QR code patterns that can be read by standard mobile device cameras, replacing complex electronic measurement and communication infrastructure with simple optical encoding that uses existing ubiquitous devices
Solution Approach 2:
The measurement apparatus uses standard QR code technology that can be read by any smartphone or mobile device with a camera, making the system universally compatible and eliminating the need for specialized reading equipment or infrastructure
3Use of energy by moving object
If passive measurement without power is implemented, then energy efficiency is improved, but measurement data generation capability is limited
Solution Approach 1:
The patent pre-encodes multiple measurement values into the QR code pattern structure, allowing the passive apparatus to provide measurement data for multiple conditions without requiring active processing or power consumption at the time of measurement
Solution Approach 2:
The patent introduces an intermediate processing step where mobile device software captures the QR code image and performs the measurement data extraction and interpretation, separating the passive data storage function from the active data processing function
