Allochroic Code Transitional Cells for Visual Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information codes that change color in response to ambient temperature can be visually jarring for users, making it uncomfortable to perceive changes in physical quantities.
Innovation Solution
A mechanically readable code comprising a first area with recorded information and a second area featuring allochroic cells that change color based on physical quantities, with transitional color cells to minimize visual impact, using inorganic or organic materials like leuco dyes and developers for color change, and strategically placing these cells in a non-use region to avoid affecting the information area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ink for printing cells changes color depending on a predetermined condition (temperature), then the code can easily perceive ambient environment changes visually, but the user feels odd when looking at the code
Solution Approach 1:
The patent applies color change technology through allochroic cells that change color in response to physical quantity changes (temperature, humidity). The key innovation is using transitional color cells that display intermediate colors during the transition process, making the color change gradual and natural rather than abrupt. This resolves the contradiction by enabling clear physical quantity perception through color changes while minimizing user discomfort through smooth transitional colors.
2Reliability
If multiple diversified cells are used to record data and error-correcting codes, then the code can store information reliably, but the code area requires more space
Solution Approach 1:
The patent makes the code cells multi-functional by enabling them to serve both as data recording elements and as physical quantity sensing elements. The allochroic cells simultaneously encode information and respond to environmental conditions, while transitional color cells provide both error correction capability and visual transition indicators. This consolidation reduces the overall code area while maintaining reliability through the dual functionality of each cell.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The code allows users to perceive changes in physical quantities without feeling odd, as the color change of allochroic cells is subtle and integrated into the overall design, enhancing user experience and information processing systems.
Implementation Method 1
a second area comprising multiple second unit cells including an allochroic cell that changes in color depending on a physical quantity
Implementation Method 2
The multiple first unit cells include transitional color cells having any transitional color in the process of color change of the allochroic cell
