Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing systems face challenges in ensuring that rendering materials, such as printing fluids in cartridges, are adequately conditioned to maintain image quality, as components can settle over time, leading to inconsistent pigment distribution and reduced image quality.
Innovation Solution
A system and method using a passive transceiver with an RFID tag and an embedded antenna in the storage structure, which generates a response signal when exposed to an electromagnetic field, allowing the printing system to determine the conditioning parameters like duration, direction, and speed of shaking, ensuring the fluid is adequately mixed before use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a passive transceiver with RFID tag is used to monitor conditioning, then measurement precision of conditioning parameters is improved, but device complexity increases
Solution Approach 1:
The passive transceiver in the storage structure automatically detects and reports conditioning parameters (shaking duration, intensity, orientation) without requiring external active components in the storage structure. The RFID tag passively responds to electromagnetic fields, enabling self-monitoring of conditioning status.
Solution Approach 2:
The patent replaces complex mechanical sensing systems with electromagnetic field-based RFID detection. Instead of using mechanical sensors to detect shaking and orientation, the system uses changes in electromagnetic field interaction caused by the physical movement and orientation of the passive transceiver antenna.
2Ease of operation
If user manually conditions rendering material, then ease of operation is improved, but reliability of image quality deteriorates
Solution Approach 1:
The system provides automatic feedback to the user about whether the rendering material has been adequately conditioned. The processor analyzes data from the passive transceiver and communicates conditioning status, allowing users to know when sufficient shaking has occurred without requiring expert judgment or trial-and-error.
Solution Approach 2:
The system performs preliminary monitoring of conditioning parameters before the rendering process begins. By detecting shaking duration, intensity, and orientation in advance, the system ensures proper mixing occurs before the material is used, preventing quality issues during actual rendering.
3Manufacturing precision
If auxiliary shaking units are used to ensure homogeneous mixing, then manufacturing precision of fluid distribution is improved, but device complexity and cost increase
Solution Approach 1:
The system performs preliminary monitoring of conditioning parameters before rendering begins. By detecting shaking duration, intensity, and orientation in advance, the system ensures proper mixing occurs before the material is used, preventing quality issues during actual rendering.
Solution Approach 2:
The passive transceiver automatically monitors and reports conditioning status without requiring external active components in the storage structure. The RFID tag passively responds to electromagnetic fields, enabling self-monitoring of conditioning status and eliminating the need for complex active sensing systems.
