Bezel-Free Biometric Relief Print Generator via Integrated Electrode Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric relief print generator devices, such as fingerprint recognition systems, are often bulky and difficult to use due to the need for a contact electrode, which can be challenging for young children and individuals with rheumatic diseases to operate effectively.
Innovation Solution
Incorporating multiple electrodes in an electrode layer with different voltage characteristics allows for the creation of an electrical circuit without a contact electrode, enabling the device to function by having the biometric object contact a scanning surface, thereby eliminating the need for a bezel and enhancing user-friendliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contact electrode is used to complete the electrical connection, then the device can function properly, but the device becomes heavy and bulky
Solution Approach 1:
The patent combines multiple electrodes into a single integrated electrode layer. The transparent electrode panel with scribed lines creates multiple functional electrodes (first electrode, second electrode, third electrode) within one unified structure, eliminating the need for separate contact electrodes and bezels. This merging reduces device weight and bulk while maintaining the electrical connection function.
2Reliability
If a contact electrode is used to complete the electrical connection, then the device can function properly, but the device structure becomes complex
Solution Approach 1:
The patent merges multiple electrode functions into a single electrode layer with scribed lines. Instead of having separate contact electrodes and bezels, the invention integrates everything into one transparent electrode panel that serves multiple functions: electrical connection, structural support, and optical transparency. This significantly simplifies the overall device structure.
Solution Approach 2:
The transparent electrode panel performs multiple functions simultaneously: it provides electrical connection through scribed lines creating multiple electrodes, maintains structural integrity as a single panel, and allows optical transparency for the display. This multi-functionality reduces the number of separate components needed in the device.
3Reliability
If a contact electrode is used, then electrical connection can be established, but it becomes difficult for users to contact both surface and electrode simultaneously
Solution Approach 1:
The patent merges the contact surface and electrode into the same transparent electrode panel. The scribed lines create electrodes that are integrated into the surface itself, allowing users to make contact with the electrode by simply touching the surface area, rather than needing to precisely contact separate electrode regions at the perimeter. This dramatically improves ease of operation.
4Reliability
If a bezel with contact electrode is used, then electrical connection is achieved, but the device becomes less portable
Solution Approach 1:
The patent merges the electrode function into the main body of the device through the transparent electrode panel, eliminating the need for protruding bezels. This integration reduces the overall device volume and makes the device more portable while maintaining reliable electrical connection through the scribed electrode lines.

AI summary
One or more systems and/or methods are disclosed for building a relief print generator with no bezel. An electrode layer having more than one electrode can be used in an electrode-based, electro-luminescence component of the relief print generator. The respective electrodes may be connected to power sources with different voltage phases. An electrical circuit can be created between a biometric object and more than one electrode in the electrode layer when the biometric object contacts a surface of the generator. The electro-luminescent component can be activated by electrical charge and emit light indicative of a relief print of the biometric object. A contact electrode outside the electrode layer may not be used, which may allow for the removal of a bezel from an example device.
