Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a credit card maintains a compact form factor (85.60mm×53.98mm×0.8mm), then it can fit in a user's wallet or pocket, but it becomes difficult for visually impaired users to read printed information and limits the ability to include electronic features
Solution Approach 1:
The patent replaces traditional mechanical printing systems with an OLED electronic display system. The OLED display can dynamically generate and enlarge text, replacing static printed information that is difficult for visually impaired users to read. This substitution enables the card to provide accessible information without increasing its physical dimensions.
Solution Approach 2:
The patent changes the parameter of information presentation from fixed printed text to dynamically adjustable electronic display. The OLED display can modify text size, contrast, and content based on user needs, allowing visually impaired users to access information in formats suitable for their requirements while maintaining the card's compact form factor.
2Ease of operation
If sensitive data is printed on the face of the card, then it is easily readable by users, but it becomes visible to onlookers who may obtain copies through pictures
Solution Approach 1:
The patent implements dynamic control over data visibility through the OLED display. Sensitive information can be displayed only when needed for user interaction, and the display can be controlled to show different information at different times. This dynamic approach replaces static printed data that is continuously visible, thereby reducing the risk of unauthorized copying while maintaining user accessibility.
Solution Approach 2:
The OLED display acts as an intermediary between the card's data storage and the user. Instead of directly printing sensitive data on the card surface, the information is displayed through the OLED only when required for authentication or transaction purposes, providing controlled access that protects against unauthorized viewing and copying.
3Reliability
If a skimming device is placed on or in an ATM card reader, then it can obtain copies of sensitive data encoded on the magnetic stripe, but it does not impede access to the card reader
Solution Approach 1:
The patent replaces the magnetic stripe encoding system with an OLED-based visual authentication system. This substitution eliminates the magnetic stripe that skimming devices target, thereby removing the vulnerability to skimming attacks. The OLED display provides visual confirmation of card authenticity without relying on magnetic stripe data that can be copied by skimmers.
4Ease of operation
If electronic features are included in a purchasing instrument, then usability and security are enhanced, but the form factor cannot be maintained without a large power supply
Solution Approach 1:
The patent utilizes the specific parameters of OLED technology, particularly its low power consumption characteristics. OLED displays consume significantly less power compared to traditional display technologies, enabling the integration of electronic features in a credit card-sized device without requiring a large power supply that would increase the form factor. This parameter change in power efficiency makes the invention feasible.
Solution Approach 2:
The OLED display serves multiple functions within the purchasing instrument: it displays visual information for users, provides security verification through dynamic patterns, and enables communication with payment terminals. This multi-functionality reduces the need for separate components that would increase the device's size, allowing electronic features to be integrated while maintaining the compact form factor.
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 OLED visual authentication circuit board enhances the usability for visually impaired users by providing larger and more discernible text, secure data management through dynamic light patterns, and reduced power consumption, while maintaining a compact form factor, thus addressing both usability and security concerns.
Implementation Method 1
A purchasing instrument may include a programmable array of organic light emitting diodes (“OLEDs”) that form an OLED display
Data Source
AI summary
A circuit board that includes OLED display technology is provided. An OLED display may present light patterns recognizable by a hearing or visually impaired users. The light pattern may be customized by the user. A specific workflow may be associated with a specific light pattern. A light pattern may visually guide a user through a workflow. For example, different menu options may be color coded. High consequence changes may flash with a certain light sequence or pattern. Trusted devices may present a specific light pattern or matrix at “login” time to confirm that the user is accessing a trusted device.
