Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electronic cards (contact or non-contact type) are used for data exchange, then data transmission functionality is achieved, but users cannot visually determine transaction status and are vulnerable to unauthorized data access
Solution Approach 1:
The patent applies light emission and color change principles by incorporating a light emitting module that displays different colors or light patterns to indicate transaction status. The card body includes a light transmissive portion that allows users to visually perceive the transaction state through color or light intensity changes, thereby providing real-time feedback on data exchange activities and enhancing security awareness.
Solution Approach 2:
The patent introduces a light guide module as an intermediary between the light emitting module and the external environment. This light guide module includes a light source focusing portion that directs and focuses the light from the emitting module through the light transmissive portion of the card body, making the internal light source visible to users while maintaining the card's compact structure.
2Loss of information
If light emitting modules are added to provide visual feedback, then transaction status visibility is improved, but device complexity increases
Solution Approach 1:
The patent merges the light emitting module, light guide module, and visual feedback function into a single integrated card body structure. The light emitting module is disposed within the card body and electrically connected to the electronic control module, while the light guide module is integrated into the same structure, allowing multiple functions (data exchange, light emission, and visual indication) to be combined in one compact device without significantly increasing overall complexity.
Solution Approach 2:
The card body serves multiple functions: it acts as the structural housing, contains the electronic control module for data exchange, houses the light emitting module for status indication, and includes the light guide module for light direction. This multi-functionality reduces the need for separate components and simplifies the overall device architecture.
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 light emitting electronic card effectively notifies users of transaction progress, enhancing security and user experience by visually indicating data exchange activities.
Implementation Method 1
The light guide module is disposed in the card body and corresponds to the light emitting module, includes a light source focusing portion that corresponds to the light transmissive portion, and guides a light source of the light emitting module to the light transmissive portion by the light source focusing portion
Data Source
AI summary
A light emitting electronic card includes a card body, an electronic control module, a light emitting module and a light guide module. The card body includes a panel, a base plate, a light transmissive portion, a first light shielding portion and a second light shielding portion. The electronic control module is disposed at the card body, and includes a circuit control carrier board and a non-contact type radio-frequency (RF) antenna or a contact type communication chip. The light emitting module is disposed in the card body and is electrically connected to the circuit control carrier board. The light guide module is disposed in the card body and corresponds to the light emitting module, includes a light source focusing portion corresponding to the light transmissive portion, and guides a light source of the light emitting module to the light transmissive portion by the light source focusing portion.
