Solution Overview
Problem
Traditional greeting cards lack a rich and engaging three-dimensional visual effect combined with electronic functions, limiting their festive and celebratory impact.
Innovation Solution
A three-dimensional electronic card is created by integrating a circuit board into a traditional three-dimensional card, incorporating an audio chip, speaker, power supply, and trigger switch, along with optional features like an iBeacon module and near-field communication (NFC) tag, to enhance sound and light effects and enable interactive functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic components are added to traditional greeting cards, then the festive and celebratory effects are enhanced, but the device complexity increases
Solution Approach 1:
The patent combines traditional three-dimensional card craftsmanship with electronic components (audio chips, speakers, lights, circuit boards) to create a hybrid greeting card that delivers both aesthetic visual effects and electronic audio-visual functions, thereby enhancing festive impact while managing complexity through integration
Solution Approach 2:
The greeting card is designed to perform multiple functions: traditional visual display through three-dimensional structures, audio playback through speakers and audio chips, lighting effects through LEDs, and wireless communication through NFC or iBeacon modules, making it a multi-functional celebratory device
2Reliability
If a circuit board with multiple electronic components is integrated into the card, then sound and light effects are enhanced, but the manufacturing complexity increases
Solution Approach 1:
The card is divided into distinct functional modules: a three-dimensional assembled portion for visual display, a circuit board for electronic control, audio components for sound output, and optional wireless communication modules, allowing each segment to be manufactured and tested separately before final assembly
Solution Approach 2:
A circuit board serves as an intermediary component that coordinates between various electronic elements (audio chip, speaker, lights, wireless modules) and the power supply, simplifying the manufacturing process by providing a centralized control platform rather than requiring direct integration of all components
3Adaptability or versatility
If wireless communication modules are added to enable interactive functionality, then the interactivity is improved, but the device complexity increases
Solution Approach 1:
The card incorporates universal wireless communication interfaces (NFC and iBeacon) that enable multiple types of interactions: data exchange with smartphones, location-based services, and remote control of audio-visual functions, allowing a single device to serve multiple interactive purposes without requiring separate specialized components for each function

AI summary
The present application discloses a three-dimensional electronic card including a first sheet-like portion and a second sheet-like portion which are foldably connected together, and a three-dimensional assembled portion connected between the first sheet-like portion and the second sheet-like portion. The three-dimensional assembled portion can be erected and formed into a three-dimensional structure when the first and second sheet-like portions are unfolded, and can be folded up, formed into a sheet-like structure, and held between the first and second sheet-like portions when the first and second sheet-like portions are folded. The first or second sheet-like portion is provided with a circuit board. The circuit board is provided with an audio chip, a speaker and a power supply. The first or second sheet-like portion is further provided with a trigger switch electrically connected to the circuit board. The trigger switch is activated to operate the speaker.
