Electronic Greeting Card With Embedded Multimedia Player
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing greeting cards lack versatility in accommodating diverse multimedia content and fail to maintain utility and entertainment value beyond the initial communication, as they do not effectively integrate digital multimedia elements with traditional printed materials.
Innovation Solution
The integration of a digital multimedia player within a conventional greeting card structure, allowing for the reception, playback, and replay of digital multimedia files, including graphics and audio, which can be selected or created by the sender and loaded via various data connections or storage devices, combining with printed elements for a comprehensive media message.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital multimedia content is integrated into greeting cards, then communication value and entertainment value are enhanced, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent implements a universal digital multimedia player that can accommodate various types of digital content (images, audio, video, animations) and work with different greeting card designs. The player uses standard interfaces (USB, SD card, wireless connectivity) to receive diverse multimedia files, allowing a single device to handle multiple content types and occasions, thereby achieving content versatility without proportionally increasing complexity
Solution Approach 2:
The digital multimedia player is embedded within the greeting card structure, with the card panels serving as both the physical greeting card and the housing for the digital player. The display screen is integrated into the card front panel, and control buttons are incorporated into the card structure. This nesting approach allows the multimedia functionality to be contained within the familiar greeting card form factor, adding versatility while minimizing increases in overall device complexity
2Duration of action of stationary object
If digital multimedia player is integrated into greeting card, then utility and entertainment value are maintained long-term, but manufacturing precision and production difficulty increase
Solution Approach 1:
The system is divided into separate functional modules: a reusable digital multimedia player unit and interchangeable greeting card panels. The player contains all electronic components (display, processor, storage, power), while the card panels serve as protective housings and interface elements. This segmentation allows the electronic components to be manufactured and tested independently with standardized precision requirements, while the card panels can be produced using conventional printing and cardmaking techniques, thereby reducing overall manufacturing precision demands while enabling long-term utility through the durable reusable player
Solution Approach 2:
The digital multimedia player is pre-configured with the necessary software, file management capabilities, and playback functions before being combined with the greeting card panels. The device includes pre-installed support for multiple file formats and playback modes. This preliminary preparation of the electronic component allows for standardized manufacturing processes with clear quality control checkpoints, reducing the need for complex post-assembly calibration and testing, thus lowering manufacturing precision requirements while ensuring the device maintains utility over an extended period
3Ease of operation
If conventional greeting card structure is used with digital player, then ease of operation is maintained, but adaptability to diverse content is reduced
Solution Approach 1:
The digital multimedia player incorporates universal content reception capabilities through multiple interfaces (USB port, SD card slot, wireless connectivity) that can accept various file formats and content types. The playback system supports images, audio, video, and animations, allowing the same device to handle diverse content while maintaining the simple operation of a greeting card - the user simply inserts the card or connects the device and the content plays automatically or through basic controls
Data Source
AI summary
Electronic greeting cards include a greeting card with two or more interconnected panels in combination with a digital multimedia player device which includes an electronic display and an audio output, and circuitry which is operative to receive, store and play digital multimedia files and content. The various greeting card structures cover and encapsulate or otherwise house and adorn the digital multimedia player. Digital files are loaded on to the digital multimedia player by a connection to a network, or directly from a data storage device such as an SD card or USB connection or compact flash which interfaces with a port in the digital multimedia player. Pre-recorded digital multimedia greeting card content is either pre-loaded on a portable data storage device, or selected for purchase and downloaded or transferred for replay by the digital multimedia player of the electronic greeting card.
