Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras without wireless communication functions cannot execute processing requests from external devices, limiting their functionality in wireless communication scenarios.
Innovation Solution
A memory card with a wireless communication function that includes a card interface unit, storage unit, wireless communication unit, processing determination unit, processing execution unit, and processing relay unit, allowing it to receive and execute processing requests from external devices and relay results back through wireless communication, even if the host digital camera lacks wireless communication capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication function is added to digital camera, then wireless communication capability is improved, but device complexity and cost increase
Solution Approach 1:
The memory card serves as an intermediary device that contains the wireless communication function. The memory card includes a wireless communication unit that can independently establish wireless connections with external apparatuses, allowing the digital camera to gain wireless capability without incorporating wireless communication hardware directly into the camera body.
Solution Approach 2:
The wireless communication function is segmented from the digital camera and placed in the memory card. This separation allows the camera to remain simple while the memory card handles all wireless communication tasks, including receiving processing requests and transmitting execution results.
2Productivity
If processing requests are handled by external apparatus only, then device complexity is reduced, but processing capability and functionality are limited
Solution Approach 1:
The system dynamically determines whether to execute processing requests locally or relay them to external apparatus based on the type of request. The memory card includes a processing determination unit that decides the execution location, allowing flexible adaptation to different processing scenarios without fixed architecture limitations.
3Ease of operation
If memory card handles all processing requests, then host equipment complexity is reduced, but memory card complexity increases
Solution Approach 1:
The memory card is designed with multi-functionality, serving both as a storage device and as a wireless communication controller. It can handle various types of processing requests (image processing, video processing, etc.) and dynamically delegate tasks between itself, the host equipment, and external apparatuses based on capability matching.

AI summary
A memory card with a wireless communication function may include a card interface (I/F) unit, a storage unit configured to store processing content information when the processing content information indicating processing content has been input from the host equipment to the card I/F unit; a wireless communication unit; a processing determination unit configured to determine whether or not the storage unit has stored the processing content information corresponding to processing request information when the wireless communication unit has received the processing request information transmitted from the external apparatus, a processing execution unit, and a processing relay unit configured to output the processing request information to the host equipment via the card I/F unit when the processing determination unit determines that the storage unit has stored the processing content information corresponding to the processing request information.
