Multi-Card Data Recording and Integration Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras face inefficiencies in data transfer and management when using multiple memory cards, as existing techniques do not effectively integrate data from multiple recording media, leading to increased data transfer times and difficulty in managing distributed data.
Innovation Solution
A data recording apparatus and digital camera system that includes multiple recording media, data generating means, and data transfer means to integrate data from multiple cards into one medium, with a judging mechanism to ensure proper combinations of cards for efficient data allocation and transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is recorded in a distributed manner across multiple recording media, then data transfer time is reduced and recording efficiency is improved, but data management complexity increases and data integration becomes difficult
Solution Approach 1:
The patent divides recording data into multiple segments and distributes them across multiple recording media simultaneously, allowing parallel recording operations that reduce overall data transfer time while maintaining organized segment identification for later integration
Solution Approach 2:
The control unit acts as an intermediary that manages the distribution of data segments across multiple recording media, tracking which segments are stored where and coordinating the integration process, thereby reducing management complexity for the user
2Speed
If multiple recording media are used simultaneously, then recording speed is enhanced through parallel operations, but the difficulty of detecting and managing data locations increases
Solution Approach 1:
The control unit implements a feedback mechanism that continuously tracks and records the location of each data segment across multiple recording media, providing real-time information about data positions and enabling efficient retrieval and integration operations
3Ease of operation
If data is integrated from multiple recording media into one medium, then data management is simplified, but additional data transfer time is required during integration
Solution Approach 1:
The system performs preliminary organization and indexing of data segments during the initial distributed recording phase, preparing metadata and location information in advance that facilitates faster integration operations when data needs to be consolidated into a single recording medium
