Information Capture Device Cyclic Recording Storage Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information capture devices face issues with data loss due to user forgetfulness or malicious deletion/damage, as existing control methods do not adequately protect recorded data from being arbitrarily removed or damaged.
Innovation Solution
An information capture device and control method that implement a cyclic recording process, where a designated storage capacity is set and used exclusively for cyclic recording, preventing data from being deleted or damaged, while allowing common information abstraction to continue using the remaining spare capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a person wearing an information capture device forgets to activate the device or if abstracted data is maliciously deleted or damaged, then the abstracted data can be lost, but implementing protection mechanisms may increase device complexity
Solution Approach 1:
The storage space is segmented into a dedicated cyclic recording storage area and a common information abstraction storage area. The cyclic recording storage area is specifically designated for protected recording and cannot be arbitrarily deleted or damaged, while the common storage area allows normal information abstraction operations. This segmentation resolves the contradiction by providing targeted protection without requiring system-wide complexity increases.
Solution Approach 2:
A control unit acts as an intermediary between the storage unit and the recording processes. The control unit manages the cyclic recording policy, allocates storage capacities, and enforces protection mechanisms. By introducing this intermediary controller, the system achieves reliable data protection through centralized management without requiring complex hardware modifications.
2Reliability
If a designated storage capacity is set exclusively for cyclic recording, then data protection is improved, but the flexibility of storage usage may be reduced
Solution Approach 1:
The storage space is divided into distinct segments: a cyclic recording storage area with dedicated capacity for protected recording and a common storage area for flexible information abstraction. This segmentation allows the system to maintain data integrity in the cyclic recording area while preserving storage flexibility in the common area, resolving the contradiction between protection and adaptability.
Solution Approach 2:
Different storage areas are assigned different qualities and characteristics. The cyclic recording storage area has the quality of being protected and immutable, while the common storage area has the quality of being flexible and modifiable. This local differentiation allows the system to simultaneously achieve data integrity and storage flexibility without compromising either aspect.
3Productivity
If cyclic recording and common information abstraction run simultaneously, then productivity is improved, but storage capacity management becomes more complex
Solution Approach 1:
The storage space is segmented into dedicated areas for cyclic recording and common information abstraction, allowing both processes to run simultaneously without interfering with each other. The control unit manages storage capacity allocation between these segments, enabling parallel operations while simplifying capacity management through clear spatial separation of functions.

AI summary
An information capture device includes a camera member, a storage unit, a network module and a processing unit. The camera member captures an ambient environment to generate an environment image stream of the ambient environment. The storage unit has a storage space. The network module receives a cyclic recording policy through a network, wherein the cyclic recording policy includes an activation instruction and a storage capacity setting. The processing unit calculates a designated storage capacity according to the storage capacity setting and a total capacity of the storage space, detects a spare capacity of the storage space according to the designated storage capacity, limits the designated storage capacity to be used exclusively for the cyclic recording process, and activates and executes the cyclic recording process according to the activation instruction when the spare capacity satisfies the designated storage capacity.
