Solution Overview

Problem

Existing multimedia recording devices require user intervention to start and stop recording, leading to missed important moments, and continuous recording consumes excessive resources.

Innovation Solution

A multimedia recording apparatus and method that includes a receiving unit, a normal recording unit, a pre-recording unit, and a combining unit, where the pre-recording unit automatically records ongoing multimedia information even when the normal recording mode is not active, allowing for seamless integration of pre-recorded content into the main recording data upon user instruction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If continuous recording is performed to capture all important moments, then recording completeness is improved, but resource consumption (power, memory) increases

Engineering Contradiction:

Improverecording completenessVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary recording actions by capturing pre-recording data before the user actually starts normal recording. This allows the system to be ready to capture important moments immediately when recording starts, without needing to continuously record beforehand, thus saving power while ensuring recording completeness.

Inventive Principle:

Principle #10Preliminary action

2Use of energy by moving object

If user intervention is required to start and stop recording, then resource consumption is reduced, but important moments may be missed

Engineering Contradiction:

Improvepower consumptionVSAvoidrecording completeness

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

3Reliability

If pre-recording is performed automatically to capture important moments, then recording completeness is improved, but device complexity increases

Engineering Contradiction:

Improverecording completenessVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The recording system is segmented into distinct functional units: a pre-recording unit that captures preliminary data, a normal recording unit for standard operation, and a combining unit that merges the two. This segmentation allows each unit to be optimized independently while working together to ensure complete recording without requiring complex integrated logic.

Inventive Principle:

Principle #1Segmentation

4Reliability

If pre-recording data is always combined with main recording data, then recording completeness is improved, but data processing complexity increases

Engineering Contradiction:

Improverecording completenessVSAvoiddata processing

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The combining unit operates autonomously to merge pre-recording data with normal recording data based on timing information without requiring complex user instructions or manual intervention. The system self-manages the data combination process by automatically identifying and integrating relevant pre-recording segments, reducing processing complexity while ensuring completeness.

Inventive Principle:

Principle #25Self-service

AI summary

A multimedia recording apparatus includes a receiving unit, a normal recording unit, a pre-recording unit and a combining unit. The receiving unit receives ongoing multimedia information. The normal recording unit generates first multimedia data under a normal recording mode. The pre-recording unit automatically records the ongoing multimedia information to generate a second multimedia data when the normal recording mode is not active. The combining unit adds content of the second multimedia data to the first multimedia data.
