Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for automatically determining recording timing in electronic devices like cameras and smart glasses often fail to capture highlights as intended by the user, leading to missed recording opportunities.

Innovation Solution

An electronic device that acquires eyeball information to determine the user's state and records images based on predetermined conditions, such as excitement or attention levels, to automatically capture highlights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If recording timing is determined automatically based on user nervousness or device movement, then the user can capture highlights without manual intervention, but highlights may still be missed when the user wishes to record them

Engineering Contradiction:

Improveautomatic recording timing determinationVSAvoidhighlight recording accuracy

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The patent replaces mechanical/direct sensing methods (nervousness detection, movement sensing) with optical sensing (eyeball information detection) to determine recording timing. The eyeball detection unit captures eye movement data, which serves as a more reliable indicator of user intent to record highlights, resolving the contradiction between automation and reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If the user manually designates recording timing, then recording accuracy is high, but the user cannot record highlights when focused on visually recognizing scenery

Engineering Contradiction:

Improverecording timing accuracyVSAvoiduser operation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs self-service by automatically detecting user intent through eyeball information and autonomously determining recording timing. This eliminates the need for manual user intervention while maintaining high recording accuracy, as the system interprets user gaze patterns to identify highlight moments independently.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback from eyeball detection data to continuously adjust and determine optimal recording timing. By monitoring user eye movements and gaze duration, the system receives real-time feedback about user attention and intent, enabling accurate automatic recording decisions without manual input.

Inventive Principle:

Principle #23Feedback

3Reliability

If eyeball information is acquired to determine recording timing, then highlight recording reliability improves, but device complexity increases

Engineering Contradiction:

Improvehighlight recording accuracyVSAvoideyeball detection system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The eyeball detection unit serves multiple functions: it detects user intent for recording, determines recording timing, and can potentially track user attention patterns. This multi-functionality justifies the added complexity by providing a single component that delivers reliable highlight recording while offering potential future extensions.

Inventive Principle:

Principle #6Universality (Multi-functionality)
