Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing camera systems struggle to detect small or high-frequency vibrations due to limitations in frame rate and field of view, often missing critical motion data when capturing large areas.

Innovation Solution

Capture multiple synchronized recordings of smaller sections of the target area, then combine them to create a composite video at higher frame rates, using synchronization methods like external electronic signals or object motion as a reference.

1Area of stationary object

If the camera captures a full field of view at a specific frame rate, then the entire area of interest is covered, but the frame rate is insufficient to capture high-frequency vibrations

Engineering Contradiction:

Improvefield of viewVSAvoidframe rate

Core Design Contradiction:

Area of stationary objectVSProductivity

Solution Approach 1:

The patent divides the full field of view into multiple smaller sections and captures video recordings of each section separately. By segmenting the field of view, each recording can be captured at a higher frame rate than would be possible for the entire field of view, enabling detection of high-frequency vibrations while still covering the complete area through composite video creation.

Inventive Principle:

Principle #1Segmentation

2Productivity

If the field of view is reduced to a smaller area, then the frame rate increases, but the entire area of interest is not captured

Engineering Contradiction:

Improveframe rateVSAvoidfield of view

Core Design Contradiction:

ProductivityVSArea of stationary object

Solution Approach 1:

The field of view is segmented into multiple sections that are captured sequentially at high frame rates. The composite video synthesis combines these segmented recordings to reconstruct the complete field of view, thereby achieving both high frame rate and full area coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single simultaneous capture of the entire field of view to a temporal dimension approach, where multiple recordings are taken sequentially at different time points. This dimensional shift allows high frame rates to be achieved while still capturing the complete area through temporal composition.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Productivity

If multiple recordings of different sections are captured, then high frame rate is achieved, but synchronization between recordings becomes complex

Engineering Contradiction:

Improveframe rateVSAvoidsynchronization

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent employs feedback mechanisms through synchronization references (such as external triggers or detected object motion) to coordinate the capture timing of multiple recordings. This feedback-based synchronization ensures that recordings from different sections are temporally aligned, facilitating accurate composite video creation without excessive complexity.

Inventive Principle:

Principle #23Feedback
