Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If sensor measurement method is used to detect movement tracks, then detection precision is improved, but the accessible volume of movement target increases

Engineering Contradiction:
Improvemovement track detection precisionVSAvoidaccessible volume of movement target
Core Design Contradiction:
Measurement precisionVSVolume of moving object

Solution Approach 1:

The patent introduces a camera as an intermediary device to capture movement tracks from a distance, eliminating the need to mount sensors on the movement target itself. The camera captures images of the target's movement path, and image processing algorithms analyze these images to determine the track, achieving precise detection without increasing the target's accessible volume.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical sensor mounting approach with an optical imaging system. Instead of using physical sensors attached to the target, the system uses cameras to capture visual information and computational algorithms to extract movement track data, substituting mechanical measurement with optical and computational methods.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Volume of moving object

If sensor with small volume is used, then accessible volume of movement target is maintained, but economic cost increases

Engineering Contradiction:
Improveaccessible volume of movement targetVSAvoideconomic cost
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The patent uses camera images as a copy or representation of the movement target's position and path. Instead of directly measuring the target with expensive small sensors, the system captures visual copies of the target's movement and processes these images to extract the required track information, reducing hardware costs while maintaining measurement capability.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces expensive mechanical sensors with a more economical optical imaging system. The camera-based approach, combined with image processing algorithms, provides a cost-effective alternative to using small, expensive sensors mounted on the target, achieving the same measurement function with lower economic cost.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If dynamic balance evaluation method is used, then overall motion evaluation is achieved, but collision results in different areas cannot be measured

Engineering Contradiction:
Improveevaluation efficiencyVSAvoidcollision detection precision in different areas
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent segments the movement path into multiple discrete points or segments along the trajectory. By dividing the continuous movement path into segments, the system can independently analyze each segment for collision detection, allowing precise measurement of collision results in different areas while maintaining efficient overall evaluation through automated processing of each segment.

Inventive Principle:
Principle #1Segmentation

AI summary

Embodiments of the present application provide a human-computer interaction movement track detection method, device, apparatus, and computer-readable storage medium. The method comprises segmenting a movement path to obtain one or more sub paths; monitoring and recording movement of a movement target in each of the sub paths so as to obtain an interactive movement track of the movement target in each of the sub paths; identifying the interactive movement track of the movement target in each of the sub paths via a determination model corresponding to each of the sub paths; based on identification of the human-computer interaction movement track of each of the sub paths, completing human-computer interaction movement track detection on the movement target. In this way, detection accuracy of the human-computer interaction movement track is improved.
