Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If professional moving shot operations are used to achieve specific video effects, then video quality and effect are improved, but operation complexity and hardware requirements increase

Engineering Contradiction:
Improvevideo effect qualityVSAvoidoperation complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system performs automatic target tracking and camera movement control without requiring professional operators. The electronic device autonomously identifies targets, calculates movement trajectories, and executes camera movements based on predefined templates, enabling ordinary users to achieve professional video effects through simple operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system provides predefined moving shot templates that are prepared in advance. These templates include various camera movement patterns and tracking behaviors that have been pre-configured, allowing users to directly apply professional video effects without needing to understand complex operation procedures or perform manual trajectory planning.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If professional moving shot operations are used to achieve specific video effects, then video quality and effect are improved, but cost increases due to extra labor and equipment

Engineering Contradiction:
Improvevideo effect qualityVSAvoidcost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The system uses virtual AR anchors and software-based tracking algorithms to replicate professional camera movement effects without requiring physical camera rigs, stabilizers, or specialized equipment. The virtual markers and computational methods provide a cost-effective alternative to expensive hardware solutions.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system replaces mechanical camera movement systems with software-based control. Instead of using physical equipment to achieve complex camera movements, the system uses algorithmic trajectory calculation and electronic image stabilization to produce the same effects, eliminating the need for specialized hardware.

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

3Adaptability or versatility

If manual camera movement operations are used, then flexibility in creating custom shots is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveshot flexibilityVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system provides dynamically adjustable parameters within predefined templates. Users can modify tracking speed, movement range, and other parameters to adapt the camera movement to different shooting scenarios, while still benefiting from the automated control that maintains ease of operation.

Inventive Principle:
Principle #15Dynamics

AI summary

A photography method, includes: receiving an instruction of launching to collect images; establishing an AR anchor in an image viewfinder of the electronic device, the AR anchor corresponding to a position of a photographed object in a virtual three-dimensional space; generating a moving shot track in the image viewfinder based on a current position of the camera module and the AR anchor, the moving shot track representing a desired moving route of the camera module in the virtual three-dimensional space; and performing image collection on the photographed object based on the moving shot track.
