Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple cameras are used to capture stereoscopic images, then the stereoscopic effect is improved, but the device complexity and operation difficulty increase significantly

Engineering Contradiction:
Improvestereoscopic image qualityVSAvoidcamera system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple lenses into a single camera body, integrating what would traditionally require multiple separate cameras into one unified device. The camera includes a lens array with multiple lenses arranged in specific patterns, allowing simultaneous capture of multiple viewpoint images without requiring multiple independent camera systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the optical system into multiple discrete lenses within a single camera, where each lens captures images from different viewpoints. This segmentation allows the complex function of multiple cameras to be achieved through divided optical elements that can be precisely controlled by individual driving modules.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple cameras are arranged in a rig for multi-view shooting, then multi-view images are captured, but the volume and weight of the device increase

Engineering Contradiction:
Improvemulti-view capturing capabilityVSAvoidcamera rig volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent nests multiple lenses within a single camera body structure, placing lens arrays inside what would traditionally be a single-camera housing. This nesting approach allows multiple optical systems to occupy the same physical space that would otherwise contain only one camera, dramatically reducing overall device volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent arranges multiple lenses in specific spatial patterns (such as arc arrays or planar arrays) within the camera body, utilizing three-dimensional space efficiently. By positioning lenses at different locations and orientations within the compact camera housing, the system achieves multi-view capturing capability without proportionally increasing device volume.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Measurement precision

If professional cameras or broadcasting equipment are used for stereoscopic image capture, then image quality is improved, but the cost and skill requirement increase

Engineering Contradiction:
Improveimage capturing precisionVSAvoiddevice accessibility
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent incorporates automatic control systems with driving modules that autonomously adjust lens positions and focusing without requiring manual intervention. The camera automatically captures images from multiple viewpoints and processes the data, eliminating the need for professional operators to manually coordinate multiple cameras or perform complex post-processing.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment systems with automated driving modules that use motors or other actuation mechanisms to precisely position lenses and control focusing. This substitution of manual mechanical operations with automated systems maintains high precision while dramatically simplifying user interaction and reducing skill requirements.

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

4Adaptability or versatility

If a large number of cameras are used for multi-view shooting, then the stereoscopic coverage is improved, but the data processing burden increases

Engineering Contradiction:
Improvestereoscopic coverageVSAvoiddata processing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary organization and sorting of multi-view images during the capture process itself, using the controller to manage data from multiple lenses as they are acquired. By pre-organizing the data structure and applying processing algorithms during capture rather than after, the system reduces the computational burden of post-processing while maintaining comprehensive stereoscopic coverage.

Inventive Principle:
Principle #10Preliminary action
