Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional shock-absorbing brackets are used to reduce vibration, then the stability of the gimbal camera is improved, but the device complexity, volume, and weight increase

Engineering Contradiction:

Improvestability of the gimbal cameraVSAvoidcomplexity of the shock-absorbing bracket

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The shock-absorbing bracket is divided into multiple independent shock-absorbing elements (first and second types) that are separately connected to the mounting bracket and base. Each element functions independently to absorb vibrations from different directions, allowing the system to achieve effective shock absorption while maintaining a simpler overall structure compared to traditional integrated designs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial dimension by arranging shock-absorbing elements in specific three-dimensional configurations. The first shock-absorbing elements connect the mounting bracket to the base in one orientation, while the second shock-absorbing elements connect them in a different orientation, creating a multi-dimensional shock absorption system that improves stability without increasing complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If traditional shock-absorbing brackets are used to reduce vibration, then the stability of the gimbal camera is improved, but the volume and weight of the bracket increase

Engineering Contradiction:

Improvestability of the gimbal cameraVSAvoidweight of the shock-absorbing bracket

Core Design Contradiction:

ReliabilityVSWeight of stationary object

Solution Approach 1:

By segmenting the shock-absorbing function into multiple smaller independent elements rather than using a single large complex bracket, the overall weight is reduced while maintaining the shock absorption capability. Each element can be optimized for minimal weight while performing its specific function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes the structural parameters by using a modular arrangement of shock-absorbing elements with specific connection configurations. This allows for optimization of the weight parameter while maintaining the required stability performance through the strategic placement and orientation of the elements.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If traditional shock-absorbing brackets are used to reduce vibration, then the stability of the gimbal camera is improved, but the volume of the bracket increases

Engineering Contradiction:

Improvestability of the gimbal cameraVSAvoidvolume of the shock-absorbing bracket

Core Design Contradiction:

ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent utilizes three-dimensional spatial arrangement of shock-absorbing elements to achieve effective vibration reduction in a compact volume. By connecting elements between the mounting bracket and base in different orientations and dimensions, the system achieves comprehensive shock absorption without requiring a large overall bracket structure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The shock-absorbing elements are arranged in a nested configuration where multiple elements are positioned within the spatial envelope of the bracket structure, with elements connected between the mounting bracket and base in a compact arrangement that minimizes overall volume while maintaining functionality.

Inventive Principle:

Principle #7Nested doll (Nesting)
