Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional shock-absorption springs are used in damping arms, then basic shock absorption is provided, but camera shaking and lateral inertia cannot be effectively controlled during filming

Engineering Contradiction:

Improvecamera stabilityVSAvoiddamping arm structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The damping arm is divided into multiple functional segments: a connector for mounting, a moving member with degrees of freedom, and a shock-absorption structure with buffering components. This segmentation allows each part to specialize in specific shock absorption functions, improving overall camera stability while keeping individual components manageable in complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The moving member is designed with multiple degrees of freedom, allowing it to dynamically adjust its position and orientation in response to camera shaking and lateral inertia forces. This dynamic capability enables the damping arm to effectively counteract various方向的 vibrations while maintaining adaptability to different filming conditions.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If the damping arm structure is simplified, then manufacturing becomes easier, but the ability to prevent camera detachment under variable road conditions deteriorates

Engineering Contradiction:

Improvedamping arm fabricationVSAvoidcamera attachment security

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The buffering component is nested within the moving member structure, with the shock-absorption structure integrated into the overall damping arm assembly. This nested design allows multiple functions to be combined in a compact manner, maintaining attachment security without excessive structural complexity or manufacturing difficulty.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The moving member acts as an intermediary between the connector and the camera, providing a flexible connection that can absorb shocks and vibrations. This intermediary structure secures the camera while accommodating road variations, maintaining reliability without requiring overly complex direct mounting solutions.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If rigid connection is used between connector and supporting member, then structural stability is ensured, but camera shaking and inertial forces cannot be effectively buffered

Engineering Contradiction:

Improvestructural stabilityVSAvoidcamera shaking

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The shock-absorption structure with buffering components is pre-configured to anticipate and counteract camera shaking and inertial forces before they cause detachment or excessive movement. This preliminary buffering action maintains structural stability while protecting against harmful vibrations during filming.

Inventive Principle:

Principle #10Preliminary action

4Reliability

If the shock-absorption structure is made more complex to control centrifugal force, then camera stability improves, but device complexity increases

Engineering Contradiction:

Improvecamera stabilityVSAvoidshock-absorption structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The shock-absorption function is segmented into specific buffering components within the moving member, rather than requiring a completely complex overall structure. This segmentation allows centrifugal force control to be achieved through targeted components, improving camera stability without proportionally increasing overall device complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The moving member with multiple degrees of freedom serves itself to control centrifugal force and buffer vibrations through its inherent dynamic characteristics. This self-service capability reduces the need for additional complex active control mechanisms, maintaining camera stability while limiting device complexity growth.

Inventive Principle:

Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The shock-absorption head effectively mitigates camera shaking and inertial shifts, preventing detachment and ensuring the stability of captured footage by autonomously adjusting to counteract centrifugal forces.

Implementation Method 1

The buffering component incorporates at least one first slider and a second slider, both arranged in parallel with a vertical orientation. Each slider is equipped with two elastic components. The external structure smoothly slides onto the second slider, clamping between the two elastic components of the second slider.

Methodology Applied

Scientific EffectElasticity: Elasticity

Implementation Method 2

In this patent, the elastic components are realized through springs. As the gimbal moves along the direction parallel to the first slider or the second slider, the springs undergo compression or extension, effectively slowing down the lateral or longitudinal movements of the camera mounted on the gimbal, thereby achieving effective shock absorption.

Methodology Applied

Scientific EffectSpring: Spring

Implementation Method 3

The external structure smoothly slides onto the second slider, clamping between the two elastic components of the second slider. The second slider then seamlessly slides onto the first slider, clamping between the two elastic components of the first slider.

Methodology Applied

Scientific EffectFriction: Friction

AI summary

A shock-absorption head includes a connector, a moving component, a supporting component, and a shock-absorption structure. The shock-absorption head can induce a swaying motion in the supporting component, counteracting any tendency of a camera to swing. This motion, facilitated by the shock-absorption structure's telescopic movement, effectively mitigates the centrifugal force resulting from the camera's oscillation. The shock-absorption head can minimize the risk of detachment between the camera and the shock-absorption arm, thereby preventing camera instability and ensuring the steadiness of the captured image.
