Solution Overview

Problem

Existing supports for videophotographic equipment are either unstable due to uneven surfaces or require laborious adjustments, making it difficult to maintain equipment positioning and framing, especially with heavy equipment or uneven surfaces.

Innovation Solution

A compact support with a plate and three rotatable legs that can be adjusted continuously and independently to any desired inclination, using springs to maintain stability without the need for locking mechanisms, allowing for versatile positioning on various surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a compact support with four bearing points is used, then the support is stable on flat surfaces, but it becomes unstable on uneven surfaces

Engineering Contradiction:
ImprovestabilityVSAvoidadaptability to uneven surfaces
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The support is divided into three independent legs instead of a rigid four-point base. Each leg can be adjusted independently in length and angle, allowing the support to adapt to uneven surfaces while maintaining stability through the triangular configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The legs are made movable and adjustable rather than fixed. Each leg can be independently positioned and locked at different angles and lengths, transforming the static four-point support into a dynamic three-legged structure that adapts to various surface conditions.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If three legs are used instead of four, then adaptability to uneven surfaces improves, but adjustment becomes laborious and locking mechanisms are required

Engineering Contradiction:
Improveadaptability to uneven surfacesVSAvoidease of adjustment
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The support leverages the inherent stability of the triangular configuration formed by the three legs and the plate. This geometric self-locking property eliminates the need for additional locking mechanisms, making the structure self-stabilizing once the legs are positioned.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Each leg is equipped with specific adjustment features at its connection points, allowing independent adjustment of length and angle. This localized adjustability maintains ease of operation while enabling adaptation to uneven surfaces through the three-legged configuration.

Inventive Principle:
Principle #3Local quality

3Stability of the object's composition

If locking mechanisms are added to fix leg positions, then position stability during use improves, but device complexity increases

Engineering Contradiction:
Improveposition stabilityVSAvoidcomplexity of locking mechanisms
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The support leverages the inherent stability of the triangular configuration formed by the three legs and the plate. This geometric self-locking property eliminates the need for additional locking mechanisms, making the structure self-stabilizing once the legs are positioned.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Instead of adding locking mechanisms to prevent movement, the design uses the natural geometric stability of the three-legged triangular configuration to inherently maintain position. The structure is designed to be stable by default through its configuration rather than through added locking components.

Inventive Principle:
Principle #13The other way round (Inversion)

4Measurement precision

If continuous adjustment of leg inclination is enabled, then positioning precision improves, but ease of operation decreases due to lack of fixed positions

Engineering Contradiction:
Improvepositioning precisionVSAvoidease of positioning
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The legs are made movable and adjustable rather than fixed. Each leg can be independently positioned and locked at different angles and lengths, transforming the static four-point support into a dynamic three-legged structure that adapts to various surface conditions.

Inventive Principle:
Principle #15Dynamics
