Nested Biaxial Pivot Structure for Thin Display Holders

Solution Overview

Problem

Current biaxial pivots in display device holders are not favorable for lightweight designs, which is a challenge in meeting the demand for lightweight, thin, and small display device holders.

Innovation Solution

A biaxial pivoting mechanism with a mount component, rotatable connector, main body, and mount base configuration that allows for horizontal, vertical, and roll rotations, where the mount base is partially located in an accommodating space between the main body's surfaces, reducing the mechanism's thickness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If conventional biaxial pivot mechanisms are used in display device holders, then the holder can achieve multi-directional rotation functionality, but the holder becomes heavy and thick, which is unfavorable for lightweight and thin design requirements

Engineering Contradiction:

Improveweight of holderVSAvoidrotation functionality

Core Design Contradiction:

Weight of moving objectVSReliability

Solution Approach 1:

The mount base is partially located in the accommodating space of the main body, creating a nested structure where one component is embedded within another. This nesting arrangement reduces the overall thickness of the biaxial pivoting mechanism while maintaining all necessary rotation functions (horizontal rotation about first axis, vertical rotation about second axis, and roll rotation). The mount base fits into the accommodating space formed between the first surface and second surface of the main body, eliminating the need for separate mounting structures that would increase thickness.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Length of moving object

If conventional biaxial pivot mechanisms are used in display device holders, then the holder can achieve multi-directional rotation functionality, but the holder thickness increases, which is unfavorable for thin design requirements

Engineering Contradiction:

Improvethickness of holderVSAvoidrotation functionality

Core Design Contradiction:

Length of moving objectVSReliability

The mount base is partially located in the accommodating space of the main body, creating a nested structure where one component is embedded within another. This nesting arrangement reduces the overall thickness of the biaxial pivoting mechanism while maintaining all necessary rotation functions (horizontal rotation about first axis, vertical rotation about second axis, and roll rotation).

3Length of moving object

If the mount base is partially located in the accommodating space between the main body surfaces, then the thickness of the biaxial pivoting mechanism is significantly reduced, but the structural complexity increases

Engineering Contradiction:

Improvethickness of mechanismVSAvoidstructural complexity

Core Design Contradiction:

Length of moving objectVSDevice complexity

Solution Approach 1:

The mounting function and the main body structure are merged into a single integrated design. The mount base is integrated with the main body by partially locating it in the accommodating space, eliminating the need for separate mounting brackets or additional structural components. This merging reduces the number of parts and simplifies the overall structure while achieving thickness reduction.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The main body structure serves multiple functions simultaneously: it provides the accommodating space for the mount base, maintains the structural integrity for multi-directional rotation, and defines the overall geometry of the mechanism. The mount base also serves dual purposes as both a mounting component and a space-saving element that fits within the accommodating space.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A biaxial pivoting mechanism configured for connecting an object to a holder includes a mount component, a rotatable connector, a main body and a mount base. The mount component is configured to be fixed to the object. The rotatable connector is rotatably disposed on the mount component about a first axis. The main body is fixed to the rotatable connector. The mount base is configured to be fixed to the holder, and the main body is rotatably disposed on the mount base about a second axis not parallel to the first axis. The main body has a first surface, a second surface, and an accommodating space. The first surface is located closer to the rotatable connector than the second surface. The accommodating space extends to the second surface from the first surface. At least part of the mount base is located in the accommodating space.
