Solution Overview

Problem

Existing adjustable mounts for heavy or touch-screen displays lack sufficient strength, rigidity, and ergonomics, often using friction joints that degrade over time and fail to securely lock displays in position, especially under external forces, and require cumbersome manual installation and adjustment.

Innovation Solution

A mount assembly with a base, tilt plate, and a position locking mechanism featuring a linkage member and lock that allows selective locking, combined with a counterbalance mechanism and quick-release system for easy mounting and dismounting, utilizing sturdy materials and heavy-duty pivotal connections to handle heavy loads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If friction joints are used to retain display in position, then the mount allows easy adjustment, but the joint degrades over time and fails to securely lock heavy displays

Engineering Contradiction:

Improveease of adjustmentVSAvoidjoint durability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces friction-based mechanical joints with a positive locking mechanism featuring interlocking teeth and pawls. This substitution eliminates the degradation issues of friction joints while maintaining ease of adjustment through simple pawl engagement and disengagement actions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The locking mechanism is segmented into discrete locking positions along the adjustment range, with each position secured by individual pawls engaging with teeth. This segmentation allows the display to be locked at multiple predetermined positions while ensuring secure retention at each position.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If existing adjustable mounts are used for heavy loads, then the mount structure is simple, but the mount lacks sufficient strength and rigidity

Engineering Contradiction:

Improvemount structure simplicityVSAvoidmount load capacity

Core Design Contradiction:

Device complexityVSStrength

Solution Approach 1:

The patent employs composite construction combining heavy-duty metal components for the locking mechanism and structural elements with friction-resistant materials at contact surfaces. This composite approach provides the necessary strength and rigidity for heavy loads while maintaining reasonable structural simplicity.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent incorporates curved and rounded contact surfaces in the locking mechanism, including spherical bearing surfaces and rounded edges on locking components. These curved surfaces distribute loads more effectively, increasing the overall strength and rigidity of the mount structure.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Force

If friction joints are tightened beyond operational range to handle heavy loads, then the mount can support heavier loads, but the joint components are damaged

Engineering Contradiction:

Improveload support capacityVSAvoidjoint component integrity

Core Design Contradiction:

ForceVSStrength

Solution Approach 1:

The patent replaces the friction-based tightening mechanism with a positive locking system using interlocking teeth and pawls. This mechanism provides secure load support through mechanical interlocking rather than friction, eliminating component damage from excessive tightening while maintaining heavy load capacity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If existing mounts lack secure locking capability, then the mount allows easy repositioning, but the display cannot be securely fixed in position

Engineering Contradiction:

Improverepositioning easeVSAvoidposition security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The adjustment range is segmented into discrete locked positions, with each position secured by spring-loaded pawls that engage with corresponding teeth. This segmentation enables easy repositioning by simply releasing and re-engaging the pawls at different segments, while ensuring secure fixation at each locked position.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The spring-loaded pawls automatically engage with the teeth when the display is moved to a new position, providing self-locking capability without requiring manual intervention. This self-service mechanism maintains position security while preserving ease of repositioning.

Inventive Principle:

Principle #25Self-service

AI summary

The present invention relates to adjustable mounts, and in particular to an adjustable mount that can be selectively locked in position by way of a position locking mechanism. The mount assembly generally comprises a base coupleable to a structure, a tilt plate coupleable to the device and pivotally connected to the base, and a position locking mechanism. The position locking mechanism generally comprises a linkage member extending between the base and the tilt plate, and a lock that is selectively adjustable between an unlocked state in which the linkage member is free to move relative the base thereby allowing the tilt plate to pivot about the base, and a locked state in which the linkage member is retained in position by the lock relative the base thereby preventing the tilt plate from pivoting about the base.
