Solution Overview

Problem

Conventional wall mounts for display devices are thick and costly due to the use of spring hinges for forward and backward movements and link structures for left and right movements, limiting their adjustability and compactness.

Innovation Solution

A wall mount design that allows for rotation in forward, backward, leftward, and rightward directions using a connector system with rotatable and movable supports, eliminating the need for spring hinges and link structures, resulting in a thinner, more cost-effective form factor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If spring hinges are used for forward and backward movements, then the wall mount can be rotated in forward and backward directions, but the thickness of the wall mount increases

Engineering Contradiction:

Improverotation capabilityVSAvoidthickness

Core Design Contradiction:

Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The patent extracts and eliminates the spring hinge component from the wall mount structure. Instead of using a spring hinge to enable forward and backward rotation, the invention uses a different mechanical structure consisting of a support arm and a support plate connected through a rotation axis, thereby achieving the same rotational function without the thickness increase associated with spring hinges.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the spring hinge mechanical system with an alternative mechanical system comprising a support arm, support plate, and rotation axis. This substitution maintains the rotational functionality while reducing the thickness of the wall mount by eliminating the need for a spring-based mechanism.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If link structures are used for left and right movements, then the wall mount can be rotated in leftward and rightward directions, but the thickness of the wall mount increases

Engineering Contradiction:

Improverotation capabilityVSAvoidthickness

Core Design Contradiction:

Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The patent extracts and eliminates the link structure component from the wall mount. Instead of using a link structure to enable left and right rotation, the invention employs a support arm and support plate connected through a rotation axis, achieving the same rotational function without the thickness increase that would result from incorporating a link structure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the link structure mechanical system with an alternative system consisting of a support arm, support plate, and rotation axis. This substitution preserves the left and right rotational functionality while reducing the wall mount's thickness by eliminating the need for a link-based mechanism.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If spring hinges and link structures are used, then the wall mount can be rotated in various directions, but the material costs increase

Engineering Contradiction:

Improverotation capabilityVSAvoidmaterial cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent extracts and eliminates the spring hinge and link structure components, which are typically expensive materials and components. By removing these elements and replacing them with a simpler support arm and support plate structure, the invention reduces material costs while maintaining multi-directional rotation capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs simpler, more cost-effective materials and components in place of expensive spring hinges and link structures. The support arm and support plate can be manufactured from standard materials at lower cost, making the wall mount more economically viable while preserving its functional capabilities.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
