Solution Overview

Problem

Existing display stands face stability issues when a rotary unit is attached, as it shifts the centroid forward, reducing stability, and when not attached, the front legs obstruct user operations, failing to meet both usability and safety standards.

Innovation Solution

A stand system with a mounting plate module that allows the rotary unit to be attached or detached without changing the display's position relative to the stand, maintaining stability and preventing front leg obstruction, by adjusting the mounting positions to keep the centroid consistent with or without the rotary unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the centroid is set in a rear position to improve stability when the rotary unit is attached, then stability is improved, but the front legs of posts obstruct user operations when the rotary unit is not attached

Engineering Contradiction:
ImprovestabilityVSAvoiduser operations
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The mounting plate module is designed with a movable mechanism that allows it to shift position along the posts. When the rotary unit is attached, the mounting plate moves to a rear position that maintains stability. When the rotary unit is removed, the mounting plate moves to a front position that prevents obstruction of user operations on the display device. This dynamic adjustment resolves the contradiction between stability and ease of operation.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If an optional rotary unit is attached to enable orientation changing, then adaptability is improved, but the position of the display device moves forward and stability is reduced

Engineering Contradiction:
Improveorientation changingVSAvoidstability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The mounting plate module serves as an intermediary component between the posts and the display device. It is designed to accommodate the rotary unit while maintaining the overall centroid position. The mounting plate absorbs the dimensional changes introduced by the rotary unit through its movable design, preventing the display device from moving forward and maintaining stability while enabling orientation changes.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the front legs are positioned to improve usability when the rotary unit is not attached, then ease of operation is improved, but stability is reduced when the rotary unit is attached

Engineering Contradiction:
ImproveusabilityVSAvoidstability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The mounting plate module's position is dynamically adjusted based on whether the rotary unit is attached. When usability is the priority (rotary unit not attached), the mounting plate moves forward, allowing the front legs to be positioned optimally for user operations. When stability is the priority (rotary unit attached), the mounting plate moves rearward to maintain proper centroid positioning. This dynamic repositioning resolves the contradiction between usability and stability.

Inventive Principle:
Principle #15Dynamics

AI summary

A stand for supporting a display device includes multiple posts and a mounting plate module configured to connect the posts to each other. The stand is configured such that a rotary unit is attachable to and detachable from the mounting plate module, the display device is attachable to the mounting plate module via the rotary unit and is also attachable to the mounting plate module without the rotary unit, and a position of the display device relative to the stand in a depth direction in a state where the display device is attached to the mounting plate module via the rotary unit is the same as the position of the display device relative to the stand in the depth direction in a state where the display device is attached to the mounting plate module without the rotary unit.
