Solution Overview

Problem

Existing display devices face challenges in freely moving, maintaining standing stability, improving moving stability, reducing vibration, and effectively connecting the base and pole.

Innovation Solution

A display device with a stand comprising a base, a pole, and a wheel assembly, where the base includes weights and recessed portions for enhanced stability and mobility, and a connector system for electrical connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a display device is designed to be freely movable, then mobility is improved, but standing stability deteriorates

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

Solution Approach 1:

The base incorporates a wheel assembly that can transition between a retracted position (when the display device is stationary) and an extended position (when movement is needed). This dynamic configuration allows the base to adapt its structure: when the wheels are retracted, the base provides maximum stability for standing; when the wheels are extended, the display device becomes movable. The wheel assembly is configured to be rotatable relative to the base, enabling this dynamic transformation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The wheel assembly is nested within the base structure, with the wheels positioned in recessed portions of the base. When not in use for movement, the wheels are retracted into the base, becoming part of its internal structure. This nesting approach allows the movable components to be integrated into the base without compromising its external dimensions or standing stability when the wheels are not engaged.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If a wheel assembly is added to enable movement, then mobility is improved, but vibration increases

Engineering Contradiction:
ImprovemobilityVSAvoidvibration
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

A damping member is introduced as an intermediary element between the wheel assembly and the base. This damping member absorbs and dissipates vibrations generated by the wheel assembly during movement, preventing them from being transmitted to the main body of the display device. The damping member acts as a buffer that reduces the harmful vibrational effects while allowing the wheel assembly to function for mobility.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the base structure is reinforced to improve standing stability, then stability is improved, but device complexity increases

Engineering Contradiction:
Improvestanding stabilityVSAvoidbase structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The base is designed to serve multiple functions: it provides structural support for standing stability, houses the wheel assembly for mobility, contains the damping member for vibration reduction, and incorporates the weight for balance. By integrating these multiple functions into a single base structure rather than using separate components, the design achieves high stability without proportionally increasing complexity. The weight is strategically positioned within the base to simultaneously improve stability and balance.

Inventive Principle:
Principle #6Universality (Multi-functionality)
