Display Stand Locking Mechanism for Compact Packaging

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display device stands increase packaging thickness due to hinges, leading to higher storage and transportation costs, and require assembly after delivery, which can result in instability and damage.

Innovation Solution

A stand with a connecting member, insertion portion, hook step, supporting member, base, and locking unit that allows easy assembly and disassembly, reducing package volume and preventing shaking or damage, by enabling the connecting member to be fixed or separated from the base using a locking unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a hinge is used to rotate the base for packaging, then the display device can be folded for compact storage, but the package thickness increases due to the hinge width

Engineering Contradiction:

Improvepackage volumeVSAvoidpackage thickness

Core Design Contradiction:

Volume of moving objectVSLength of stationary object

Solution Approach 1:

The stand is divided into separate components: a base, a support, and a locking member. This segmentation allows the base and support to be completely separated for compact packaging, eliminating the need for a hinge and reducing package thickness while maintaining the ability to assemble into a stable structure when needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The locking member provides dynamic locking and unlocking functionality, allowing the stand to transition between assembled (stable) and disassembled (compact) states. The locking member can selectively engage with the support to fix it to the base, or be separated to allow compact packaging.

Inventive Principle:

Principle #15Dynamics

2Volume of moving object

If the base and support are completely separated for packaging, then the package volume is reduced, but assembly is required after delivery which may result in instability

Engineering Contradiction:

Improvepackage volumeVSAvoidstand stability

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The locking member is designed to be easily manipulated by the user without requiring tools or complex assembly procedures. The user can simply insert the locking member to engage the support with the base, or remove it to disassemble the stand, providing self-service assembly and disassembly while ensuring stable operation when assembled.

Inventive Principle:

Principle #25Self-service

3Reliability

If a locking mechanism is added to fix the support to the base, then the stand stability is improved, but the device complexity increases

Engineering Contradiction:

Improvestand stabilityVSAvoidassembly complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking function is extracted as a separate, independent locking member that can be easily added or removed. This separate locking component provides the necessary stability when assembled while maintaining simplicity, as the locking member operates independently without requiring complex mechanisms or additional assembly steps.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A stand for a display device includes a connecting member having a side connected to the display device, an insertion portion extending downward from the connecting member, a hook step formed on the insertion portion, a supporting member provided with a space in which the insertion portion is inserted, a base for fixing the supporting member, and a locking unit that is selectively aligned with the hook step to place the connecting member in a fixing or separable state in a state where the connecting member is disposed in the space.
