Solution Overview

Problem

The existing attachment structures for display devices, such as those using deformable hooks, are complex and complicate assembly and disassembly processes, making them difficult to engage and disengage the display screen from the back plate efficiently.

Innovation Solution

A removable attachment structure comprising a movable module and a latching module, where the movable module can slide relative to the latching module, allowing for easy assembly and disassembly by sliding the display screen onto the latching subassembly, which is received in a receiving groove, facilitating engagement and disengagement with the backplane.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If deformable hooks are used to engage the display screen and back plate, then the attachment structure can provide secure connection, but the structure becomes complex and assembly/disassembly becomes difficult

Engineering Contradiction:

Improveconnection securityVSAvoidattachment structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The attachment structure is divided into separate components: a fixed module attached to the back plate and a movable module attached to the display screen. The fixed module contains receiving grooves that guide and receive the movable module, enabling secure connection through modular engagement rather than a single complex deformable hook structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The receiving groove acts as an intermediary element between the fixed module and movable module. It guides the movable module into proper position and provides a controlled path for engagement, simplifying the connection process while maintaining security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If deformable hooks are used for attachment, then connection can be maintained, but assembly and disassembly processes become complicated

Engineering Contradiction:

Improveattachment reliabilityVSAvoidassembly and disassembly ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The attachment structure employs a movable module that can slide along the receiving groove and a latching mechanism that can be actuated to lock or release the connection. This dynamic design allows easy assembly by simply sliding the modules together and easy disassembly by actuating the latch, while maintaining reliable connection when engaged.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Instead of using deformable hooks that require complex manipulation to engage and disengage, the invention inverts the approach by using a fixed receiving groove structure with a movable module that slides into place. The latching mechanism is designed to be actuated in a simple manner (pushing or pulling) rather than requiring complex hook manipulation.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If a simple attachment structure is used, then assembly and disassembly become easy, but the connection security may be compromised

Engineering Contradiction:

Improveassembly and disassembly easeVSAvoidconnection security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention converts the potential harm of a simple structure (insufficient connection security) into a benefit by using the simplicity of the receiving groove and movable module design to enable easy assembly, while the latching mechanism provides the necessary security. The ease of operation and connection security are both achieved through the complementary design of the simple guiding structure and the secure latching mechanism.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A removable attachment structure includes a movable module and a latching module. The movable module includes a first receiving groove. The latching module includes a first mounting portion and a latching subassembly on the first mounting portion. One end of the latching subassembly and the first mounting portion defines an entrance, the entrance allows the movable module to enter into or come out of the latching module. For latching, the movable module vertically enters into the entrance and is driven to the latching subassembly until the latching subassembly is completely received in the first receiving groove. For unlatching, the movable module is driven in opposite direction until the latching subassembly is disengaged from the latching part, thereby disengaging the movable module from the entrance.
