Solution Overview

Problem

Existing display devices face challenges in securely and easily attaching a stand to the back cover without using fastening members like screws, while also ensuring stability and ease of assembly and disassembly.

Innovation Solution

A display device design that includes a stand with a body, a head protruding into the back cover, and arms with hooks that couple to corresponding holes in the back cover, allowing for detachable coupling without screws, improved stability, and ease of assembly/disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a stand is attached to the back cover using fastening members like screws, then the coupling stability is improved, but the ease of assembly and disassembly deteriorates

Engineering Contradiction:
Improvecoupling stabilityVSAvoidease of assembly and disassembly
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The coupling structure is divided into separate components: the stand includes a body with arms that have hooks, while the back cover has corresponding holes. This segmentation allows the stand to be detached and reattached without fastening members, improving ease of assembly and disassembly while maintaining coupling stability through the hook-hole engagement mechanism.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a stand is attached without fastening members, then the ease of assembly and disassembly is improved, but the coupling stability deteriorates

Engineering Contradiction:
Improveease of assembly and disassemblyVSAvoidcoupling stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The stand's arms with hooks are positioned within the body structure, and the hooks engage with holes in the back cover. This nested arrangement allows the coupling components to be integrated into the overall structure, providing stable coupling without requiring separate fastening members, thus maintaining both ease of assembly and coupling stability.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If fastening members like screws are used to attach the stand, then the coupling stability is improved, but the device complexity increases

Engineering Contradiction:
Improvecoupling stabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fastening members (screws) are extracted from the coupling mechanism and replaced with an integrated hook-hole structure. The stand's arms with hooks are designed to directly engage with the back cover's holes, eliminating the need for separate fastening members and reducing device complexity while maintaining coupling stability.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If a complex fastening mechanism is used, then the coupling stability is improved, but the ease of manufacture deteriorates

Engineering Contradiction:
Improvecoupling stabilityVSAvoidease of manufacture
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The coupling mechanism uses simple geometric parameters (hooks with specific shapes engaging with corresponding holes) rather than complex fastening mechanisms. This allows for easier manufacturing through standard molding or machining processes while maintaining sufficient coupling stability for the application.

Inventive Principle:
Principle #35Parameter changes
