Problem

Existing display device structures face limitations in design efficiency and assembly process, particularly in securely fastening the front cover to the main frame, which affects the overall rigidity and assembly efficiency.

Innovation Solution

A display device design that includes a main frame, a guide panel, and a front cover with specific protrusions and holes for secure coupling, utilizing a fastening member to attach the front cover to the rear surface of the main frame, enhancing structural integrity and assembly efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the front cover is coupled to the main frame using conventional coupling grooves and protrusions, then the assembly structure is simplified, but the rigidity and secure fastening of the display device is insufficient

Engineering Contradiction:
Improveassembly structureVSAvoidrigidity
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The front cover is divided into multiple separate pieces rather than a single unit, allowing each piece to be independently coupled to the main frame through specific coupling protrusions and grooves. This segmentation enables more distributed and secure fastening points while maintaining ease of assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling structure employs nested coupling protrusions and grooves where the front cover pieces are inserted into and secured by corresponding features on the main frame. This nesting mechanism provides secure fastening while maintaining a compact assembly structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Strength

If the front cover structure is redesigned with additional coupling features, then the rigidity and secure fastening is improved, but the device complexity increases

Engineering Contradiction:
Improvesecure fasteningVSAvoidstructure design
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The coupling protrusions and grooves are integrated directly into the front cover pieces and main frame structure, merging the fastening function with the structural components themselves. This eliminates the need for separate fastening mechanisms, reducing overall device complexity while maintaining secure fastening.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The front cover pieces serve multiple functions: they provide the front protective structure, contain internal components, and simultaneously act as coupling elements through integrated protrusions and grooves. This multi-functionality reduces the need for additional dedicated fastening components.

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

3Ease of operation

If conventional assembly methods are used, then the assembly process is simple, but the assembly efficiency and productivity are low

Engineering Contradiction:
Improveassembly processVSAvoidassembly efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The front cover pieces are pre-formed with integrated coupling protrusions and the main frame contains pre-positioned coupling grooves, allowing for quick and accurate alignment during assembly. This preliminary preparation of coupling features significantly speeds up the assembly process while maintaining simplicity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The coupling structure is designed to be self-aligning and self-securing, where the protrusions naturally fit into the grooves without requiring additional alignment tools or complex fastening operations. This self-service mechanism improves assembly efficiency while keeping the process simple.

Inventive Principle:
Principle #25Self-service
