Solution Overview

Problem

Current assembly methods for display devices, such as between a front bezel and a back plate, face challenges due to size tolerances and assembly tolerances, leading to an incongruous appearance when the front bezel is white and the display shows a white picture, as the black matrix is noticeable.

Innovation Solution

An assembly structure comprising a first assembly member with protruding portions and a second assembly member with restraining portions, along with retaining members, allows for adjustable relative positioning without the need for specific tools, enabling precise alignment and efficient assembly by using relative offsets to ensure accurate placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional assembly methods are used for display devices, then assembly can be completed with standard procedures, but assembly position accuracy is poor due to size tolerances and assembly tolerances

Engineering Contradiction:
Improveassembly position accuracyVSAvoidassembly structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The assembly structure is segmented into protruding portions on the front bezel and corresponding restraining portions on the back plate, with multiple discrete offset positions provided. This segmentation allows selective assembly at different offset positions to compensate for tolerance variations, thereby improving assembly position accuracy without requiring complex adjustment mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protruding portions and restraining portions are pre-configured with specific geometric shapes and multiple offset positions during manufacturing. This preliminary action eliminates the need for complex real-time adjustments during assembly, as the correct offset position can be directly selected based on pre-determined tolerance compensation requirements.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If multiple adjustments are made to achieve accurate positioning, then assembly position accuracy improves, but assembly time increases

Engineering Contradiction:
Improveassembly position accuracyVSAvoidassembly efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

Multiple offset positions are pre-configured on the protruding portions and restraining portions during manufacturing. This allows assemblers to directly select and assemble at the appropriate offset position without requiring iterative adjustments, thereby improving assembly position accuracy while maintaining high assembly efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The assembly structure enables self-positioning through the predetermined offset positions. The protruding portions and restraining portions are designed to automatically align at the correct offset position during assembly, eliminating the need for complex external adjustment tools or procedures and reducing assembly time.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If precise positioning is achieved through complex adjustment mechanisms, then assembly position accuracy improves, but device complexity increases

Engineering Contradiction:
Improveassembly position accuracyVSAvoidassembly structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The positioning function is segmented into discrete offset positions provided by the protruding portions and restraining portions. This segmentation replaces complex continuous adjustment mechanisms with simple discrete position selection, achieving accurate positioning while minimizing structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protruding portions and restraining portions are designed as simple, inexpensive geometric features that can be directly formed during manufacturing. These replace expensive and complex adjustment mechanisms, achieving precise positioning through simple structural elements that require no additional adjustment tools or procedures.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

An assembly structure includes a first assembly member, a second assembly member and a retaining member. The first assembly member includes a plurality of protruding portions and each of the protruding portions has a recess. The second assembly member includes a plurality of restraining portions. The restraining portions are disposed with respect to the protruding portions by a plurality of relative offsets and the relative offsets are different from each other. Each of the restraining portions is capable of passing through the recess of the protruding portion correspondingly. The retaining member is disposed on one of the protruding portions and covers the recess correspondingly. When the second assembly member is assembled to the first assembly member, one of the restraining portions abuts against the retaining member.
