Solution Overview

Problem

Existing display apparatuses require separate fasteners to attach boards to the rear chassis, which increases material costs and operational complexity.

Innovation Solution

A display apparatus design that allows direct attachment of boards to the rear chassis using an insertion rib and fixing protrusion mechanism, eliminating the need for separate fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate fasteners are used to attach boards to the rear chassis, then the attachment is secure, but the material cost and operational complexity increase

Engineering Contradiction:

Improveattachment securityVSAvoidfastener configuration

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the fastening function into the board structure itself by integrating a fixing protrusion directly on the board that engages with a fixing groove on the rear chassis. This eliminates the need for separate fasteners while maintaining secure attachment, directly resolving the contradiction between attachment security and device complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The board performs its own fastening function through the self-contained fixing protrusion and groove mechanism. The board is self-sufficient in securing itself to the rear chassis without requiring external fasteners, reducing both material costs and operational complexity while maintaining reliable attachment

Inventive Principle:

Principle #25Self-service

2Reliability

If separate fasteners are used to attach boards to the rear chassis, then the attachment is secure, but material costs increase

Engineering Contradiction:

Improveattachment securityVSAvoidmaterial cost

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The fastening function is merged into the board structure through the integrated fixing protrusion, eliminating the need for separate fastener components. This reduces material costs while maintaining secure attachment through the built-in fixing mechanism

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The board serves its own fastening needs through the self-contained fixing protrusion and groove system, eliminating the need for additional fastener materials and reducing overall material costs while ensuring reliable attachment

Inventive Principle:

Principle #25Self-service

3Area of moving object

If board size is reduced, then space efficiency improves, but the area for circuit components and patterns is restricted

Engineering Contradiction:

Improveboard sizeVSAvoidcircuit configuration flexibility

Core Design Contradiction:

Area of moving objectVSAdaptability or versatility

Solution Approach 1:

The fixing protrusion is positioned at the edge of the board in a location that minimally interferes with the board's overall size reduction while maintaining the necessary circuit configuration space. This edge-positioned fixing mechanism allows the board to be compact without restricting circuit design flexibility in the remaining board area

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
