Solution Overview

Problem

Liquid crystal displays rely heavily on the performance of their backlight units, which can be prone to external shocks and require additional fixing components, complicating manufacturing and increasing costs.

Innovation Solution

A display device design that incorporates a fixing member made of synthetic resin between the display part and the frame, enhancing coupling force and providing shock protection, while simplifying the manufacturing process by eliminating the need for additional fixing units like adhesive tapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional fixing components are used to secure the backlight assembly, then the reliability of the display device is improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The frame structure is merged with the fixing function by forming a receiving groove directly in the frame, eliminating the need for separate fixing components. The backlight assembly is received and fixed within this integrated groove, combining structural support and fixation into a single component system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The frame serves multiple functions simultaneously: it provides structural support, defines the display device boundaries, and acts as a fixing mechanism for the backlight assembly through its receiving groove. This multi-functionality reduces the number of separate components needed.

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

2Reliability

If additional fixing components are used to secure the backlight assembly, then the reliability of the display device is improved, but the manufacturing cost increases

Engineering Contradiction:
ImprovereliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The fixing function is merged into the frame structure itself, eliminating the need for separate fixing components. This reduces the total number of parts that need to be manufactured, purchased, and assembled, thereby reducing manufacturing cost while maintaining reliable fixation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The separate fixing components are extracted from the system and their functionality is integrated into the frame. By removing unnecessary separate parts and consolidating functions into the frame, the manufacturing process is simplified and costs are reduced.

Inventive Principle:
Principle #2Taking out (Extraction)

3Strength

If a resin-based fixing member is used between the display part and the frame, then the coupling force is enhanced and shock protection is provided, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvecoupling forceVSAvoidmanufacturing process complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

A resin-based fixing member is introduced as an intermediary between the display part and the frame. This resin member provides enhanced coupling force and shock absorption, acting as a compliant connector that maintains strong bonding while accommodating minor dimensional variations and providing vibration damping.

Inventive Principle:
Principle #24Intermediary (Mediator)
