Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ultra-thin display devices with large screens face challenges in ensuring structural rigidity, flatness of the frame, and durability of the coupling structure between the composite panel and the fastening member.
Innovation Solution
A display device configuration that includes a display panel, a composite panel with a core of fibers sandwiched between front and rear skins, and a fastening member with a shaft body and a head that is pushed into one of the skins, enhancing the structural integrity and coupling stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display device is made ultra-thin with a large screen, then the brightness and viewing angle are improved and the device becomes thinner, but the structural rigidity deteriorates
Solution Approach 1:
The patent employs a composite panel comprising a front skin, rear skin, and core material with fibers arranged in a specific pattern. This composite structure provides enhanced structural rigidity while maintaining an ultra-thin profile, directly resolving the contradiction between thinness and structural strength in large-screen display devices
2Shape
If the display device is made ultra-thin with a large screen, then the device becomes thinner, but the flatness of the frame deteriorates
Solution Approach 1:
The composite panel with fiber-reinforced core material provides internal structural support that maintains frame flatness while enabling an ultra-thin overall design. The fiber arrangement within the core creates a rigid yet thin structure that prevents frame warping
Solution Approach 2:
The patent implements local reinforcement through the composite panel structure, where the core material with specific fiber orientation provides targeted support to maintain frame flatness in critical areas while keeping the overall device thickness minimal
3Strength
If a fastening member is coupled to the composite panel, then the structural integrity is improved, but the durability of the coupling structure deteriorates due to stress concentration
Solution Approach 1:
The patent creates localized reinforcement zones around fastening holes by arranging fibers in specific patterns (radial, circumferential, or spiral orientations) in the core material. This local fiber arrangement distributes stress concentration around the fastening members, improving coupling durability while maintaining overall structural integrity
Solution Approach 2:
The composite panel's fiber-reinforced core material provides enhanced toughness and stress distribution capabilities around coupling points, preventing crack propagation and improving the long-term durability of the coupling structure between the composite panel and fastening members

AI summary
A display device is disclosed. The display device includes a display panel, a composite panel coupled to the display panel, and a fastening member coupled to the composite panel. The composite panel includes a front skin defining a front surface of the composite panel, a rear skin defining a rear surface of the composite panel and opposed to the front skin, a core positioned between the front skin and the rear skin and including fibers, and a fastening hole formed through the front skin, the rear skin, and the core. The fastening member includes a shaft body disposed in the fastening hole, and a head connected to the shaft body and pushed into one of the front skin or the rear skin. One of the front skin or the rear skin is in contact with a lateral surface of the head.
