Slim Display Structure With Glass Light Guide And Edge Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to achieve a thin profile due to structural limitations, particularly in the integration of light guide members and holding components.
Innovation Solution
The display device employs a holding member along the outer edge of the support substrate to hold the light guide member, using a glass material for the light guide plate and a metal support substrate, with a reduced thickness and enhanced rigidity, and incorporates a bezel design that minimizes bezel dimensions through magnetic engagement and screw fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a conventional holding member structure is used to hold the light guide member, then the structural integrity is maintained, but the thickness of the display device increases
Solution Approach 1:
The holding member transitions from a three-dimensional block structure to a two-dimensional flat plate structure. The light guide member is held by joining to the flat plate surface rather than being clamped between thickness-direction surfaces, effectively reducing the thickness dimension while maintaining holding functionality through in-plane structural design
Solution Approach 2:
The light guide member holding function is extracted from the traditional thickness-direction clamping structure and repositioned to the outer edge region of the support substrate. The holding member is strategically placed only where needed at the periphery, removing unnecessary material from the thickness direction while preserving structural integrity through optimized spatial distribution
2Length of moving object
If the holding member thickness is reduced to achieve a thin profile, then the display device thickness decreases, but the rigidity of the holding member may be compromised
Solution Approach 1:
The holding member is constructed from composite materials combining resin base material with fiber reinforcements (glass fibers, carbon fibers, or aramid fibers). This composite structure provides high rigidity and strength-to-weight ratio, enabling the holding member to maintain structural stability with reduced thickness. The fiber reinforcement compensates for the reduced thickness by providing enhanced mechanical properties
Solution Approach 2:
The holding member features localized thickness variation and material distribution. The outer edge region where the light guide member is held has optimized thickness and material composition specifically tailored for structural support, while other regions may have different characteristics. This local optimization ensures rigidity where needed without unnecessarily increasing overall thickness
3Length of moving object
If the bezel dimensions are minimized for a slim profile, then the aesthetic appeal and thinness are improved, but the structural support and thermal management capabilities are reduced
Solution Approach 1:
The bezel incorporates magnetic engagement mechanisms that replace or supplement traditional mechanical screw fixation. Magnetic forces provide structural support and component retention without requiring large mechanical fasteners, enabling minimized bezel dimensions while maintaining reliable structural support. The magnetic system offers both mechanical holding and thermal conduction pathways
Solution Approach 2:
The bezel structure is designed to perform multiple functions simultaneously: structural support, thermal management, and component fixation. By integrating these functions into a single minimized bezel structure, the design achieves slim profile while maintaining reliability. The bezel acts as both a mechanical support frame and a thermal conduction pathway, eliminating the need for separate dedicated components
