Solution Overview
Problem
Display devices face challenges in minimizing heat concentration and maintaining a lightweight structure while ensuring the structural integrity and heat dissipation of the display panel.
Innovation Solution
A display device design featuring an intermediate panel with a honeycomb or wave-shaped corrugated structure, attached to the rear surface of the display panel via a bracket, which includes guide grooves and penetration parts for flexible printed circuit films, and a rear cover for heat dissipation and protection, along with a side cover for external appearance and support, facilitating assembly and insulating functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid support structure is added to prevent deformation and breakage of the display panel, then structural integrity is improved, but weight increases
Solution Approach 1:
The support structure is divided into a modular bracket system with multiple combining parts (first combining part attached to intermediate panel, second combining part attached to display panel) rather than a single rigid frame. This segmentation allows the support function to be distributed across multiple lightweight components that can be optimally positioned.
Solution Approach 2:
The bracket is constructed using composite material structure combining metal components (for strength at critical joints) with plastic or polymer components (for lightweight connections). The intermediate panel itself uses a composite structure with a rigid outer layer and a honeycomb or corrugated core, providing high strength-to-weight ratio.
2Temperature
If heat dissipation structures are added to minimize heat concentration, then thermal management is improved, but device complexity increases
Solution Approach 1:
The bracket serves multiple functions simultaneously: it provides structural support to prevent display panel deformation, acts as a heat dissipation pathway by thermally coupling the display panel to the intermediate panel, and enables assembly through its combining parts. This multi-functionality eliminates the need for separate support and thermal management components.
Solution Approach 2:
The intermediate panel acts as a thermal intermediary between the display panel and the rear cover. It receives heat from the display panel through the bracket's thermal conduction, stores it temporarily in its honeycomb structure, and dissipates it to the surrounding environment, preventing direct heat concentration on the display panel.
3Strength
If an intermediate panel is added to support the display panel and dissipate heat, then structural integrity and heat dissipation are improved, but device complexity increases
Solution Approach 1:
The bracket merges the support function and heat dissipation function into a single integrated component structure. The first combining part and second combining part are connected through the intermediate panel to form a unified support-thermal management system, reducing the need for separate support frames and heat sinks.
Solution Approach 2:
The intermediate panel uses localized honeycomb or corrugated structure only in regions where maximum strength-to-weight ratio is needed (such as around the display panel edges), while other areas use simpler flat panel construction. This localized application of complex structure minimizes overall device complexity while maintaining necessary structural integrity.
