Rib Structure Impact Absorption for Display Panel Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with LCD panels are inadequate in protecting the panels from impact damage, as current protection methods either fail to absorb impact forces effectively or allow direct transmission of forces to the panel, leading to breakage.
Innovation Solution
A display device design featuring a housing, bezel, and a rib structure that maintains a gap between the bezel and the display panel, allowing impact forces to be absorbed and redirected away from the panel, with optional padding to prevent dust entry and using materials like plastic or magnesium for the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pad is disposed between the display panel and the bezel for protection, then the display panel is protected during normal drops, but the impact force still transmits directly to the display panel when impacted excessively
Solution Approach 1:
A rib structure is introduced as an intermediary element between the bezel and the display panel. This rib structure absorbs and disperses impact forces through its geometric configuration, preventing direct transmission of force to the display panel while maintaining the protective function.
Solution Approach 2:
The rib structure is pre-configured in the bezel design to provide cushioning before impact occurs. The ribs are positioned and dimensioned to deform or absorb energy during impact, creating a protective buffer that activates automatically upon contact.
2Reliability
If see-through glass is disposed on the display panel for further protection, then the display panel receives additional protection, but the glass must be in tight contact with the display panel which conducts impact force to the panel
Solution Approach 1:
The rib structure serves as a mediator between the protective glass and the display panel. By positioning the ribs between the glass and panel, impact forces are absorbed and dispersed by the rib geometry rather than being transmitted directly to the panel, while the glass remains in tight contact for optical purposes.
Solution Approach 2:
The rib structure creates localized zones of impact absorption at specific positions between the bezel and display panel. This allows the protective glass to maintain tight contact with the panel for optical quality while the ribs provide localized cushioning at critical impact points.
3Shape
If the bezel is disposed close to the display panel for a compact design, then the device achieves a sleek appearance, but impact force is directly transmitted to the display panel
Solution Approach 1:
The bezel is segmented with rib structures that create a multi-level configuration. This segmentation allows the bezel to maintain a compact overall appearance while incorporating internal geometric features that provide impact absorption without increasing the external dimensions.
Solution Approach 2:
The rib structure utilizes the depth dimension within the bezel to create impact absorption zones. By adding vertical relief features (ridges and grooves) within the existing bezel thickness, protection is achieved without increasing the lateral dimensions or compromising the compact design.

AI summary
A fixing device includes a housing, a bezel, and a rib structure. The housing has a first side. The bezel is connected to the housing for covering the flat structure with the housing. The bezel has a second side and a third side. The rib structure is disposed outside the flat structure and is located between the first side of the housing and the second side of the bezel for keeping a gap between the second side of the bezel and the flat structure.
