Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic displays in public, outdoor environments face challenges such as damage from impacts, liquids, and vandalism, requiring a durable front panel that resists scratches, cracks, and penetration while maintaining high clarity and anti-reflective properties to withstand environmental and human-induced stressors.
Innovation Solution
A durable front glass panel comprising anti-reflective glass layers laminated together with an optical adhesive and sealed with VHB tape, which can crack without shattering and prevent penetration, using commercially available materials like Pilkington OptiView glass and Uvecol adhesive, ensuring high clarity and resistance to impacts and light interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single layer of glass is used for the display panel, then the manufacturing process is simple and cost is low, but the panel is susceptible to cracks and shattering upon impact
Solution Approach 1:
The display panel is divided into multiple glass layers (first display panel layer and second display panel layer) separated by a spacer structure. This segmentation allows each layer to absorb impact energy independently, preventing the panel from shattering while maintaining structural integrity.
Solution Approach 2:
The panel combines multiple glass layers with a spacer material (such as rubber or plastic) to create a composite structure. This composite construction provides both the strength needed to resist impacts and the flexibility to prevent shattering, resolving the contradiction between strength and complexity.
2Reliability
If the front panel is made thicker to prevent penetration and cracks, then durability and protection are improved, but the clarity and anti-reflective properties deteriorate
Solution Approach 1:
Instead of using a single thick glass layer, the patent segments the protective function across multiple thinner glass layers. Each layer maintains optimal thickness for clarity and anti-reflective properties, while the combined multi-layer structure provides the necessary protection against penetration and impacts.
Solution Approach 2:
A spacer layer is introduced as an intermediary between the glass layers. This spacer maintains appropriate spacing to optimize optical properties while providing additional protection, allowing the system to achieve both durability and clarity without requiring excessive glass thickness.
3Illumination intensity
If anti-reflective coating is applied to reduce light interference, then visibility in outdoor environments is improved, but the panel becomes more susceptible to surface damage and scratches
Solution Approach 1:
The patent creates a composite structure where multiple glass layers with anti-reflective coatings are combined with a spacer layer. This composite construction provides the anti-reflective properties needed for outdoor visibility while the multi-layer structure and spacer material work together to protect against scratches and surface damage.
Solution Approach 2:
The patent modifies the optical parameters of the glass layers by applying anti-reflective coatings while simultaneously adjusting the structural parameters by introducing spacer layers and optimizing glass thickness. This allows the system to achieve both anti-reflective properties and scratch resistance through coordinated parameter optimization.
4Strength
If multiple glass layers are laminated together to improve durability, then impact resistance is enhanced, but the manufacturing complexity and cost increase
Solution Approach 1:
The lamination process is segmented into discrete steps where pre-cut glass layers and spacers are assembled in a controlled sequence. This segmentation simplifies the manufacturing process by breaking down the complex lamination task into manageable stages with clear specifications for each component.
Solution Approach 2:
The patent optimizes manufacturing parameters by specifying precise thicknesses for glass layers and spacer materials, as well as defined lamination conditions. These parameter specifications standardize the manufacturing process, making it more efficient and cost-effective while maintaining the enhanced impact resistance provided by the multi-layer structure.
