Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent glass substrate with anti-reflective coating is used to reduce glare and reflection, then the visual clarity and display quality are improved, but the durability and protection against physical damage are worsened
Solution Approach 1:
The patent applies composite materials by combining multiple layers including glass substrate, anti-reflective coating, and adhesive layers to create a multi-functional protective assembly that simultaneously provides optical clarity and physical durability
Solution Approach 2:
The patent merges multiple functions into a single integrated assembly by combining the anti-reflective coating with the glass substrate through adhesive bonding, creating a unified structure that provides both optical performance and mechanical strength
2Length of moving object
If the glass substrate thickness is reduced to less than or equal to 1.1 millimeters to make the display thinner, then the overall device profile is improved, but the structural strength and impact resistance are worsened
Solution Approach 1:
The patent uses composite materials by creating a multi-layer assembly with glass substrate, anti-reflective coating, and adhesive layers that collectively provide enhanced structural strength despite the reduced glass thickness
Solution Approach 2:
The patent applies the nested doll principle by nesting multiple functional layers (anti-reflective coating, adhesive layers) within and around the thin glass substrate, creating a compact multi-layer structure that compensates for the reduced individual layer thickness
3Adaptability or versatility
If multiple coatings are added to the glass substrate for electromagnetic interference shielding and hydrophobic properties, then the functionality and ease of cleaning are improved, but the manufacturing complexity is worsened
Solution Approach 1:
The patent merges multiple functional coatings (anti-reflective, electromagnetic interference shielding, hydrophobic) into an integrated multi-layer assembly that is applied to the glass substrate in a systematic manufacturing process
Solution Approach 2:
The patent applies universality by designing a multi-layer assembly that simultaneously provides multiple functions including anti-reflection, electromagnetic interference shielding, hydrophobic properties, and mechanical bonding in a single integrated structure
