Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal layer is used in the millimeter wave reflector, then reflection characteristics are improved, but the metal layer corrodes when in contact with aqueous adhesive
Solution Approach 1:
An adhesive layer is introduced as an intermediary between the aqueous adhesive and the metal layer. This adhesive layer acts as a protective barrier that prevents direct contact between the aqueous adhesive and the metal layer, thereby preventing corrosion while maintaining the reflection characteristics of the metal layer.
Solution Approach 2:
The adhesive layer is applied beforehand to protect the metal layer from corrosion. By establishing this protective barrier before the aqueous adhesive comes into contact with the metal layer, the design preemptively prevents the harmful corrosion effect while preserving the reflective function.
2Duration of action of stationary object
If a protective layer is added to protect metal patterns, then durability is improved, but device complexity increases
Solution Approach 1:
The protective layer is merged with the adhesive layer, combining the functions of adhesion and protection into a single integrated layer. This reduces the number of separate components and simplifies the overall structure while still providing the necessary protection for the metal patterns.
Solution Approach 2:
The adhesive layer is designed to serve multiple functions: it provides adhesion between layers and simultaneously acts as a protective barrier against corrosion. This multi-functionality reduces the need for additional separate protective layers, thereby simplifying the overall structure.
3Object-affected harmful factors
If aqueous adhesive is used for installation, then health safety is improved, but bonding performance deteriorates due to metal layer corrosion
Solution Approach 1:
The adhesive layer serves as an intermediary that allows the use of environmentally friendly aqueous adhesive while preventing it from directly contacting and corroding the metal layer. This maintains both the health safety benefits of aqueous adhesive and the bonding performance required for secure installation.
Solution Approach 2:
By applying the adhesive layer beforehand as a protective barrier, the system enables the use of aqueous adhesive without compromising bonding performance. The protective barrier prevents corrosion that would otherwise weaken the bond, thus maintaining both health safety and bonding strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The material maintains good reflection characteristics and appearance over time, even when installed outdoors, and functions well with aqueous adhesives.
Implementation Method 1
a reflector that reflects millimeter-wave radio waves
Implementation Method 2
protect the metal patterns for a long period of time to prevent them from deteriorating and their reflective characteristics from significantly decreasing or disappearing
Implementation Method 3
an aqueous adhesive is generally used for reasons such as preventing sick building syndrome
Implementation Method 4
Since the reflected waves undergo mutual interference, the millimeter wave is reflected with a phase different from that at the time of incidence
