Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If optical waveguides are used as hazard parameter conductors for low-loss transmission of electromagnetic radiation, then transmission loss is reduced, but the waveguides become sensitive to mechanical stress such as bending or vibration which can cause lasting damage to the glass-fiber bundles
Solution Approach 1:
The hazard parameter conductor is divided into modular segments that can be connected together. Each segment is rigid and resistant to bending, while the modular design allows flexible installation paths. The segments are connected through specialized coupling mechanisms that maintain optical alignment while accommodating mechanical stresses at connection points.
Solution Approach 2:
The hazard parameter conductor uses composite structures combining rigid materials for mechanical strength with optical-quality materials for low-loss transmission. The outer protective layer provides mechanical protection against bending and vibration, while the inner core maintains optical properties for efficient electromagnetic radiation transmission.
2Strength
If the optical waveguide is screwed into the wall holder during mounting, then secure fixation is achieved, but the waveguide must rotate several times about its longitudinal axis which increases the likelihood of damage to the optical waveguide and its glass-fiber bundle
Solution Approach 1:
The mounting system is divided into separate components: a wall holder, an adapter, and the optical waveguide segment. The adapter acts as an intermediary that attaches to the wall holder without requiring rotation of the fragile waveguide. The waveguide is connected to the adapter through a non-rotating coupling mechanism that maintains alignment during installation.
Solution Approach 2:
An adapter component is introduced between the wall holder and the optical waveguide. This adapter provides the rotational interface with the wall holder while presenting a non-rotating connection point to the waveguide. The adapter absorbs the rotational movement during mounting, protecting the waveguide from mechanical stress while achieving secure wall fixation.
3Reliability
If sensors are kept away from high temperature areas, then sensor protection is improved, but the transmission of hazard parameters such as temperature or heat intensity to the sensor is reduced
Solution Approach 1:
The patent replaces thermal conduction through physical contact with optical transmission through the hazard parameter conductor. Electromagnetic radiation (optical signals) carries temperature and heat information from the high-temperature measurement point to the protected sensor location. This optical substitution allows the sensor to remain in a cool, protected environment while still detecting high-temperature conditions accurately.
Solution Approach 2:
The hazard parameter conductor acts as an intermediary that transmits temperature and heat information from the hot measurement zone to the cool sensor zone. The conductor is positioned in the high-temperature area but is designed to withstand these conditions, while the sensor remains protected in a lower-temperature environment. The optical signals travel through the conductor without being affected by the temperature gradient.
