Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large sensing area is used to collect optical signals, then signal collection efficiency is improved, but device size increases
Solution Approach 1:
A magnetic field is introduced as an intermediary to redirect optical signals toward the sensing region. The magnetic field acts as a mediator that changes the propagation direction of light without requiring the sensor itself to be large, thereby maintaining signal collection efficiency while reducing device area.
Solution Approach 2:
The optical path parameters are changed by applying a magnetic field that alters the direction of light propagation. This parameter change allows optical signals to be redirected into a compact sensing region, achieving efficient signal collection within a smaller area.
2Area of stationary object
If the sensing area is reduced to minimize device size, then device miniaturization is achieved, but optical signal collection capability deteriorates
Solution Approach 1:
The magnetic field serves as a mediator that compensates for the reduced sensing area by redirecting optical signals into the compact sensor. This allows the system to maintain signal collection capability despite the smaller sensing region.
Solution Approach 2:
The solution moves the problem from the spatial dimension to the field dimension by using a magnetic field to control light direction. This dimensional shift allows compact sensor design while maintaining optical signal collection through field-based manipulation rather than area-based collection.
3Area of stationary object
If a signal path modulation component is added to control optical signal direction, then device size is reduced, but device complexity increases
Solution Approach 1:
The magnetic field generation component serves multiple functions: it generates the magnetic field for signal redirection, acts as a signal path modulator, and enables compact device design. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.
