Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional optical sensors are packaged with a fixed structure, then manufacturing process is simplified, but adaptability to different applications is reduced
Solution Approach 1:
The optical sensor is divided into two parts: a base sensor unit and detachable film members. The film members can be attached or detached from the base sensor, allowing different optical functions to be added without changing the base sensor structure. This segmentation enables both simplified manufacturing of the base unit and high adaptability through interchangeable film members.
Solution Approach 2:
The base optical sensor is designed as a universal platform that can work with multiple types of film members. Each film member provides different optical functions (e.g., wavelength selection, polarization control), and the same base sensor can be configured for different applications by simply changing the film member, achieving multi-functionality without multiple sensor designs.
2Adaptability or versatility
If multiple different sensor designs are created to meet different application demands, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
Instead of manufacturing multiple different sensor designs, the invention creates one universal base sensor that can be adapted to different applications through interchangeable film members. This significantly reduces manufacturing complexity and cost while maintaining the ability to meet diverse application demands.
Solution Approach 2:
The film members can be detached and replaced based on application needs. When an application changes, the old film member is discarded and a new one is attached to the same base sensor, avoiding the need to discard or remanufacture the entire sensor unit. This recovers the value of the base sensor across multiple applications.
3Manufacturing precision
If optical elements are integrated into the sensor during packaging, then optical performance is optimized, but post-packaging design flexibility is reduced
Solution Approach 1:
The optical system is segmented into fixed base sensor components and detachable film member components. The film members contain the optical elements and can be attached or detached after packaging, allowing optical design changes without opening or repackaging the sensor. This maintains manufacturing precision while enabling post-packaging flexibility.
Solution Approach 2:
The optical configuration is made dynamic through the ability to attach and detach different film members after packaging. Instead of a static, fixed optical design, the system can be reconfigured for different applications by simply changing the film member, providing adaptability without compromising the precision of each individual optical design.
