Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the variable wavelength optical filter and detector are disposed on a line along the optical axis as separate bodies, then the optical path is simplified, but the number of manufacturing steps increases and productivity decreases
Solution Approach 1:
The patent merges the variable wavelength optical filter and detector into a single integrated package structure. Both components are disposed on the same side of the package relative to the reflection part, allowing them to be manufactured and assembled as a unified unit rather than separate components, thereby reducing manufacturing steps and improving productivity
2Ease of manufacture
If the variable wavelength optical filter and detector are treated as separate bodies, then individual component optimization is easier, but assembly complexity and manufacturing time increase
Solution Approach 1:
By integrating the filter and detector into a single package with shared manufacturing processes, the patent eliminates the time loss associated with separate assembly operations. The components are designed to be manufactured together using the same process steps, reducing overall manufacturing time while maintaining ease of manufacture through standardized integration
3Productivity
If the filter and detector are integrated in the package, then manufacturing steps are reduced, but alignment precision requirements increase
Solution Approach 1:
The reflection part within the package serves as a self-aligning reference structure. By positioning both the filter and detector relative to this common reference element, the system achieves precise alignment automatically during manufacturing without requiring additional alignment operations, thereby maintaining high manufacturing precision while improving productivity

AI summary
A variable wavelength optical filter module according to the present invention includes a package, a variable wavelength optical filter, and a detector. The package includes a reflection part (reflecting faces) in the inside of the package. The variable wavelength optical filter is disposed in the inside of the package and includes a first reflecting plate and a second reflecting plate facing each other, with a clearance between the first reflecting plate and the second reflecting plate being variable. The detector is disposed in the inside of the package and detects a ray of light having passed through the variable wavelength optical filter. Then, the variable wavelength optical filter and the detector are disposed on the opposite side to the reflection part (reflecting faces). The ray of the light incident into the inside of the package via the variable wavelength optical filter enters the detector via the reflection part (reflecting faces).
