Solution Overview
Problem
The optical scanning apparatus disclosed in existing technologies experiences a change in the outgoing angle of the light beam when inclined relative to a horizontal surface, leading to instability in beam orientation.
Innovation Solution
An optical scanning apparatus with a scanning mirror and attitude detector integrated on a substrate, where a reflection member's inclination is adjusted based on the attitude angle detected by the attitude detector to maintain a stable outgoing angle of the light beam, regardless of the apparatus's inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the optical scanning apparatus is inclined with respect to the horizontal surface, then the apparatus can be installed in various orientations, but the outgoing angle of the light beam with respect to the horizontal surface changes
Solution Approach 1:
The attitude detector continuously monitors the inclination angle of the substrate and feeds this information back to the controller. The controller then adjusts the reflection member's inclination accordingly to compensate for changes in beam output angle, ensuring stable beam orientation regardless of apparatus inclination.
Solution Approach 2:
The system dynamically changes the inclination parameter of the reflection member based on the detected attitude angle of the substrate. By adjusting the reflection member's angle in response to substrate inclination, the system maintains constant beam outgoing angle despite changes in apparatus orientation.
2Reliability
If the reflection member's inclination is adjusted to maintain beam angle stability, then the outgoing angle remains stable, but the device complexity increases
Solution Approach 1:
The scanning mirror and attitude detector are integrated on the same substrate, combining multiple functions into a single unit. This integration reduces the number of separate components and simplifies the overall structure while maintaining the ability to detect and compensate for inclination changes.
Solution Approach 2:
The substrate serves multiple functions: it supports the scanning mirror for beam generation and the attitude detector for inclination measurement. This multi-functionality reduces the number of separate structural elements needed, thereby reducing device complexity while achieving beam angle stabilization.
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
This configuration ensures the light beam maintains a stable angle relative to the horizontal surface, even when the apparatus is inclined, due to the integrated attitude detection and adjustment mechanism, enhancing the apparatus's stability and accuracy.

AI summary
An optical scanning apparatus includes a light source, a substrate, a reflection member, a drive unit, and a controller. A scanning mirror and an attitude detector are integrated with substrate. An attitude detector outputs a first signal according to an attitude angle of substrate. A reflection member reflects a light beam reflected by scanning mirror. A drive unit can adjust an inclination of reflection member with respect to a main surface of substrate. A controller controls drive unit based on first signal. For this reason, an outgoing angle of light beam from optical scanning apparatus with respect to a horizontal surface can stably be maintained regardless of the inclination of optical scanning apparatus with respect to horizontal surface.
