Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical systems for illuminating objects through transparent or translucent media face challenges in preventing saturation of captured images due to direct reflection of illumination light, requiring large apparatuses or complex positional adjustments.
Innovation Solution
An optical control apparatus that includes a light source, a light collecting section, and an optical path control section, which changes the illumination direction by adjusting the position of a light-blocking element in a plane perpendicular to the optical axis, allowing for flexible illumination direction adjustment without moving the optical system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a diaphragm is moved in the optical axis direction to change illumination direction, then the illumination direction can be adjusted, but the apparatus size increases due to the need to secure movement area
Solution Approach 1:
The patent changes the dimension of diaphragm movement from the optical axis direction (depth) to a direction perpendicular to the optical axis (lateral movement). This allows the diaphragm to change illumination direction by moving laterally across the lens aperture, eliminating the need for deep mechanical travel and reducing apparatus volume while maintaining illumination direction control capability
2Object-affected harmful factors
If the position of optical system is changed to prevent direct reflection, then image saturation can be prevented, but the apparatus complexity increases due to positional adjustment mechanisms
Solution Approach 1:
The patent introduces a movable diaphragm that can dynamically adjust its position within the optical system to control light paths. By making the diaphragm movable in a plane perpendicular to the optical axis, the system can adaptively block direct reflection light without requiring complex positional adjustments of the entire optical system, thereby preventing image saturation while maintaining structural simplicity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the control of illumination direction without altering the optical system's position, minimizing apparatus size and preventing image saturation from direct reflections, while allowing for precise illumination adjustments.
Implementation Method 1
a light collecting section configured to collect light emitted from the light source and illuminate the light onto the object
Implementation Method 2
an optical path control section configured to be arranged between the light source and the light collecting section, and change an illumination direction of the light onto the object by changing a position of a portion through which the light passes in a plane perpendicular to an optical axis of the light
