Optical Actuator Corner Disposing Areas Reduce Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical actuators are large in size, causing structural interference with projection lenses having partial focal lengths, particularly those with short back focus distances, limiting their applicability.
Innovation Solution
The optical actuator design includes a base with a mounting surface, a light-transmitting plate, a frame, suspension members, and actuation members. The suspension and actuation members are concentrated on disposing areas at the corners of the base, reducing the mounting surface area and the overall volume of the optical actuator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing optical actuators are used, then the pixel quality can be improved through vibration, but the large size causes structural interference with projection lenses having short back focus distances
Solution Approach 1:
The patent concentrates the suspension members and actuation members on disposing areas at the corners of the base, utilizing corner space that was previously underutilized. This dimensional reorganization reduces the mounting surface area occupied by these components, thereby reducing the overall volume of the optical actuator without compromising its vibration function for pixel quality improvement.
Solution Approach 2:
The patent segments the mounting surface into specific disposing areas located at the corners of the base, separating the suspension and actuation members from the central optical path area. This segmentation allows for more efficient space utilization and reduces the overall footprint of the optical actuator, resolving the contradiction between maintaining vibration functionality and reducing size.
2Adaptability or versatility
If the optical actuator volume is reduced, then applicability with projection lenses of various focal lengths increases, but the structural complexity of concentrating components on corner disposing areas increases
Solution Approach 1:
The patent designs the frame to retreat inwardly relative to the mounting surface, creating corner disposing areas that serve dual purposes: they provide mounting locations for suspension and actuation members while also serving as structural support elements. This multi-functional design reduces overall component count and structural complexity despite the concentrated layout.
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 design effectively reduces the volume occupied by the optical actuator, increasing its applicability with projection lenses of various focal lengths without causing structural interference.
Implementation Method 1
The suspension members are respectively located on the disposing areas and connected between the base and the frame
Implementation Method 2
The light-transmitting plate is located above the mounting surface... the light is then transmitted to the projection lens through the optical actuator

AI summary
An optical actuator includes a base, a light-transmitting plate, a frame, a plurality of suspension members, and a plurality of actuation members. The base has a mounting surface. The light-transmitting plate is located above the mounting surface. The frame frames an outer edge of the light-transmitting plate. The frame retreats inwardly relative to the mounting surface, so that the mounting surface has a plurality of disposing areas relative to the frame. The suspension members are respectively located on the disposing areas and connected between the base and the frame. The actuation members are respectively located on the disposing area and configured to drive the frame to reciprocate relative to the mounting surface.
