Solution Overview

Problem

The assembly of optical modules with high requirements for fineness of adjustment is cumbersome and costly due to the need for complex adjusting mechanisms, which increases the overall cost and complexity of the optical module.

Innovation Solution

The optical module employs two bearers with inclined planes and protruding portions that allow for precise adjustment of the light source and lens by simple rotational operations, eliminating the need for a complex adjusting mechanism and enabling high-fineness adjustments without increasing cost.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a complex adjusting mechanism (e.g., gear box) is provided to achieve high fineness of adjustment, then the manufacturing precision is improved, but the device complexity and cost are increased

Engineering Contradiction:
Improvefineness of adjustmentVSAvoidadjusting mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent employs an inclined plane with a curved surface instead of flat adjustment surfaces. The protruding portion engages with the inclined plane, and rotational movement along the curved surface converts rotational motion into precise linear displacement. This curvature enables high fineness of adjustment through simple rotation without requiring complex gear mechanisms, thus improving manufacturing precision while reducing device complexity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent changes the geometric parameters of the bearing surfaces by introducing an inclined plane with a specific angle and curvature radius. By adjusting these parameters, the system achieves high precision adjustment through rotational movement. The protruding portion's engagement with the inclined plane allows controlled displacement along the optical axis, transforming the adjustment mechanism from complex multi-component to a simple geometric parameter-based solution.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If multiple screws are provided on the bearer to adjust the position in multiple directions, then the ease of operation is improved, but the device complexity is increased

Engineering Contradiction:
Improveposition adjustment capabilityVSAvoidnumber of adjustment components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple adjustment functions into a single integrated structure. The first bearer incorporates both the inclined plane and the protruding portion (which may include multiple protruding portions for different directions) into one component. This allows position adjustment in multiple directions (X, Y, Z) to be achieved through rotation of a single bearer rather than using multiple independent screws, thereby maintaining ease of operation while reducing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The first bearer is designed as a multi-functional component that combines positioning, adjustment, and locking functions. The inclined plane provides the adjustment surface, while the protruding portion(s) enable engagement and rotational adjustment in multiple directions. This universal design allows a single component to perform what would traditionally require multiple separate adjustment mechanisms, reducing overall device complexity while maintaining operational ease.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An optical module includes a first bearer and a second bearer. The first bearer includes a first bearing portion and an inclined plane, the first bearing portion is configured to carry a first optical element, and the inclined plane is disposed on a peripheral edge of a first end surface of the first bearing portion. The second bearer includes a second bearing portion and a protruding portion, the second bearing portion is configured to carry a second optical element, a second end surface of the second bearing portion faces the first end surface, and the protruding portion extends from the second end surface to the first bearing portion and is configured to contact the inclined plane. When the protruding portion contacts the inclined plane, the inclined plane does not expose the protruding portion in a direction from the first bearing portion to the second bearing portion.
