Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixing element is assembled on the housing to secure the optical lens, then the optical lens is firmly fixed, but the position of the optical lens cannot be finely adjusted

Engineering Contradiction:
Improvefixing stabilityVSAvoidadjusting convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The fixing structure is divided into a fixed portion (outer frame) and a movable portion (inner frame with optical lens), connected through the adjusting mechanism. This segmentation allows the optical lens to be firmly held while enabling precise position adjustment through the adjusting element.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing structure transitions from a completely static state to a dynamically adjustable state. The adjusting element allows the optical lens to be positioned precisely during assembly and then locked in place, providing both adjustability and stability as needed.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the optical lens position is adjusted manually without a precise adjusting mechanism, then the adjusting process is simple, but the positioning precision is insufficient

Engineering Contradiction:
Improveadjusting simplicityVSAvoidpositioning precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The manual adjustment process is enhanced by introducing a mechanical adjusting mechanism (adjusting element with rolling elements) that converts simple rotational motion into precise linear displacement of the optical lens, achieving high positioning precision while maintaining operational simplicity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The adjusting element changes the position parameter of the optical lens precisely by converting rotational motion into linear motion through the rolling elements, allowing fine control over the lens position without complex adjustment procedures.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If the optical lens position is adjusted after assembly, then the optical effects can be optimized, but the processing time increases

Engineering Contradiction:
Improveoptical effect optimizationVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The adjusting mechanism is pre-installed on the housing before the optical lens is permanently fixed. This preliminary setup allows for quick position adjustments during assembly without requiring disassembly or complex rework, thereby optimizing optical effects while minimizing additional processing time.

Inventive Principle:
Principle #10Preliminary action
