Solution Overview

Problem

The fixed aperture size in electronic devices limits the photographing effect and application scenarios of lens modules, resulting in a poor user experience, as it cannot adapt to different lighting conditions or photography requirements.

Innovation Solution

A lens module with a blade assembly that includes two rotatably connected blades with arc-shaped notches, driven by a magnetic induction-based driving assembly, allowing for the switching between multiple apertures of different sizes to match various application scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the aperture size is fixed, then the device structure is simple, but the photographing effect and application scenarios are limited

Engineering Contradiction:
Improvephotography effectVSAvoidaperture structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The aperture structure is transformed from a fixed state to a dynamic, adjustable state. The blade assembly can rotate between a first position and a second position, enabling the aperture to switch between a first aperture and a second aperture with different sizes, thus adapting to different photography requirements while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The aperture is divided into multiple segments (first aperture and second aperture) with different sizes, each suitable for specific photography scenarios. The blade assembly acts as a separator that can be positioned to reveal either the first aperture or the second aperture, allowing the system to offer multiple aperture options without requiring a completely complex variable aperture mechanism.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the aperture size is fixed, then the device structure is simple, but the application scenarios are limited

Engineering Contradiction:
Improveapplication scenariosVSAvoidaperture structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The aperture structure is transformed from a fixed state to a dynamic, adjustable state. The blade assembly can rotate between a first position and a second position, enabling the aperture to switch between a first aperture and a second aperture with different sizes, thus adapting to different photography requirements while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The aperture system is designed to serve multiple functions and application scenarios through a unified structure. By providing both a first aperture and a second aperture that can be selectively used, the system can handle various photography conditions (such as different lighting environments, depth of field requirements) without requiring separate dedicated apertures for each scenario.

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

3Ease of operation

If the aperture is fixed, then the manufacturing is simple, but the user experience is poor

Engineering Contradiction:

Solution Approach 2:

The aperture system automatically adapts to different photography scenarios through the rotation of the blade assembly. The system can switch between the first aperture and the second aperture based on the required photography conditions, providing users with appropriate aperture settings without requiring manual intervention or complex control mechanisms.
