Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing image acquisition devices face issues with lens cleanliness during angle adjustment, leading to maintenance costs and inconvenient angle adjustments.

Innovation Solution

An image acquisition device with a rotating portion and a knob portion arranged laterally to the camera, allowing users to adjust the camera angle without direct contact, reducing contamination and simplifying the adjustment process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the camera is made rotatable to adjust photographing angle, then the adaptability of the device is improved, but the camera lens becomes easily contaminated

Engineering Contradiction:

Improvephotographing angle adjustmentVSAvoidlens contamination

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The device is segmented into a rotatable portion containing the camera and a fixed portion containing the knob. By separating the rotation function from the camera body, users can adjust angles by rotating the portion rather than touching the camera directly, thus preventing lens contamination while maintaining angle adjustment capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The rotatable portion acts as an intermediary between the user's rotation action and the camera. Users rotate the outer portion which carries the camera, rather than directly touching the camera itself. This intermediary structure transfers the rotational motion while isolating the camera from direct user contact, preventing contamination.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If users directly rotate the camera to adjust angle, then the operation is simple, but the camera gets dirty requiring maintenance

Engineering Contradiction:

Improveangle adjustment convenienceVSAvoidmaintenance workload

Core Design Contradiction:

Ease of operationVSEase of repair

Solution Approach 1:

By dividing the device into a rotatable portion and a fixed camera housing, the design allows users to rotate the outer portion easily while the camera remains protected. This segmentation maintains operational simplicity while eliminating the need to handle the camera directly, reducing maintenance requirements.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If the camera is made rotatable for angle adjustment, then the versatility is improved, but the maintenance cost increases due to cleaning requirements

Engineering Contradiction:

Improveimage acquisition angleVSAvoidmaintenance cost

Core Design Contradiction:

Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The rotatable portion serves as a mediator that allows angle adjustment without direct contact with the camera. Users interact with the outer rotatable structure rather than the camera itself, preventing contamination and eliminating cleaning costs while preserving full angle adjustment versatility.

Inventive Principle:

Principle #24Intermediary (Mediator)
