Solution Overview

Problem

Existing binocular cameras have limited monitoring fields of view due to fixed-focus and zoom lenses that can only rotate in a single direction, restricting their ability to fully track and capture details within a panoramic scope.

Innovation Solution

A double chamber camera design featuring a first and second support that can rotate independently, allowing a zoom lens to adjust its field of view in two directions, combined with fixed-focus lenses for expanded monitoring capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single-direction rotation mechanism is used for the zoom lens, then the device complexity is reduced, but the monitoring field of view is limited and cannot fully track the panoramic scope

Engineering Contradiction:
Improverotation mechanism complexityVSAvoidmonitoring field of view
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The rotation mechanism is segmented into two independent single-direction rotation mechanisms: a first rotation mechanism for horizontal rotation and a second rotation mechanism for vertical rotation. Each mechanism independently controls rotation in one direction, maintaining simplicity while collectively enabling two-dimensional panoramic tracking capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from single-direction (one-dimensional) rotation to two-directional (two-dimensional) rotation by adding another rotation dimension. The first support rotates horizontally while the second support rotates vertically, expanding the monitoring field of view from a single arc to a comprehensive panoramic scope.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If the zoom lens is fixed in a single position, then the device complexity is minimized, but the field of view cannot be adjusted to match the fixed focus lens for comprehensive monitoring

Engineering Contradiction:
Improvelens positioning system complexityVSAvoidfield of view adjustment capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The zoom lens positioning system transitions from a static fixed position to a dynamic adjustable position through the two-support rotation mechanism. The first support and second support enable the zoom lens to dynamically adjust its viewing angle in both horizontal and vertical directions, allowing the field of view to be flexibly matched with the fixed focus lens for comprehensive panoramic monitoring.

Inventive Principle:
Principle #15Dynamics

AI summary

The present disclosure provides a double chamber camera. The double chamber camera may include: a housing having an upper chamber and a lower chamber; and an upper chamber assembly arranged in the upper chamber, and a lower chamber assembly arranged in the lower chamber. The upper chamber assembly may include a first monitoring lens and a first transmission module. The first monitoring lens may be a zoom lens. The first transmission module may include a first support and a second support rotatably matched with the first support, a first driving unit configured to drive the first support to rotate along a first direction, and a second driving unit configured to driving the second support to rotate along a second direction. The first monitoring lens may be fixed on the first support or the second support.
