Problem

Conventional security camera systems suffer from inadequate positional accuracy and space inefficiency due to the large size of the camera and infrared lamp support structures, leading to suboptimal image quality at night.

Innovation Solution

A camera module assembly with a support bracket system that includes bent sectional support pins and holes, a main bracket with cavity portions, and a light projecting portion with parallel optical axes, ensuring precise alignment and reduced space usage through a compact design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the support portions for camera and infrared lamp are made large, then the structural stability is improved, but the space efficiency deteriorates and positional accuracy cannot be sufficiently secured

Engineering Contradiction:

Improvestructural stabilityVSAvoidspace efficiency

Core Design Contradiction:

Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The support bracket is divided into multiple functional portions: a camera support portion with support pins for the camera module, a lamp support portion with support holes for the infrared lamp, and a connection portion for mounting. This segmentation allows each portion to be optimized independently, achieving stable support with reduced overall space occupation compared to a monolithic support structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support bracket utilizes three-dimensional spatial arrangement by extending in multiple directions from the connection portion. The camera support portion and lamp support portion are positioned in different spatial dimensions, allowing both components to be stably supported while maintaining compact overall dimensions and improving space efficiency.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If the support portions for camera and infrared lamp are made large, then the structural stability is improved, but the positional accuracy of camera and infrared lamp deteriorates

Engineering Contradiction:

Improvestructural stabilityVSAvoidpositional accuracy

Core Design Contradiction:

Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The design transitions from a bulky mechanical support structure to a precision-engineered bracket system that relies on accurate geometric relationships and positioning features. The support pins and holes are designed with specific dimensional tolerances to ensure precise positioning, replacing the need for large support portions that would provide stability through mass rather than precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If the optical axes of camera and infrared lamp are not parallel, then the assembly flexibility is improved, but the image quality at night deteriorates

Engineering Contradiction:

Improveassembly flexibilityVSAvoidimage quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The support bracket is pre-designed with the camera support portion and lamp support portion positioned such that their optical axes are parallel when the components are installed. This preliminary configuration ensures that as long as the camera module and infrared lamp are installed according to the design specifications, the optical axes will be automatically aligned in parallel, achieving both assembly flexibility and optimal nighttime image quality.
