Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Closed circuit television (CCTV) cameras using multiple fixed infrared modules are costly, power-consuming, and complex due to their multiple components.
Innovation Solution
A camera design incorporating a single infrared module that rotates with a platform, allowing it to cover all panning angles, reducing the need for multiple modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple fixed infrared modules are used around the camera, then infrared illumination coverage is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple infrared modules into a single rotating infrared module that pans across different angles. Instead of having multiple fixed modules positioned around the camera, one infrared module rotates to cover the same total angular coverage, thereby reducing component count while maintaining illumination coverage.
Solution Approach 2:
The infrared module transitions from a static fixed position to a dynamic rotating position. The module is mounted on a rotating platform that allows it to change its orientation and cover different panning angles, enabling a single module to perform the function previously requiring multiple fixed modules.
2Illumination intensity
If multiple fixed infrared modules are used around the camera, then infrared illumination coverage is improved, but power consumption increases
Solution Approach 1:
The patent merges multiple power-consuming infrared modules into a single rotating module. By consolidating the infrared illumination function into one module that rotates to different positions, the total power consumption is reduced while maintaining the same overall illumination coverage across the field of view.
3Illumination intensity
If multiple fixed infrared modules are used around the camera, then infrared illumination coverage is improved, but cost increases
Solution Approach 1:
The patent merges multiple expensive infrared modules into a single rotating module, directly reducing the bill of materials cost. The manufacturing cost is reduced by producing and assembling one infrared module with a rotation mechanism rather than multiple fixed modules, while achieving the same functional coverage.
