Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing CCD camera technology requires separate manufacturing for AC and DC power variants, limiting manufacturer flexibility and increasing costs due to the need for distinct assembly lines and power conversion systems.
Innovation Solution
A CCD camera apparatus with a modular AC/DC power driving unit that allows selective engagement with either AC or DC power, featuring a housing with an AC/DC power driving board that converts AC to DC power, enabling the camera to operate with either power type without requiring separate manufacturing setups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate PCBs are used for AC and DC power, then the camera can operate in different power environments, but the manufacturing complexity and costs increase
Solution Approach 1:
The patent applies universality by designing a single rear PCB that can handle both AC and DC power inputs. The PCB includes an AC power input interface and a DC power input interface, allowing the same camera model to adapt to different power sources without requiring separate PCB designs for AC and DC variants.
Solution Approach 2:
The patent merges the previously separate AC power PCB and DC power PCB into a single integrated rear PCB. This unified design consolidates power processing circuits, control logic, and interfaces for both AC and DC power sources onto one board, reducing manufacturing complexity while maintaining versatility.
2Adaptability or versatility
If separate PCBs are used for AC and DC power, then the camera can operate in different power environments, but the production costs increase
Solution Approach 1:
The universal rear PCB design allows a single camera model to be produced for both AC and DC power environments, eliminating the need to manufacture separate camera variants. This reduces tooling costs, assembly line setup costs, and inventory complexity while maintaining the ability to operate in different power environments.
Solution Approach 2:
The rear PCB is designed with segmented power input interfaces - a separate AC power input interface and a separate DC power input interface - that can be selectively connected based on the intended power source. This modular interface design allows the same PCB to support multiple power sources without requiring complete separate designs.
3Reliability
If separate assembly lines are used for AC and DC power cameras, then quality control is maintained, but productivity decreases
Solution Approach 1:
The patent merges the assembly processes for AC and DC power cameras into a single unified assembly line. Since both power variants use the same rear PCB design with integrated power processing circuits and control logic, the same assembly procedures, quality control checkpoints, and testing protocols can be applied to both AC and DC configured cameras, thereby improving productivity while maintaining quality control.
