Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly process of camera modules is complex and requires multiple parts, leading to increased manufacturing costs and time.
Innovation Solution
A camera module design featuring a cover part with a lens guide to prevent lens removal, an O-ring for sealing, and a back cap that is threaded onto the cover part to securely fix the lens, reducing the number of parts and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate parts are used to assemble the camera module, then the lens can be securely fixed and sealed, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple separate components (cover part, lens guide, and back cap) into an integrated assembly structure. The lens guide is formed as part of the cover part, and the back cap integrates the sealing and fixation functions, reducing the number of discrete parts while maintaining secure lens fixation and sealing.
Solution Approach 2:
The back cap serves multiple functions simultaneously: it seals the camera module opening, fixes the lens in position, and provides structural support. The lens guide structure also serves dual purposes by both guiding lens installation and preventing lens removal, thereby reducing overall assembly complexity.
2Reliability
If multiple separate parts are used to assemble the camera module, then the lens can be securely fixed and sealed, but the manufacturing cost increases
Solution Approach 1:
By integrating the lens guide with the cover part and combining sealing and fixation functions into the back cap, the patent reduces the total number of parts that need to be manufactured, stored, and assembled. This integration lowers manufacturing costs while maintaining reliable lens fixation through the unified structural design.
3Reliability
If multiple separate parts are used to assemble the camera module, then the lens can be securely fixed and sealed, but the assembly time increases
Solution Approach 1:
The integration of the lens guide with the cover part and the consolidation of sealing and fixation functions in the back cap reduce the number of assembly steps. Fewer parts mean fewer handling and assembly operations, thereby reducing assembly time while maintaining secure lens fixation through the integrated structure.
Solution Approach 2:
The lens guide is pre-formed as part of the cover part structure, and the back cap is designed with integrated sealing and fixation features. This preliminary preparation of multi-functional components allows for faster assembly since the lens can be directly installed and secured in fewer steps without requiring separate operations for guidance, sealing, and fixation.
4Device complexity
If a simple assembly structure is used, then the assembly process is simplified, but the lens may not be securely fixed
Solution Approach 1:
The back cap is designed as a multi-functional component that simultaneously provides sealing, lens fixation, and structural support. This consolidation of multiple functions into a single component simplifies the overall assembly structure while ensuring secure lens fixation through the integrated design that combines several protective and securing features.
5Device complexity
If a simple assembly structure is used, then the assembly process is simplified, but the sealing may be insufficient
Solution Approach 1:
The back cap integrates multiple functions including sealing, fixation, and structural support into a single component. This multi-functional design simplifies the assembly structure by reducing the number of separate parts while maintaining effective sealing through the integrated sealing mechanism built into the back cap design.
