Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera devices for vehicle environment detection systems face challenges in efficient and versatile assembly, particularly in securely mounting a light-trap arrangement to a camera housing with a lens assembly, which affects the system's effectiveness and ease of service or part replacement.
Innovation Solution
The camera device incorporates a light-trap arrangement with resilient and fixed holding parts that snap into locking positions, ensuring secure front and rear locking mechanisms, allowing for easy assembly and disassembly, and a method for mounting the light-trap arrangement to the camera housing, facilitating quick and reliable attachment to a vehicle-mounted bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a light-trap arrangement is securely mounted to a camera housing using fixed adhesive bonding, then the light limitation function is reliable, but the assembly process becomes time-consuming and part replacement is difficult
Solution Approach 1:
The light-trap arrangement is divided into multiple segments with individual holding parts (front holding parts and rear holding parts) that can be independently engaged with corresponding housing holding parts. This segmentation allows for modular assembly where each segment can be attached separately, reducing overall assembly time while maintaining reliable light limitation through the combined effect of multiple engagement points.
Solution Approach 2:
The holding parts incorporate resilient elements that provide dynamic engagement capability. The resilient nature of the holding parts allows for quick snap-in assembly without requiring time-consuming adhesive bonding, while still providing reliable and secure mounting when engaged. This dynamic characteristic enables rapid assembly and disassembly while maintaining functional reliability.
2Reliability
If a light-trap arrangement is securely mounted to a camera housing, then the light limitation function is reliable, but the process becomes complex and difficult to service
Solution Approach 1:
By dividing the light-trap arrangement into segments with discrete holding parts, each segment can be independently removed and replaced. This segmentation simplifies service operations as technicians can replace individual segments rather than entire assemblies, making maintenance easier while the multiple engagement points ensure reliable light limitation when properly assembled.
Solution Approach 2:
The resilient holding parts enable easy engagement and disengagement through simple snap-in/snap-out actions. This dynamic characteristic makes part replacement straightforward for servicing, contrasting with fixed adhesive bonding which requires complex removal processes. The reliable light limitation function is maintained through the secure engagement of the resilient elements when properly assembled.
3Productivity
If a light-trap arrangement uses resilient snap-in holding parts, then assembly is quick and easy, but the securing strength may be insufficient compared to fixed bonding
Solution Approach 1:
Multiple holding parts (both front holding parts and rear holding parts) are combined to work together in providing the securing function. While each individual resilient holding part provides quick snap-in assembly, the cumulative effect of multiple engaged holding parts achieves sufficient overall securing strength comparable to fixed bonding methods, resolving the contradiction between assembly speed and securing strength.
