Camera Unit Hose Connection via Integrated Pressing Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera units for vehicles require additional components and increased manufacturing time due to the need for separate fastening members to connect the spray nozzle and hose, leading to higher costs.
Innovation Solution
A camera unit design that incorporates a supporting bracket with a through-hole allowing the hose to pass through and be connected to the nozzle without additional fastening members, utilizing a pressing part to prevent hose detachment and reduce component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate fastening member is used to connect the hose and spray nozzle, then the connection reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The pressing part is integrated into the supporting bracket, merging the fastening function with the supporting structure. This eliminates the need for separate fastening members while maintaining connection reliability, directly resolving the contradiction between connection reliability and device complexity
Solution Approach 2:
The supporting bracket serves multiple functions: it supports the camera, provides structural support, and includes the pressing part for securing the hose. This multi-functionality reduces the total number of components while maintaining all necessary functions, addressing both the reliability and complexity concerns
2Reliability
If a separate fastening member is used to connect the hose and spray nozzle, then the connection reliability is improved, but the manufacturing time increases
Solution Approach 1:
By integrating the pressing part into the supporting bracket, the assembly process is simplified. The hose can be directly secured to the bracket without additional fastening steps, reducing manufacturing time while maintaining connection reliability through the pressing mechanism
Solution Approach 2:
The pressing part is pre-formed as part of the supporting bracket structure. During assembly, the hose is simply inserted and secured by the pre-existing pressing part, eliminating the need for separate fastening operations and reducing manufacturing time
3Reliability
If additional fastening members are used, then the hose connection security is improved, but the manufacturing cost increases
Solution Approach 1:
The pressing part is formed as an integrated feature of the supporting bracket, eliminating the need for separate fastening members. This reduces component count and assembly steps, directly lowering manufacturing cost while maintaining hose connection security through the pressing mechanism
Solution Approach 2:
The supporting bracket provides its own fastening function through the integrated pressing part, eliminating the need for external fastening members. This self-sufficiency reduces manufacturing complexity and cost while ensuring secure hose connection

AI summary
A camera unit includes a camera, a supporting part, a nozzle, and a hose. The supporting part supports the camera on a front surface side thereof, has a back surface side fixed on a body for placement thereof, and has a through-hole that penetrates through the front and back surface sides. The nozzle has a proximal end part inserted into the through-hole from the front surface side and a distal end part that is arranged to be capable of discharging a fluid toward a lens of the camera. The hose passes through an opening of the through-hole on the back surface side and is connected to the proximal end part of the nozzle in the through-hole to supply the fluid to the nozzle. Furthermore, the supporting part has a pressing part that protrudes in a radial direction thereof in the through-hole and presses an outer circumference of the hose.
