Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting RF shielding boxes inside endoscope connectors are cumbersome and time-consuming, requiring regular fastening elements like screws, which complicates disassembly and assembly.
Innovation Solution
A cylinder-shaped RF shielding box with conically tapered ends and protruding rectangular plates that engage with internal mechanical structures within the connector, allowing for secure mounting without screws, enabling easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soldering joints are used to fix the shielding box, then the shielding box is securely fixed, but disassembling and assembling takes a lot of time
Solution Approach 1:
The shielding box is divided into a box body and separate mounting plates, allowing the mounting plates to be independently attached to the connector housing. This segmentation enables the shielding box to be quickly removed and reinstalled without affecting the structural integrity of the connector, resolving the contradiction between secure fixation and quick assembly/disassembly.
Solution Approach 2:
The mounting plates are pre-attached to the connector housing with mounting elements (screws or clips) before the shielding box is installed. This preliminary action allows the shielding box to be quickly snapped into place without requiring time-consuming soldering or complex fastening operations, while still providing secure fixation during use.
2Reliability
If regular fastening elements like screws are used, then the shielding box is securely mounted, but the mounting process becomes complex and time-consuming
Solution Approach 1:
The mounting structure is segmented into separate mounting plates that are attached to the connector housing, rather than using complex integrated fastening mechanisms. This simplification reduces the overall device complexity while maintaining secure mounting through the distributed attachment points provided by the mounting plates.
Solution Approach 2:
Mounting plates serve as intermediary elements between the shielding box and the connector housing. These plates provide a simplified interface that uses basic mounting elements (screws or clips) rather than complex fastening mechanisms, reducing device complexity while ensuring reliable mounting through the intermediate mounting plates.
3Ease of manufacture
If additional parts are used to mount the shielding box, then the shielding box can be mounted, but the mounting process becomes tedious
Solution Approach 1:
The mounting plates are pre-attached to the connector housing with all necessary mounting elements before the shielding box is installed. This preliminary preparation eliminates the need for operators to handle multiple separate parts during assembly, making the mounting process simple and straightforward while maintaining manufacturing flexibility.
Solution Approach 2:
The mounting plates combine multiple functions into a single component: they provide structural support, serve as attachment points for mounting elements, and facilitate the installation and removal of the shielding box. This merging of functions reduces the number of separate parts needed and simplifies the mounting operation.
