Filter Mounting Block Stamping and Segmented Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter mounting blocks, formed through die casting, suffer from instability and deformation issues due to suspended connections and inadequate locking mechanisms, leading to unreliable filter performance.
Innovation Solution
The filter design incorporates a mounting block formed by stamping a sheet, featuring a reference surface with stop holes and connection holes that securely abut against the cover plate, ensuring stability and reliability through improved locking and positioning of the support seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a mounting block is formed by die casting with a suspended connection to the locking screw, then the mounting block can be manufactured with complex geometry, but the connection becomes unstable and deformation occurs when locking force is applied
Solution Approach 1:
The mounting block is divided into two separate components: a block body and a locking screw. The locking screw is inserted through a through-hole in the block body and secured with a locking piece, creating a modular assembly that eliminates the suspended connection problem while maintaining manufacturing flexibility.
Solution Approach 2:
A locking piece is introduced as an intermediary component to secure the locking screw within the mounting block. This locking piece threads into the block body and prevents the screw from loosening or detaching, providing a reliable mechanical connection that can withstand locking forces without deformation.
2Ease of operation
If the mounting block uses a suspended connection structure, then the design allows for simplified assembly, but the locking screw cannot be easily locked and deformation occurs under high locking force
Solution Approach 1:
The mounting block is segmented into a block body and a separate locking screw assembly. The through-hole design allows the screw to pass completely through, enabling simple assembly while the distinct screw component can be independently tightened and locked without deforming the main block structure.
Solution Approach 2:
The locking piece acts as a mediator that secures the locking screw within the block body. It provides a threading mechanism that allows the screw to be firmly fixed and locked, enabling high locking forces to be applied without causing deformation to the mounting block or cover plate.
3Device complexity
If the mounting block directly connects to the cover plate without a reference surface, then the structure can be simpler, but the positioning of the support seat becomes unstable
Solution Approach 1:
A reference surface is pre-formed on the mounting block that abuts against the cover plate before the locking operation. This reference surface establishes a stable, predetermined positioning for the support seat, ensuring consistent alignment and stability throughout the filtering operation without requiring complex adjustment mechanisms.
