Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter plate handles in filter presses suffer from misalignment and waggling due to bolt hole clearances, leading to inaccurate mounting.
Innovation Solution
A filter plate handle design featuring a fixed plate and an insertion shaft with interference fit and wear-resistant block, secured by bolts, ensuring accurate alignment and stability through dual fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional filter plate handles are mounted using two or three bolts through bolt holes, then the handles can be fixed to the filter plate, but the clearance of the bolt holes causes misalignment and waggling of the handles
Solution Approach 1:
The patent introduces an insertion shaft as an intermediary component between the handle and the filter plate. The insertion shaft features a stepped structure with different diameter sections that provide precise positioning and alignment through interference fit, eliminating the alignment errors caused by bolt hole clearances in conventional direct bolting methods
Solution Approach 2:
The mounting structure is segmented into multiple functional components: the insertion shaft with stepped sections for different purposes (alignment, interference fit, bolting), and the handle body. This segmentation allows each component to perform its specific function optimally, with the insertion shaft handling alignment and positioning while bolts provide secure fastening
2Reliability
If the filter plate handle is securely fixed to prevent waggling, then alignment accuracy improves, but the structure becomes more complex
Solution Approach 1:
The patent merges multiple functions into the insertion shaft component: it serves as the alignment reference, provides interference fit for secure positioning, and acts as the mounting substrate for bolts. This consolidation achieves high mounting stability without proportionally increasing overall structural complexity, as the insertion shaft is a single integrated piece rather than multiple separate components
Solution Approach 2:
The insertion shaft features local quality variations through its stepped structure, with different diameter sections optimized for specific functions. The larger diameter section provides interference fit for rigid connection, while the smaller diameter section accommodates bolts. This localized differentiation achieves high stability without making the entire structure unnecessarily complex

AI summary
A filter plate handle is provided, an insertion shaft of which protrudes out of two side plate surfaces of a fixed plate, and the insertion shaft is fixedly connected to the fixed plate, portions protruding out of the two sides of the fixed plate are a first section and a second section respectively, the first section of the insertion shaft can be inserted into an insertion hole of a filter plate by interference fit, so as to ensure accurate alignment and assembly with the filter plate. The second section of the insertion shaft is provided with a wear-resistant block, which is configured to be in contact with a main beam and provide sliding support. The fixed plate is provided with at least two bolt holes and is fixedly connected to the filter plate by at least two bolts, so as to further realize fastening.
