Sliding Lid Housing With Bolt-Sleeve Linkage for Precise Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Housings with sliding lids for pinch valves face challenges in manageability and safety, particularly in precise lid insertion and prevention of loss, with conventional designs requiring significant space for lid removal and introducing force peaks during closure.
Innovation Solution
A housing design that combines a sliding lid mechanism with a hinge-like linkage, featuring a bolt and sleeve for axial and rotational movement, allowing the lid to pivot and slide, ensuring correct alignment and reducing space requirements, while a detachable bolt facilitates lid removal and axial fixation to prevent unintended opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid is designed as a sliding lid with guide edges engaging in lid guide grooves to prevent play, then reliability of closure is improved, but ease of operation deteriorates due to difficulty in precise lid insertion
Solution Approach 1:
A bolt-sleeve linkage mechanism serves as an intermediary between the operator and the sliding lid. The bolt acts as a guide rod that the sleeve follows, providing tactile feedback and mechanical assistance for precise alignment. This intermediary system mediates the insertion process, making it easier to achieve precise engagement of the guide edges with the lid guide grooves without compromising closure security.
2Ease of operation
If the sliding lid is completely removed to insert a hose into the housing body, then ease of operation for hose insertion is improved, but space requirements increase by at least the lid length
Solution Approach 1:
The lid system is segmented into two functional parts: the lid body that slides on the housing body for closure, and the bolt-sleeve linkage that provides articulation and positioning. This segmentation allows the lid to be partially disassembled or repositioned without complete removal, enabling hose insertion through smaller clearances while maintaining the sliding closure function.
Solution Approach 2:
The bolt-sleeve linkage introduces dynamic positioning capability to the lid system. The sleeve can slide along the bolt to adjust the lid's position and orientation, allowing the lid to be repositioned for hose access without requiring complete removal. This dynamic adjustment reduces the fixed space clearance needed compared to conventional sliding lids.
3Ease of manufacture
If a conventional sliding lid is used, then manufacturing simplicity is improved, but loss prevention deteriorates as lids become lost or confused with others
Solution Approach 1:
The bolt-sleeve linkage introduces asymmetric features to the lid design. The bolt has a specific orientation and the sleeve has a defined position relative to the lid, creating an asymmetric configuration that is easier to identify and match to the correct housing body. This asymmetric positioning prevents confusion between identical lids in complex media control systems while adding minimal manufacturing complexity.

AI summary
A housing having a housing body (100) carries on the outside of one of the side walls (110) a bolt (500) aligned parallel to the lid guide grooves (120) and the lid (200) carries a sleeve (222) fixed to a tab (220) projecting over the upper edge of the corresponding side wall (110) of the housing body (100) and aligned coaxially with the bolt (500). The sleeve (222) engages around the bolt (500) to form an axially and rotationally movable sliding bearing.
