Sewer Vehicle Tank Lid Layout for Higher Capacity in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sewer jetting vehicles face challenges in maximizing storage capacity for water and cleaning sludge while maintaining a compact design, especially when operating in cramped spaces and transitioning between distant points.
Innovation Solution
A sewer jetting vehicle with a storage tank featuring a tilting cover mechanism, including locking and implementation means that allow the cover to transition between closed and open positions, optimizing storage capacity by minimizing external projections and maximizing internal volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the storage tank volume is increased to maximize water and sludge capacity, then the storage capacity is improved, but the vehicle dimensions and space requirements worsen
Solution Approach 1:
The lid locking mechanism is nested within the lid structure itself, with locking cylinders and latches integrated into the lid's thickness rather than protruding externally. This nesting approach allows the storage tank to achieve maximum volume without the vehicle dimensions being increased by external locking components.
2Reliability
If external locking means are positioned on the lid, then the locking function is improved, but the external projections increase the vehicle's overall dimensions
Solution Approach 1:
The locking cylinders and latches are nested within the lid structure, with the locking means positioned inside the lid's thickness. The latches engage with the tank body from within the lid, eliminating external projections that would increase the vehicle's overall dimensions while maintaining reliable locking functionality.
Solution Approach 2:
The locking mechanism transitions from a traditional external side-view arrangement to an internal top-view arrangement. The locking cylinders are oriented perpendicular to the lid surface, with pistons moving in the vertical dimension rather than horizontally, allowing the locking function to be achieved without external lateral projections.
