Solution Overview
Problem
Warp sizing apparatuses lack a configuration to effectively receive and manage overflowing sizing liquid, leading to inefficiencies and increased operator burden during cleaning due to liquid hardening and accumulation.
Innovation Solution
Incorporating a receiving part with an inclined receiving surface and a restriction surface that blocks the flow of overflowing sizing liquid, guiding it towards a collection path to prevent hardening and facilitate easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a sizing liquid pool is formed in a wedge-shaped region above circumscribed rolls, then sizing is performed on the warp sheet, but overflowing sizing liquid accumulates and hardens on the receiving surface, increasing operator burden during cleaning
Solution Approach 1:
The receiving part is divided into two functional surfaces: an inclined receiving surface for guiding liquid flow and a restriction surface for blocking upward flow. This segmentation allows each surface to perform its specific function efficiently, preventing liquid accumulation and hardening on the receiving surface.
Solution Approach 2:
The receiving surface is designed with an inclination in the front-rear direction, adding a dimensional aspect to liquid guidance. This inclined geometry naturally directs overflowing sizing liquid toward the collection path, preventing accumulation on the receiving surface.
2Quantity of substance
If the receiving surface is horizontal, then liquid can accumulate for collection, but it hardens on the surface, increasing cleaning difficulty
Solution Approach 1:
The receiving surface is designed with an inclination in the front-rear direction, adding a dimensional aspect to liquid guidance. This inclined geometry naturally directs overflowing sizing liquid toward the collection path, preventing accumulation on the receiving surface.
Solution Approach 2:
The receiving part is divided into two functional surfaces: an inclined receiving surface for guiding liquid flow and a restriction surface for blocking upward flow. This segmentation allows each surface to perform its specific function efficiently, preventing liquid accumulation and hardening on the receiving surface.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively collects and redirects overflowing sizing liquid, preventing it from hardening on the receiving surface, thus reducing the operator's cleaning burden and maintaining apparatus efficiency.
Implementation Method 1
the overflowing sizing liquid received on the receiving surface flows along an inclination on the receiving surface
Implementation Method 2
a restriction surface extending upward from an upper end of the receiving surface with respect to the front-rear direction and configured to block flow of the overflowing sizing liquid
