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

VSEngineering 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

Engineering Contradiction:
Improvesizing performanceVSAvoidcleaning burden
Core Design Contradiction:
ProductivityVSEase of operation

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
