Vertical Weaving Loom with Hooked Guide Beams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat weaving looms are unable to convey continuous or loosely connected materials through the shed due to diameter and strength limitations of weft threads, and cannot store or handle materials like cables or hoses that are longer than a shuttle can manage.
Innovation Solution
The weaving loom is rotated 90° with the cloth beam at the bottom, using hooks anchored in guide beams to guide warp threads, allowing for a 90° shed formation that can accommodate continuous or loosely connected materials, and enabling the introduction of materials that exceed traditional shuttle limitations by alternating between open and closed shed states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional weaving technologies (shuttles, grippers, nozzles) are used to transport weft thread, then the weft thread can be inserted through the shed, but the diameter and strength of the weft thread are limited by the shed diameter and the technology used
Solution Approach 1:
The patent inverts the conventional weaving approach by rotating the loom 90° and changing the orientation of the shed from horizontal to vertical. This inversion allows continuous material to be fed from above through the vertical shed space, bypassing the limitations of traditional weft insertion methods and enabling the use of materials with various diameters and strengths including cables and hoses
2Length of moving object
If the shed diameter is limited by conventional weaving technology, then weft thread insertion is possible, but continuous material longer than shuttle capacity cannot be conveyed
Solution Approach 1:
By inverting the loom orientation and creating a vertical shed, the patent enables continuous material to be fed from above in a single long piece without requiring storage on shuttles or complex bobbin systems. The vertical configuration allows the material to pass through the shed space naturally under its own weight or with minimal propulsion
Solution Approach 2:
The patent enables continuous material to be fed through the shed without interruption, cutting, or re-threading. The vertical shed configuration and hook-based guidance system allow a single continuous piece of material to pass through multiple cycles of the weaving process, eliminating the need for frequent shuttle reloading
3Ease of operation
If conventional flat weaving loom configuration is used, then traditional weaving operations can be performed, but loose material or loosely connected material cannot be moved to its place between warp threads
Solution Approach 1:
The patent rotates the conventional flat weaving loom by 90° so that the cloth beam is at the bottom and the shed becomes vertical. This inversion creates a configuration where loose material can be fed from above between the warp threads and through the shed space, enabling handling of materials that cannot be managed by traditional shuttle, gripper, or nozzle methods
Solution Approach 2:
The patent introduces hooks anchored in guide beams as intermediary elements to capture and guide the loose material through the shed. These hooks act as mediators that can grasp and transport various types of loose or continuous material through the vertical shed space and onto the cloth beam, facilitating the insertion of materials that would otherwise be impossible to handle
4Shape
If rigid heddle system with shafts is used, then traditional shed formation is achieved, but the loom cannot accommodate continuous material feeding from above between guide beams
Solution Approach 1:
The patent replaces the rigid heddle system with shafts with a configuration where guide beams with hooks are positioned to receive material from above. The shed formation is maintained through the alternating positioning of hooks on opposite guide beams, but the material feeding configuration is inverted to allow continuous input from the top rather than from shuttles or grippers
Solution Approach 2:
The patent employs movable guide beams that can alternate between open and closed positions to dynamically form the shed. This dynamic configuration allows the guide beams to open for material insertion from above and then close to form the shed for weaving operations, providing adaptability for continuous material feeding while maintaining proper shed formation
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
Enables the weaving of materials like cables and hoses without severing them, and allows for the production of unique woven fabrics with integrated continuous or loose material strands, such as wool and irrigation hoses, which can serve as soil covers and prevent water evaporation.
Implementation Method 1
The cloth beam is situated below the respective formed shed and, by virtue of gravity, forms a natural detent toward the bottom

AI summary
A weaving loom for inserting continuous material, or loosely connected material or material in pieces, in which the warp threads run in the downward direction from the warp beam to the cloth beam and herein are individually held by hooks which are anchored in guide beams between the upper warp beams and the lower cloth beam.
