Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional sliver creel gate systems require numerous parts for assembly, leading to increased costs and complexity, with issues such as twisting and bending of long support profiles, exposure to dust and abrasion, and laborious assembly processes due to open receiving grooves.

Innovation Solution

A support profile with enclosed side walls, a bottom section, and a cover section, featuring through openings for shafts that stabilize and house the drive mechanism, reducing the need for additional parts and allowing assembly from above, while a sensor system detects sliver tears or empty containers to prevent damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the support profile length is increased to accommodate larger diameter storage containers, then the storage capacity increases, but the risk of twisting and bending increases

Engineering Contradiction:

Improvestorage capacityVSAvoidstructural stability

Core Design Contradiction:

Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The support profile is divided into multiple segments that can be connected together. This allows the overall length to be increased for larger storage capacity while each individual segment maintains sufficient structural stability and resistance to twisting and bending.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If numerous individual parts are used for assembly, then the functionality and adaptability are improved, but the device complexity and assembly costs increase

Engineering Contradiction:

Improveassembly flexibilityVSAvoidnumber of parts

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple functional components are integrated into the support profile structure itself. The receiving grooves are formed directly in the support profile, eliminating the need for separate T-nuts and retaining elements. This reduces the number of individual parts while maintaining the necessary functionality and adaptability.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If T-nuts are inserted through open grooves from one end, then the assembly process is simplified, but the labor intensity and time required increase due to the need to push T-nuts through long distances

Engineering Contradiction:

Improveassembly simplicityVSAvoidassembly time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

Instead of inserting T-nuts from one end through the entire length of the support profile, the receiving grooves are designed to allow access from above. This enables workers to insert and position T-nuts directly at the assembly location without the laborious process of pushing them through long distances from one end.

Inventive Principle:

Principle #13The other way round (Inversion)

4Ease of operation

If the receiving grooves are open towards the floor, then the assembly access is improved, but the sliver material is exposed to dust and abrasion

Engineering Contradiction:

Improveassembly accessibilityVSAvoidcontamination exposure

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The receiving grooves are reoriented to be open towards the top of the support profile instead of towards the floor. This dimensional change in opening direction allows assembly access from above while simultaneously protecting the sliver material from exposure to dust and abrasion generated during operation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A support profile (10) has two spaced-apart and parallel side walls (15, 22; 16, 23) and a base section connecting them at their edges, which point in the same direction and extend along the longitudinal extent of the support profile (10). It has a cover section (11) connecting the side walls (15, 22; 16, 23) at their edges, which extend along the longitudinal extent of the support profile (10) and face away from the base section. Viewed in the longitudinal direction of the support profile (10), the side walls (15, 22; 16, 23), the cover section (11), and the base section completely enclose, at least partially, the interior of the support profile (10). Fastenings (19) are provided on the base section for fixed attachment to a respective support foot (5). On the side walls (15, 22; 16, 23) there are first passage openings (13) aligned with each other, viewed transversely to the longitudinal extent of the supporting profile (10).A shaft (44) is freely rotatable and stationary through one of these pairs of through-holes and is rotationally connected to a drive element (60) via a section (45) located inside the support profile (10). On one side wall, the shaft (44) has a drive section (41) with a circular cross-section and an outer surface to carry fiber sliver along during rotation. A creel (4) has a frame (5, 10) with feet (5) that rest on a base, and the support profile (10) attached to it. In an arrangement (1) with a spinning preparation machine (2) and a creel (4), the support profile (10) is positioned parallel to and in front of the fiber sliver feed direction of the machine (2). The drive element (60) rotates the shaft(s) (44) to convey fiber sliver to the machine (2).
