Solution Overview

Problem

Existing tape dampers for textile strips have a structural design that limits the compactness and penetration path of the belt, resulting in a larger damper size for the same belt penetration length.

Innovation Solution

The arrangement of vertically spaced upper deflection rollers combined with horizontally spaced lower deflection rollers into a group, allowing the belt to be guided alternately in a spiral shape, reduces the damper's structural size while maintaining the belt's penetration path, and includes displacement means to achieve an offset in the axial direction, enabling a longer penetration path with the same damper length.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If upper deflection rollers are arranged side by side with horizontal spacing like the lower deflection rollers, then the belt can be guided through the damper, but the damper's structural size increases for the same belt penetration length

Engineering Contradiction:
Improvedamper structural sizeVSAvoidbelt penetration path
Core Design Contradiction:
Length of stationary objectVSLength of moving object

Solution Approach 1:

The upper deflection rollers are arranged vertically one above the other instead of horizontally side by side. This dimensional change from horizontal to vertical arrangement allows the belt to follow a spiral path through the damper, increasing the penetration path length without increasing the horizontal footprint of the damper structure.

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

Solution Approach 2:

The belt is guided in a spiral shape through the damper by the vertically arranged upper deflection rollers and horizontally spaced lower deflection rollers. This curved spiral path allows the belt to traverse a longer distance within a compact damper structure, effectively increasing the penetration path without proportionally increasing the damper's external dimensions.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Length of moving object

If the damper length is kept the same, then the structural size is reduced, but the penetration path of the belt is increased through spiral guidance

Engineering Contradiction:
Improvebelt penetration pathVSAvoiddamper length
Core Design Contradiction:
Length of moving objectVSLength of stationary object

Solution Approach 1:

By arranging the upper deflection rollers vertically one above the other rather than horizontally, the patent creates a three-dimensional spiral path for the belt. This allows the belt to gain additional penetration path length by utilizing the vertical dimension, thereby increasing the effective treatment path without extending the horizontal length of the damper.

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

Solution Approach 2:

The spiral guidance path effectively nests multiple belt passes within the same damper length. The belt loops back on itself in a compact spiral configuration, allowing the penetration path to be longer than the physical length of the damper, similar to how a nested doll contains multiple levels within a compact form.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Length of moving object

If displacement means are added to guide the strip alternately in a spiral form, then the penetration path is increased, but the device complexity increases

Engineering Contradiction:
Improvebelt penetration pathVSAvoiddisplacement means mechanism
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The displacement means creates dynamic, alternating guidance of the belt through the spiral path. By periodically shifting the belt position and guiding it alternately over the vertically arranged upper deflection rollers, the system achieves a longer penetration path through motion control rather than through complex static structural arrangements.

Inventive Principle:
Principle #15Dynamics

AI summary

The reductive band-ware after-treatment damper has multiple vertically-spaced upper and lower guide rollers (5,6,7,8). Two upper-stacked guide rollers are arranged in a vertically-spaced manner, where two lower guide rollers are arranged and spaced next to each other in a horizontal manner. The upper guide rollers are combined into a group (G').
