Solution Overview

Problem

Existing jacquard machine modules are difficult to remove and replace due to the need to unhook and rehook harness cords, leading to laborious maintenance and unnecessary loads that can cause deformation, especially when replacing hoisting cords or selection devices.

Innovation Solution

A module with displaceable anchor elements that can be pressed against a contact profile for secure installation and easily moved to a removal position, allowing for quick and simple removal without deforming the module, and featuring a guide mechanism for lateral movement or rotation to facilitate removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the module is securely installed in the jacquard machine using anchor elements pressed against a contact profile, then the module stability and operational reliability are improved, but the difficulty of removal and maintenance increases

Engineering Contradiction:
Improvemodule installation stabilityVSAvoidmodule removal difficulty
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The anchor element is designed to be displaceable between a first position of use (pressed against the contact profile for secure installation) and a second removal position (disengaged from the contact profile for easy removal). This dynamic positioning allows the same component to provide both secure installation during operation and easy removal during maintenance, resolving the contradiction between reliability and ease of repair

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the anchor element is held pressed against the contact profile during operation, then the module maintains correct position and prevents deformation, but unnecessary loads are exerted on the module structure

Engineering Contradiction:
Improvemodule positional stabilityVSAvoidload on module structure
Core Design Contradiction:
Stability of the object's compositionVSForce

Solution Approach 1:

The anchor element transitions from a static pressed position to a dynamic displaceable position. During operation, it is pressed against the contact profile to maintain stability. During removal, it is displaced to a second position where it is no longer pressed against the profile, eliminating unnecessary loads. This dynamic behavior allows the system to achieve stability when needed without imposing continuous harmful forces

Inventive Principle:
Principle #15Dynamics

3Loss of time

If the module design allows for easy removal and replacement, then maintenance time and downtime are reduced, but the secure installation and operational stability may be compromised

Engineering Contradiction:
Improvemaintenance downtimeVSAvoidinstallation security
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The module is designed with separable components, specifically the displaceable anchor element that can be independently positioned. This segmentation allows the module to be quickly removed by displacing the anchor element to the removal position, reducing maintenance downtime.同时, when the anchor element is positioned in the first position of use, it provides secure installation and operational stability, thus resolving the contradiction between quick maintenance and reliable installation

Inventive Principle:
Principle #1Segmentation
