Clamping Wedge Mechanism for Leno Weave Harness Cord Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of harness cords in existing clamping apparatuses for leno weave apparatuses is complex due to the guidance of loop-like ends, increasing assembly time.
Innovation Solution
A clamping apparatus with a clamping wedge and wedge receiver device is used, where the harness cord is gripped between the wedge and receiver, with a spring for fixation and angled contact surfaces to maintain the clamping connection, allowing for easy assembly and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the harness cord is guided in the form of a loop through an upper clamping opening of an elastic coupling member, then a clamping connection is achieved, but the assembly process becomes complex and assembly time increases
Solution Approach 1:
The clamping apparatus is divided into distinct functional components: a wedge receiver device with a clamping opening and a separate clamping wedge. This segmentation allows the wedge to be independently manipulated and inserted, simplifying the assembly process compared to guiding a loop through an elastic member.
Solution Approach 2:
Instead of guiding the harness cord in a loop through an opening (as in the prior art), the invention inverts the approach by using a wedge that is inserted into a receiver device to create the clamping action. The wedge is displaced into the wedge receiver device, and the clamping connection is established by the wedge's interaction with the clamping opening, rather than by threading a loop through it.
2Reliability
If a metal sleeve is pushed over the coupling member to maintain a clamping connection, then the connection is secured, but the assembly design becomes more complex
Solution Approach 1:
The invention extracts and eliminates the metal sleeve component from the assembly. Instead of using a sleeve pushed over the coupling member, the clamping connection is maintained through the wedge receiver device and clamping wedge mechanism, where the wedge's displacement and the spring's action provide the necessary clamping force without requiring an additional sleeve component.
Solution Approach 2:
The wedge receiver device serves multiple functions: it receives the wedge, provides the clamping opening for the harness cord, and incorporates a spring mechanism to maintain clamping force. This multi-functionality replaces the need for separate components like the metal sleeve and elastic coupling member, simplifying the overall design.
3Ease of operation
If the clamping wedge is displaced into the wedge receiver device, then the harness cord is clampingly gripped, but additional means are required to fix the wedge position
Solution Approach 1:
The spring mechanism automatically maintains the clamping wedge in the clamping position within the wedge receiver device. The spring's elastic force continuously pushes the wedge against the harness cord, providing self-sustaining clamping pressure without requiring additional fixing means or complex locking mechanisms.
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
The solution simplifies the assembly process by providing a secure and adjustable clamping mechanism that reduces assembly time and ensures a reliable connection between the harness cord and lifting heddle.
Implementation Method 1
The means advantageously comprise a spring that acts on the clamping wedge. This means that the clamping wedge is under the load of a spring. The force of the spring thus acts on the clamping wedge in the longitudinal direction of the lifting heddle such that the clamping connection for the harness cord is maintained.
Implementation Method 2
the clamping apparatus has a clamping wedge and a wedge receiver device arranged at the end of the lifting heddle, wherein the wedge receiver device displaceably receives the clamping wedge in the longitudinal direction of the lifting heddle, wherein the harness cord is clampingly gripped between the wedge receiver device and the clamping wedge
