Solution Overview

Problem

Existing pressing tools for producing compression joints have limited stroke length, requiring multiple jointing clamp strokes or the use of specialized tools to achieve the necessary deformation work, which is inefficient and labor-intensive.

Innovation Solution

A jointing clamp with both main and auxiliary inlet contours that can be activated or deactivated, allowing for extended stroke capabilities by using the auxiliary contour for additional movement beyond the main contour, enabling a single jointing clamp to achieve the required deformation with two strokes.

1Productivity

If a pressing tool with limited stroke length is used, then the device complexity is reduced, but the productivity decreases because multiple jointing clamp strokes are required to achieve the necessary deformation work

Engineering Contradiction:

Improvedeformation work efficiencyVSAvoidjointing clamp structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The jointing clamp is divided into two functional parts: a main inlet contour for the primary pressing stroke and an auxiliary inlet contour for the additional stroke. This segmentation allows the single clamp to perform multiple deformation stages, effectively extending its functional stroke length without requiring multiple clamps or complex specialized equipment

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The jointing clamp is designed with multi-functionality by incorporating both main and auxiliary inlet contours that can be selectively activated. This allows a single universal clamp design to handle both standard pressing operations and extended stroke operations, eliminating the need for specialized tools while maintaining simplicity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If multiple jointing clamps or specialized tools are used to achieve extended stroke, then the deformation work capability is improved, but the ease of operation deteriorates due to increased operational complexity

Engineering Contradiction:

Improvedeformation work capabilityVSAvoidpressing operation

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The main inlet contour and auxiliary inlet contour are merged into a single jointing clamp assembly, allowing the operator to perform extended stroke operations with one tool rather than switching between multiple clamps or specialized equipment. This merging simplifies the operational workflow while maintaining full deformation work capability

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A jointing clamp for producing a compression joint, comprising: an upper jointing clamp half that can be pivoted about a first pivoting axis and has an upper main inlet contour, a lower jointing clamp half that can be pivoted about a second pivoting axis and has a lower main inlet contour, an upper contour element with an upper auxiliary inlet contour that cooperates with the upper jointing clamp half in such a way that a movement of the upper contour element is transmitted to the upper jointing clamp half and a lower contour element with a lower auxiliary inlet contour that cooperates with the lower jointing clamp half in such a way that a movement of the lower contour element is transmitted to the lower jointing clamp half. The invention furthermore relates to a corresponding method for producing a compression joint.
