Solution Overview

Problem

Existing devices for connecting conductor elements to connection components often fail to provide sufficient fixation, leading to potential damage and marks on the conductor elements due to excessive force application.

Innovation Solution

A clamping device with a reversibly deformable clamping body and a dimensionally stable bearing body is used to temporarily fix conductor elements, allowing for controlled application of force and preventing damage through a clamping mechanism that can switch between clamped and unclamped states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If gripping devices are used to fix conductor elements, then fixation is achieved, but marks or damage to the insulation occur due to excessive local force

Engineering Contradiction:
Improvefixation of conductor elementVSAvoidmarks or damage to insulation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The clamping device applies force through a distributed clamping surface rather than concentrated gripping points. The clamping body contacts the conductor element along an extended surface, distributing the clamping force uniformly to avoid local stress concentrations that would cause marks or damage to the insulation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The clamping device establishes fixation before the insertion process begins, maintaining continuous secure holding throughout the insertion sequence. This preliminary and sustained clamping action prevents the conductor element from shifting or requiring excessive force during insertion, thereby avoiding damage.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If gripping devices apply force to fix conductor elements, then insertion is enabled, but sufficient fixation is not achieved in certain directions

Engineering Contradiction:
Improveinsertion capabilityVSAvoidfixation in all directions
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The clamping device transitions from conventional single-axis gripping to multi-directional clamping by positioning clamping bodies that can apply restraining forces in multiple spatial directions simultaneously. This dimensional expansion of the clamping approach ensures the conductor element is secured against movement in all relevant directions during insertion.

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

Solution Approach 2:

The clamping device employs counteracting clamping forces applied in opposite directions to balance and restrain the conductor element comprehensively. By applying forces that counterbalance potential movement in all directions, the device achieves reliable fixation without requiring excessive force in any single direction.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

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 ensures secure and damage-free insertion of conductor elements by providing homogeneous force application, preventing marks or damage while allowing for easy release, thus improving the connection process.

Implementation Method 1

the at least one clamping body is formed from a reversibly elastically deformable material or a reversibly elastically deformable material structure; the at least one clamping body is thus reversibly deformable
