Solution Overview

Problem

Existing cable mounting components for electrical devices, such as hand blenders, are not adaptable to varying cable diameters, requiring multiple strain relief designs and increased assembly effort due to the need for screws for fixation.

Innovation Solution

A cable mounting component comprising a cable support element and holder, where the support element can be manufactured in different dimensions, eliminating the need for screws and allowing for flexible adaptation to various cable diameters through engagement elements and deformation under tensile load, enabling secure strain relief without additional screws.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a screw is used to fix the cable element between two strain relief parts, then cable elements with different diameters can be fixed, but the assembly effort increases

Engineering Contradiction:
Improveadaptability to different cable diametersVSAvoidassembly effort
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention extracts the screw from the cable mounting component entirely. Instead of using a screw to clamp the cable between two strain relief parts, the cable holder is designed with a recess that directly receives and secures the cable element through the deformation of the cable support element under tensile load, eliminating the need for separate fastening elements

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The cable support element serves itself by deforming under tensile load to press the engagement element into the cable sheath. The component automatically adjusts and secures the cable through its own deformation rather than requiring an external screw mechanism, making the assembly process simpler and more intuitive

Inventive Principle:
Principle #25Self-service

2Reliability

If multiple differently dimensioned strain reliefs are used for different cable diameters, then each cable type can be properly secured, but the device complexity and cost increase

Engineering Contradiction:
Improvesecure cable fixationVSAvoidnumber of different strain relief designs
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cable holder is designed as a universal component that can accommodate cable elements of different diameters. The recess and cable support element are dimensioned to receive various cable sizes, and the deformation mechanism adapts to different cable diameters automatically, eliminating the need for multiple specialized strain relief designs

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention changes the parameter of the cable support element's dimensions. By manufacturing the cable support element in different dimensions while keeping the same basic design and mechanism, the system can adapt to different cable diameters without changing the overall structure or requiring multiple complex designs

Inventive Principle:
Principle #35Parameter changes

3Reliability

If a screw is used for fixing the cable element, then reliable fixation is achieved, but the cost and assembly effort increase

Engineering Contradiction:
Improvecable element fixation reliabilityVSAvoidmanufacturing cost and assembly complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The screw is completely removed from the cable mounting component. The fixation function is achieved through the deformation of the cable support element itself, which presses the engagement element into the cable sheath under tensile load, eliminating the need for separate fastening elements and reducing manufacturing cost

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the mechanical screw fastening system with a deformation-based fixation mechanism. Instead of using threads and clamping force from a screw, the system uses the elastic deformation of the cable support element to create fixation pressure, simplifying the mechanical system

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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 provides a cost-effective, flexible, and reduced-effort assembly method for securing cables of different diameters, allowing the same cable holder to be used across various dimensions by preassembling the cable element, thus enhancing the adaptability and reliability of cable mounting.

Implementation Method 1

When a tensile load is applied, the body of the cable support element can be deformed in such a way that the first engagement element is pressed into the cable sheath of the cable element

AI summary

The invention relates to a cable mounting component for an electrical appliance, in particular a hand-held domestic appliance, such as a hand blender. The cable mounting component comprises a cable carrier element having a cable carrier element body, which has a receiving side, wherein the cable carrier element is designed to hold a cable element on the receiving side, and a cable holder which can be attached to the electrical appliance, wherein the cable holder has a guide for the cable carrier element. The cable carrier element is further designed to be moved along the guide of the cable holder with the cable element at least partially looped around the cable carrier element body.
