Solution Overview

Problem

The increasing number of elongated objects in vehicles, such as electrical cables and ducts, poses challenges in efficient fitting, securing, and assembly, leading to time-consuming and costly processes, with potential functional impairment and safety risks.

Innovation Solution

A fixing arrangement with first and second fixating members featuring protrusions that interlock to securely fasten elongated objects in gaps between protrusions, allowing for quick, simple, and cost-effective installation and removal, while occupying minimal space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional bracket arrangements or straps are used to fix elongated objects, then the objects can be secured, but the assembly process becomes burdensome and time-consuming

Engineering Contradiction:

Improvesecure fixationVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The fixing arrangement is divided into multiple modular fixating members, each with multiple protrusions that can independently secure different elongated objects. This segmentation allows for parallel assembly of multiple objects simultaneously, reducing overall assembly time while maintaining secure fixation through the distributed modular structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fixating members are designed with protrusions that automatically engage with gaps between adjacent objects when the members are positioned together. This self-aligning, self-latching mechanism eliminates the need for complex manual adjustment or additional fastening steps, enabling quick assembly while ensuring reliable secure fixation through the interlocking protrusion-gap structure

Inventive Principle:

Principle #25Self-service

2Reliability

If multiple traditional fixing methods are used for each elongated object, then secure fixation is achieved, but assembly costs increase

Engineering Contradiction:

Improvesecure fixationVSAvoidassembly cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

Multiple fixating members with multiple protrusions each are combined into a single integrated fixing arrangement that can secure multiple elongated objects simultaneously. This merging reduces the total number of separate fixing components needed, lowering material costs and assembly expenses while maintaining secure fixation through the collective action of all protrusions across the combined structure

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Each fixating member is designed as a universal component with multiple protrusions that can secure different types of elongated objects (cables, wires, ducts) in various configurations. This multi-functionality allows a single standardized component design to be used across multiple assembly positions and object types, reducing manufacturing complexity and assembly costs while ensuring reliable secure fixation through the adaptable protrusion geometry

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If more elongated objects are added to vehicles, then system functionality increases, but space for arranging objects becomes limited

Engineering Contradiction:

Improvesystem functionalityVSAvoidavailable space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The fixating members are designed with protrusions that nest into gaps between adjacent elongated objects, creating a compact nested arrangement where objects are tightly packed together. This nesting configuration maximizes the use of available space by eliminating wasted gaps, allowing increased system functionality with more objects while minimizing the total area occupied by the fixed arrangement

Inventive Principle:

Principle #7Nested doll (Nesting)

4Reliability

If elongated objects are securely fixedated, then functionality is maintained, but removal during service becomes difficult

Engineering Contradiction:

Improvefunctional stabilityVSAvoidremoval ease

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The fixing arrangement employs a dynamic design where protrusions can be easily disengaged from gaps by applying a simple releasing force or movement to the fixating members. This dynamic mechanism allows the objects to be firmly held during operation (maintaining functional stability) while enabling quick and easy removal during service by simply reversing the engagement action, without requiring complex tools or procedures

Inventive Principle:

Principle #15Dynamics

AI summary

A fixing arrangement (10, 10') is disclosed configured to fixate a number of elongated objects (5, 5') relative to a vehicle (20). The fixing arrangement (10, 10') comprising a first fixating member (1, 1') comprising a plurality of first protrusions (f1 - f5) and a second fixating member (2, 2') comprising a plurality of second protrusions (s1 - s5). A number of first protrusions (f1, f3, f4) are configured to protrude into a gap (4) between two adjacent second protrusions (s1 - s5) to fixate an elongated object (5, 5') between a tip (T1) of the first protrusion (f1, f3, f4) and the two adjacent second protrusions (s1 - s5). Similarly, a number of second protrusions (s1, s3, s4) are configured to protrude into a gap (4') between two adjacent first protrusions (f1 - f4) to fixate an elongated object (5, 5'). The present disclosure further relates to a vehicle (20) comprising a fixing arrangement (10, 10').
