Solution Overview

Problem

Existing securing devices for vehicle parts require additional components for mounting, which complicates the assembly process and increases costs and logistics, as they are not versatile enough for multiple configurations.

Innovation Solution

Incorporating a flexible plastic strip or connecting member within the vehicle part during injection moulding, allowing the securing member to be integrated and easily positioned during assembly, eliminating the need for separate components and simplifying the production process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional mounting components are used to secure vehicle parts, then the securing function is achieved, but the assembly process becomes more complex and time-consuming

Engineering Contradiction:
Improvesecuring functionVSAvoidassembly process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the securing member and connecting member into a single integrated component that is injection-moulded together with the main body. This merging eliminates the need for separate mounting components and reduces assembly steps, directly resolving the contradiction between achieving reliable securing and simplifying the assembly process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated securing device serves multiple functions: it provides structural support, enables mounting to the vehicle body, and ensures proper positioning of the main body. This multi-functionality allows the same component to achieve securing reliability while reducing overall device complexity.

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

2Reliability

If additional mounting components are used, then the securing function is achieved, but assembly time and costs increase

Engineering Contradiction:
Improvesecuring functionVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By merging the securing member and connecting member into a single injection-moulded component, the patent eliminates multiple assembly operations. The securing function is maintained while assembly time is reduced, as the entire securing device is produced as one piece during the main body manufacturing process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The securing members are pre-integrated into the main body during injection moulding, before the actual assembly of the vehicle. This preliminary action ensures that no additional time is required during final assembly, directly improving productivity while maintaining securing reliability.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If separate securing members are used, then mounting flexibility is achieved, but logistics and handling become more complex

Engineering Contradiction:
Improvemounting configurationVSAvoidlogistics complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges all securing elements into the main body structure through injection moulding. This integration simplifies logistics by reducing the number of separate components that need to be managed, stored, and handled, while the design of the integrated securing members maintains the necessary mounting flexibility.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Securing device (3) for a vehicle part (1), in which the part (1) is made of plastic, obtained by injection moulding, in which the part (1) comprises a main body (2), and in which the securing device (3) comprises a securing member (31) and a connecting member (32) for connecting said securing member (31) to the main body (2), in which the main body (2) and the securing device (3) are obtained by means of the same injection moulding process and the connecting member (32) is elongate. This affords a securing device (3) in which it is not necessary to provide an additional mounting member, thereby optimizing the assembly process. It also simplifies the operation of placing said additional securing member in the bolt or the like provided on the vehicle body, as it is already incorporated and positioned close to the latter.
