Solution Overview

Problem

The existing motor vehicle front face air inlet shutter devices require a manual and costly process for attaching electrical wiring, increasing production costs due to the need for removable clips during assembly.

Innovation Solution

Incorporating a snap-fit fastening device integral with the support frame to secure electrical supply cables, eliminating the need for manual installation and allowing for pre-wired devices to be delivered directly to manufacturers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If removable clips are used to attach electrical wiring to the support frame, then the electrical wiring can be installed during assembly, but the production cost increases due to manual installation steps

Engineering Contradiction:
Improveease of wiring installationVSAvoidproduction cost
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent merges the cable fixing function directly into the support frame structure by integrating cable holders as integral parts of the frame. This eliminates the need for separate removable clips and their manual installation, thereby reducing production costs while maintaining ease of wiring installation. The cable holders are formed as one piece with the support frame, combining structural support and cable management functions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support frame with integral cable holders provides self-service by automatically guiding and securing electrical wiring during assembly. The cable holders are positioned to automatically receive and secure cables as the support frame is assembled, eliminating the need for separate manual clipping operations. This self-securing mechanism reduces labor requirements and production costs.

Inventive Principle:
Principle #25Self-service

2Ease of manufacture

If manual assembly of removable clips is required, then electrical wiring can be attached, but manufacturing time increases

Engineering Contradiction:
Improveease of wiring attachmentVSAvoidmanufacturing time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The cable holding function is merged into the support frame structure itself, with cable holders formed as integral parts during frame manufacturing. This eliminates the need for separate manual attachment steps, significantly reducing manufacturing time while maintaining ease of wiring attachment. The cable holders are pre-positioned and ready to receive cables during assembly.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cable holders are preliminarily formed as integral parts of the support frame during its manufacturing process, before the actual cable installation occurs. This preliminary preparation of the cable securing mechanism eliminates the need for time-consuming manual assembly steps during final installation, as the holders are already in place and ready to secure cables.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If integral snap-fit fastening devices are used in the support frame, then cable fixation is simplified, but the frame structure becomes more complex

Engineering Contradiction:
Improveassembly speedVSAvoidframe structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cable fixation function is merged into the support frame structure by forming cable holders as integral parts of the frame. This integration simplifies the overall assembly process and increases productivity, as the cable holders are automatically positioned during frame manufacturing. The structural complexity increase is minimal and localized to specific areas where cable securing is needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The snap-fit fastening devices are implemented locally at specific positions on the support frame where cable securing is required, rather than making the entire frame structure complex. This localized approach to adding fixation features maintains overall frame simplicity while providing the necessary cable securing functionality, balancing assembly speed with structural simplicity.

Inventive Principle:
Principle #3Local quality
