Solution Overview

Problem

Existing motor vehicle rear masking devices have protruding anchors with aggressive angular surfaces, which complicate mass production and storage by risking damage during stacking and require complex assembly procedures.

Innovation Solution

The anchors are designed to be completely contained within the anchor hole, eliminating protrusion and angular surfaces, with a retaining lip and a flexible link system that ensures secure mounting without external protrusions, allowing for efficient stacking and simplified assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional protruding anchors with angular surfaces are used, then the anchoring function is achieved, but the shelves cannot be safely stacked during mass production and storage

Engineering Contradiction:
Improveanchoring functionVSAvoidstacking safety
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The anchor is completely contained within the anchoring orifice of the shelf, with its outer surface positioned between the upper and lower surfaces of the shelf. This nesting configuration eliminates protruding angular surfaces that could damage adjacent shelves during stacking, while the anchor retains its anchoring function through the link element connected to the shelf's anchoring orifice.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If traditional protruding anchors are used, then the anchoring function is achieved, but complex assembly procedures and precautions are required

Engineering Contradiction:
Improveanchoring functionVSAvoidassembly procedure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The anchor is completely contained within the anchoring orifice, eliminating the need for complex stacking precautions and assembly procedures. The contained design allows for simpler mass production and storage procedures compared to traditional protruding anchors that require careful handling to prevent damage.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of manufacture

If anchors are completely contained within the anchor hole, then stacking and storage is simplified, but the anchoring strength may be reduced

Engineering Contradiction:
Improvestacking efficiencyVSAvoidanchoring strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The anchor is completely contained within the anchoring orifice while maintaining anchoring strength through proper design of the link element and its connection to the shelf. The contained configuration enables safe stacking during mass production and storage without compromising the anchoring function, as the anchor remains effectively engaged within the orifice.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The device (12) has a plate (40) defining an anchoring orifice (58) that is opened in one of an upper surface (50) and a lower surface (52) of the plate. A connecting element (44) connects the plate and an opening frame of a vehicle. The connecting element comprises an anchor (80) fixed in the anchoring orifice and a flexible link (82) extending between the anchor and a free end (100). The anchor is fully contained in the anchoring orifice without being projected beyond the upper surface and the lower surface of the plate. Independent claims are also included for the following: (1) a rear assembly of a motor vehicle (2) a method for mounting a masking device.
