Solution Overview

Problem

Existing luggage ring assemblies are time-consuming to install and visually unappealing due to their exposed mounting members, which serve no functional purpose other than as a visual distraction, and often require multiple parts and tools for assembly.

Innovation Solution

A luggage ring assembly with a concealable mounting member that engages with the back surface of a panel through a single aperture, allowing for hidden attachment and improved pulling strength, featuring a single-piece construction, bent portion for easy insertion, and a fixation system that secures the ring member without visible fasteners, reducing the number of installation parts and potential weak joints.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional mounting members are used, then the luggage ring can be securely attached to the panel, but the mounting member remains visible and creates a visual distraction

Engineering Contradiction:
Improveattachment simplicityVSAvoidvisual distraction
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The mounting member is extracted from the visible front surface and relocated to the rear surface of the panel. The ring member passes through the panel from the front, with the mounting member attached to the rear surface, effectively removing the visual distraction while maintaining secure attachment functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of mounting the ring directly on the front surface of the panel, the mounting member is inverted to the rear surface. This reversal of the mounting location eliminates the visual distraction while preserving the structural attachment function.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If multiple separate parts are used for mounting, then the attachment can be secured, but the installation becomes time-consuming and complex

Engineering Contradiction:
Improveattachment securityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The ring member and mounting member are combined into a single integrated unit. The mounting member is directly attached to the rear surface of the panel, eliminating the need for separate mounting brackets, fasteners, or additional components, thereby reducing installation time while maintaining secure attachment.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If multiple separate parts and tools are required for assembly, then the mounting can be secured, but the device complexity increases

Engineering Contradiction:
Improvemounting strengthVSAvoidnumber of parts
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The ring member and mounting member are merged into a single integrated component. The mounting member is directly affixed to the rear surface of the panel, eliminating the need for separate fasteners, brackets, or multiple assembly steps, thereby reducing device complexity while maintaining mounting strength.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If visible fasteners are used to secure the ring member, then the attachment is reliable, but the aesthetic appearance is compromised

Engineering Contradiction:
Improveattachment reliabilityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

All fasteners and mounting components are extracted from the visible front surface and relocated to the rear surface of the panel. The ring member passes through the panel, and the mounting member is secured on the back side, eliminating visible fasteners while maintaining attachment reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mounting mechanism is inverted from the front surface to the rear surface. Instead of visible fasteners on the front, the mounting member is secured on the back side of the panel, reversing the location of the attachment components to achieve both reliability and aesthetic appearance.

Inventive Principle:
Principle #13The other way round (Inversion)
