Solution Overview

Problem

Existing shower enclosure attachment methods are inefficient, requiring multiple tools, leading to prolonged assembly times and poor waterproof performance, with exposed connections that are aesthetically unpleasing and prone to damage.

Innovation Solution

A profile attachment system featuring embedded main bodies with locking components and dovetail grooves, allowing for rapid assembly, enhanced stress bearing, and improved waterproofing by hiding the attachment within the profile, utilizing sliding grooves and embedded protrusions for secure and balanced connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If plastic fasteners are used for attachment, then assembly speed is improved, but appearance quality deteriorates and waterproof performance worsens

Engineering Contradiction:

Improveassembly speedVSAvoidappearance quality

Core Design Contradiction:

ProductivityVSShape

Solution Approach 1:

The invention extracts the attachment function from visible external fasteners and relocates it to embedded attachment main bodies hidden within the profile cross-sections. The attachment main bodies are embedded in the inner cavities of the profiles, making them invisible from the outside, thus eliminating the ugly appearance of exposed plastic fasteners while maintaining rapid assembly capability through the embedded attachment mechanism.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The attachment main bodies are nested within the profiles by embedding them in the inner cavities of the profile cross-sections. The attachment main bodies are received within the profiles, with their outer surfaces abutting the inner surfaces of the profiles, creating a nested structure that hides the attachment components inside the profiles while maintaining structural integrity and appearance quality.

If monorail fitting connection is used, then assembly speed is improved, but connection stability deteriorates

Engineering Contradiction:

Improveassembly speedVSAvoidconnection stability

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The attachment system is segmented into multiple functional components: attachment main bodies embedded in profiles, locking components with locking protrusions and locking inserts, and sliding grooves with slide tables. This segmentation allows each component to perform its specific function efficiently while working together to achieve both rapid assembly and stable connection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The locking mechanism incorporates dynamic elements including sliding grooves that allow relative movement between attachment main bodies, and locking components that can transition between locked and unlocked states. The slide tables can move within the sliding grooves during assembly and under load, providing dynamic adjustment capability while maintaining connection stability through the locking protrusions and inserts.

Inventive Principle:

Principle #15Dynamics

AI summary

In order to eliminate defects of appearance and stress bearing performance in existing profile attaching structure, a profile attaching structure, profiles therein, and a profile attachment is disclosed. The profile attachment comprises an attachment main body I, an attachment main body II and a locking component for preventing detachment of the attachment main bodies. The profile comprises a first profile matched with the attachment main body I and a second profile matched with the attachment main body II. A first sliding groove and a slide table on the attachment main body I are matched with a second U-shaped opening and a first U-shaped opening on the first profile, respectively. The attachment main body I can be wrapped by the first profile. An embedded protrusion on the attachment main body II is matched with and embedded into an embedded cavity of the second profile. The attachment main body II is also provided with a first slide rail matched with the first sliding groove and a second slide rail matched with the slide table. The attachment main body I and the attachment main body II are locked and fastened by a locking component.
