Solution Overview

Problem

Existing cabinets are complex and time-consuming to assemble for end users due to the requirement of attaching side panels to top and bottom panels using screws and intervening brackets.

Innovation Solution

The cabinet design features rear connector elements on the side panels that connect to carrier element slots and front connector elements on the top panel that connect to the side panels, allowing for easy attachment and assembly by attaching side panels to carrier elements and connecting their front corners to the top and bottom panels, with optional U-shaped folds and sheet metal clips for additional stability and ease of assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If side panels are attached to top and bottom panels using screws and intervening brackets, then the cabinet structure is stable and strong, but the assembly process becomes complex and time-consuming

Engineering Contradiction:
Improvecabinet structure strengthVSAvoidassembly complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent removes the complex bracket system and intermediate fasteners from the assembly process. Instead, side panels are directly attached to the top and bottom panels using simple hook-shaped connector elements that engage with corresponding slots, eliminating unnecessary components while maintaining structural integrity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces simple slot and hook connector elements as intermediary features between the side panels and top/bottom panels. These minimalistic connectors replace complex brackets and multiple screws, providing a straightforward attachment mechanism that is both structurally sound and easy to assemble

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If side panels are attached using screws and brackets, then the cabinet has reliable structural integrity, but the assembly time increases

Engineering Contradiction:
Improvestructural integrityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The cabinet is divided into modular components (top panel, bottom panel, side panels) with standardized connector elements. Each side panel can be independently attached to the top and bottom panels using separate hook connectors, allowing for quick, step-by-step assembly without requiring complex pre-assembly or specialized tools

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hook-shaped connector elements on the side panels are designed to self-align and self-attach to the slots in the top and bottom panels. The hooks naturally engage with the slots through simple insertion and rotation movements, eliminating the need for precise alignment tools or complex fastening procedures, thereby significantly reducing assembly time while ensuring reliable structural integrity

Inventive Principle:
Principle #25Self-service

AI summary

The present disclosure relates to a cabinet adapted to be suspended from vertically oriented carrier elements (11, 13), provided with slots (15), The cabinet has a top (3) and bottom panels (5), as well as first and second side panels (7,9). The side panels comprise rear connector elements (31) for connecting to carrier element slots at the rear of the cabinet, and the top panel comprise connector elements (33) connecting the front corners of the top panel to the front end of a side panel. Thereby a cabinet can be redily assembled by an end user.
