Solution Overview

Problem

Existing retail display fixtures with sliding doors often suffer from misalignment issues and are difficult to assemble, which can impact their functionality and efficiency.

Innovation Solution

The bypass door assembly includes two or more door panels with wheel components and adjustable drop rails, coupled with a first and second coupling member that includes tracks and guides to facilitate smooth sliding and alignment of the doors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional sliding doors are used in retail display fixtures, then the doors can conceal and display products, but the doors become misaligned with tracks and are difficult to assemble

Engineering Contradiction:

Improvedoor alignmentVSAvoidassembly difficulty

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The door assembly is segmented into multiple components: door panels with wheel components, coupling members with tracks, splice bars for track sections, and adjustable drop rails. This segmentation allows each component to be manufactured and assembled separately, improving ease of manufacture while maintaining reliable door alignment through precise track-wheel interfaces

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wheel components are pre-installed on the door panels during manufacturing, and the tracks are prepared with splice bars for alignment. This preliminary action ensures that when the doors are assembled in the field, the alignment features are already in place, reducing assembly difficulty and ensuring reliable door alignment without requiring complex field adjustments

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If sliding doors are used to conceal products, then product visibility can be controlled, but the doors become misaligned with tracks

Engineering Contradiction:

Improveproduct visibility controlVSAvoidtrack alignment

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The wheel components act as intermediaries between the door panels and the tracks. These wheels are precisely manufactured to fit within the track grooves, providing a reliable mechanical interface that maintains track alignment while allowing the doors to slide smoothly for product visibility control

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The door system uses movable wheel components that can adjust to minor variations in track positioning while maintaining proper alignment. The wheels rotate within the track grooves, providing dynamic adaptation that maintains manufacturing precision even as the doors move between open and closed positions for product display

Inventive Principle:

Principle #15Dynamics

AI summary

A bypass door assembly for a retail display fixture has two or more door panels each with a wheel assembly coupled to a top of the door panel and an adjustable drop rail that extends from a bottom of the door panel, a first coupling member having a first track and a second track for receiving the respective wheel assemblies of a first door panel and a second door panel, and a second coupling member having one or more guides for receiving the adjustable drop rail of one of the two or more door panels.
