Solution Overview

Problem

Existing goods display devices require significant time and effort to assemble, and they experience increased friction between products and frame rails due to the use of multiple single-column roller bases, which reduces work efficiency and product movement.

Innovation Solution

A roller-type goods display device with a roller stage composed of multiple unit columns, featuring a frame rail between these columns, end caps, and a zigzag arrangement of column ends to facilitate efficient assembly and minimize friction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If multiple single-column roller bases are connected to form a display device, then the display device can accommodate larger products, but the assembly time and work effort increase significantly

Engineering Contradiction:
Improvedisplay widthVSAvoidassembly time
Core Design Contradiction:
Area of moving objectVSLoss of time

Solution Approach 1:

The patent combines multiple columns into a single integrated roller base unit. Instead of connecting separate single-column roller bases, the invention creates one roller base that incorporates multiple columns (first column, second column, third column, fourth column) as unified structural components, thereby reducing the number of connection operations required during assembly.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The roller base is segmented into multiple independent columns (first column, second column, third column, fourth column) that can be manufactured separately and then assembled into a complete roller base unit. This segmentation allows for standardized production of column components while reducing the complexity of assembling multiple separate roller bases.

Inventive Principle:
Principle #1Segmentation

2Area of moving object

If multiple single-column roller bases are connected via frame rails, then the display device can be configured for larger products, but the friction between products and frame rails increases

Engineering Contradiction:
Improvedisplay widthVSAvoidfriction
Core Design Contradiction:
Area of moving objectVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and eliminates the frame rail component from the structure. Instead of using frame rails to connect multiple roller bases, the patent designs a roller base where columns are directly integrated into the base structure, removing the intermediate frame rail that caused friction between products and the connection structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the columns directly into the roller base structure, eliminating the need for separate frame rails. The first column, second column, third column, and fourth column are all integrated components of the roller base, thereby removing the frame rail interface that generated friction during product movement.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If multiple roller bases are connected one by one, then the display device can be manufactured, but the work efficiency decreases due to alignment requirements

Engineering Contradiction:
ImprovemanufacturabilityVSAvoidwork efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent combines multiple columns into a single roller base unit that can be manufactured as an integrated structure or pre-assembled module. This merging reduces the number of individual assembly operations from connecting multiple separate roller bases to simply installing complete roller base units, thereby improving work efficiency by eliminating repetitive alignment tasks.

Inventive Principle:
Principle #5Merging (Combining)
