Solution Overview

Problem

Existing display racks for baked goods hinder customer visibility and ease of removal, as the removal chamber is typically located between the presentation chamber and the customer, making it difficult to access items, especially at the end of the presentation chamber, and complicates the removal of individual components.

Innovation Solution

The display rack design places the removal chamber to the side of the presentation chamber, allowing unobstructed visibility and easy access, with a transparent front cover, modular construction for easy cleaning, and a non-return mechanism that prevents items from being pushed back into the presentation chamber, using a scoop pusher with a concave scoop and triangular structure for efficient product handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the removal chamber is located between the presentation chamber and the customer, then the non-return function is achieved, but the customer visibility of products and ease of removal is hindered

Engineering Contradiction:
Improvenon-return functionVSAvoidease of removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent repositions the removal chamber from a front-facing location (between presentation chamber and customer) to a lateral position (to the side of presentation chamber). This spatial reconfiguration in another dimension allows the non-return function to be maintained while eliminating the obstruction to customer visibility and access. The removal opening is provided on the side of the removal chamber, enabling customers to easily access products without looking through the removal chamber.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the removal chamber is located in front of the presentation chamber, then the goods can be removed, but the customer has to look through the removal chamber to see goods in the presentation chamber

Engineering Contradiction:
Improveremoval capabilityVSAvoidproduct visibility
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent moves the removal chamber from the front (blocking the customer's view of the presentation chamber) to the side (lateral dimension). This dimensional change allows customers to view products in the presentation chamber through transparent front covers without obstruction, while still enabling easy removal of goods through the side-located removal opening.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the removal chamber is positioned to allow easy access, then removal is simplified, but accessing items at the end of the presentation chamber becomes difficult

Engineering Contradiction:
Improveremoval simplicityVSAvoidaccess distance
Core Design Contradiction:
Ease of operationVSLength of moving object

Solution Approach 1:

By positioning the removal chamber to the side of the presentation chamber rather than in front, the patent creates a lateral access path that is perpendicular to the length of the presentation chamber. This allows customers to access items at the end of the presentation chamber more easily, as they can approach from the side rather than having to reach through the entire length of the chamber from the front.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A display rack for the presentation and dispensing of products which have to be protected in a hygienic manner, in particular foodstuffs, to a customer. The display rack has a presentation chamber for storing and visually presenting the products, having a front side which faces a customer, a rear side which is remote from a customer as well as a left-hand side and a right-hand side. The display rack also has a removal chamber having a removal opening for the removal of products from the display rack. A non-return device is provided between the presentation chamber and the removal chamber, and is arranged on the right-hand and/or left-hand side of the presentation chamber. Two panes are arranged one above the other as front covers for the front sides of the presentation chambers to define a pusher opening in a width direction.
