Solution Overview

Problem

Existing temperature-controlled display devices lack flexibility to convert between full-service and self-service modes, limiting merchants' ability to adapt to different operational needs.

Innovation Solution

A convertible temperature-controlled display case with a movable front panel that pivots between a deployed position for full-service mode and a stowed position for self-service mode, allowing for back-side access during full-service and front-side access during self-service, with adaptable refrigeration systems to optimize airflow and temperature control in each mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a closed front is used in full-service refrigerated display cases, then temperature control is improved, but customer accessibility is worsened

Engineering Contradiction:
Improvetemperature controlVSAvoidcustomer accessibility
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The front panel is made movable between a closed position (for temperature control in full-service mode) and an open position (for customer accessibility in self-service mode). The linkage mechanism enables the front panel to dynamically transition between these positions, allowing the case to adapt its accessibility characteristics based on operational needs while maintaining temperature control when closed.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If an open front is used in self-service refrigerated cases, then customer accessibility is improved, but temperature control is worsened

Engineering Contradiction:
Improvecustomer accessibilityVSAvoidtemperature control
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The front panel transitions to an open position during self-service mode, allowing customers direct access to products. The linkage mechanism enables smooth movement to this open configuration, and the refrigeration system adapts its airflow patterns to maintain temperature control despite the open front configuration.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a movable front panel linkage mechanism is added to enable mode conversion, then adaptability is improved, but device complexity is worsened

Engineering Contradiction:
Improvemode conversion capabilityVSAvoidlinkage mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The linkage mechanism serves multiple functions: it supports the front panel in the closed position, enables smooth transition to the open position, and can be integrated with the refrigeration system control. This multi-functionality reduces the need for separate mechanisms for each function, thereby limiting the increase in overall device complexity despite the added adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A temperature-controlled display case is convertible between a full-service mode and a self-service mode and defines a temperature-controlled space therein. A base has a back side and a front side and supports temperature-controlled food products within the temperature-controlled space. A back frame is coupled adjacent to the back side of the base and provides one or more openings for back-side access to the food products during the full-service mode. A top frame is supported by the back frame and a linkage has one end pivotally coupled to the top frame. A front panel has a top portion pivotally coupled to the linkage and is movable between a deployed position for the full-service mode with the front panel adjacent to the front of the base, and a stowed position for the self-service mode with the front panel disposed atop the top frame to provide front-side access to the food products.
