Adjustable Merchandise Pusher Tray for Freezer Loading Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pusher systems fail in harsh environments like commercial refrigerated cabinets or freezers due to ice buildup, mechanical failure, and difficulty in loading, especially with heavier items that cause shelving bending.
Innovation Solution
A merchandise pusher tray with adjustable dividers and load-bearing members featuring a stiffness region resistant to deflection, allowing for easy integration and loading in refrigerated environments, with a pusher mechanism that can be locked for single-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional pusher system is used in a commercial refrigerated cabinet or freezer, then the pusher system can operate in a harsh environment, but ice buildup causes mechanical failure and jamming
Solution Approach 1:
The patent applies hydrophobic coating to the pusher body and track surfaces to prevent ice adhesion. The harmful ice buildup is converted into a non-adhering substance that slides off easily, allowing the pusher system to reliably operate in refrigerated environments without mechanical failure
2Ease of operation
If the pusher body is pushed away from its resting position with one hand to load merchandise, then loading can be performed, but the operation becomes difficult and time-consuming especially at greater cabinet depths
Solution Approach 1:
The patent incorporates a spring-loaded pusher body that automatically returns to its forward position after being pushed back for loading. This dynamic mechanism eliminates the need for manual repositioning, allowing employees to load merchandise with one hand and automatically having the pusher body return to its operational position, significantly reducing loading time and effort
3Quantity of substance
If heavier items are placed on cantilevered shelving extensions, then the shelving can support the items, but bending occurs in the shelving which is problematic for pusher systems with moving components
Solution Approach 1:
The patent designs the pusher system with a rigid tracked structure that provides localized structural support beneath the merchandise. This tracked structure acts as a reinforcement beam, distributing the weight of heavy items and preventing cantilever bending in the shelving, while allowing the pusher mechanism to maintain its moving components without interference from shelving deformation
4Productivity
If multiple pusher bodies and tracks are arranged side by side along a shelf, then multiple rows of merchandise can be displayed, but the configuration is difficult to load and maintain in confined cabinet areas
Solution Approach 1:
The patent divides the pusher system into modular components: individual pusher bodies that can be independently loaded, separate track sections, and detachable divider elements. This segmentation allows employees to load and maintain each pusher unit independently in confined cabinet areas, improving ease of operation while maintaining high merchandise display capacity through multiple side-by-side units
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables reliable operation and easy loading of merchandise in refrigerated environments by preventing mechanical failure and bending, while allowing for aesthetically pleasing automatic front-facing of products.
Implementation Method 1
A spring is connected between the pusher body and a leading edge of the track. The spring acts to bias the pusher body forward along the track towards the leading edge thereof.
Implementation Method 2
each of the pair of load bearing members has a stiffness region and a support region, the stiffness region being more resistant to deflection under a loading than the support region

AI summary
A merchandise pusher tray is provided. The merchandise pusher tray includes a base structure. The base structure is configurable for bar or shelf mounting. The base structure includes a pair of load bearing members for supporting a floor of the base structure. The merchandise pusher tray also includes at least one divider mounted to and adjustable in a first direction relative to the base structure. The merchandise pusher tray also includes a pusher mounted to and movable in a second direction relative to the base structure. A locking arm is provided for locking the pusher in a locked position and automatically unlocking the pusher from the locked position upon the exertion of an actuation force against the locking arm.
