Trackless Shelf Pusher Mechanism to Prevent Product Tipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing merchandising systems face issues with product placement on shelves, as inclined trays and pusher systems can become obstructed by debris or sticky substances, leading to product tipping and binding, which hinders the efficient display and accessibility of products.
Innovation Solution
A trackless pusher mechanism that includes a pusher paddle and a coiled spring, where the spring is positioned across the pusher floor or divider, preventing the paddle from tipping and ensuring proper product movement, and dividers that can be easily repositioned for replanogramming, using a system without tracks or guides to maintain product alignment and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a trackless pusher mechanism is used, then the system eliminates track obstruction by debris and sticky substances, but the pusher paddle may tip or bend backwards causing binding
Solution Approach 1:
The pusher mechanism is divided into separate functional components: the pusher paddle for product contact, the floor for structural support, and the coiled spring for biasing force. This segmentation allows each component to be optimized independently - the floor provides stable mounting points for the spring while the paddle remains free to move without track constraints
Solution Approach 2:
The coiled spring acts as an intermediary element between the floor and the pusher paddle, providing the necessary biasing force while allowing for mechanical flexibility. The spring absorbs lateral forces and prevents the paddle from tipping or bending backwards by maintaining constant contact pressure without rigid constraints
2Ease of operation
If known pusher systems with tracks are used, then the pusher mechanism is guided and stable, but the track becomes obstructed with dirt or sticky materials hindering proper operation
Solution Approach 1:
The track component is completely removed from the system. Instead of guiding the pusher paddle through a track, the mechanism uses the floor surface and coiled spring arrangement to provide guidance and stability. This extraction eliminates the track obstruction problem while maintaining necessary control over pusher movement
Solution Approach 2:
The floor surface serves multiple functions: it provides the mounting base for the coiled spring, guides the pusher paddle movement through its geometry, and eliminates the need for separate track structures. The system uses its own structural elements rather than requiring additional guiding components
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
The trackless pusher mechanism effectively keeps products aligned and moving towards the front of the shelf, preventing tipping and obstruction, while allowing for easy adjustment and maintenance, ensuring continuous product visibility and accessibility.
Implementation Method 1
A flat coiled spring or other biasing element can be operatively connected behind the pusher paddle and extend across the floor of the pusher mechanism and to the front of the shelf
Implementation Method 2
The present invention provides a trackless pusher system that works with gravity-fed merchandise systems
