Shelf Pusher Track With Living Hinge for Adjustable Merchandising
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current forward feed devices and divider walls in shelving systems are complex and expensive to manufacture, lack adaptability for wide products, and are difficult to adjust without unloading merchandise, leading to frictional challenges and inadvertent movement during use.
Innovation Solution
A merchandising system featuring a solid, thermoplastic pusher track with a flexible rear end and a nose section connected by a living hinge, allowing for easy mounting and dismounting without unloading products, and adjustable dividers that can be selectively locked or moved on a rail, accommodating various merchandise sizes and preventing unintended movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If complex injection molded plastic tracks are used for forward feed devices, then the tracks can be manufactured with sufficient rigidity to resist stresses and strains, but the manufacturing cost and die complexity increase significantly
Solution Approach 1:
The track is constructed as a composite structure combining a rigid plastic body with an integrated flexible nose section. The rigid body provides the necessary strength to resist stresses and strains during operation, while the flexible nose section (made from the same thermoplastic material) provides the needed flexibility for engagement and disengagement without requiring complex separate components or expensive molding dies.
2Ease of manufacture
If single-width divider walls are used in pusher systems, then the structure is simple to manufacture, but the system cannot accommodate thin merchandise items such as tooth brushes or small bottles
Solution Approach 1:
The divider wall is designed with a movable characteristic, allowing it to be adjusted to different positions and orientations. This enables the same simple single-width divider structure to adapt to various merchandise sizes and configurations, including thin items like tooth brushes and small bottles, without requiring multiple different divider designs.
3Stability of the object's composition
If forward feed devices are fixedly mounted to the front rail, then the spacing and positioning are stable, but the devices cannot be adjusted or repositioned without unloading all merchandise
Solution Approach 1:
The forward feed device incorporates a movable mounting mechanism that allows it to be repositioned along the front rail. The device can be moved to different locations, adjusted in orientation, and securely locked in place as needed. This dynamic mounting system enables adjustment and repositioning without requiring the unloading of merchandise, while still providing stable positioning when locked in place.
4Ease of operation
If dividers and tracks are slidably mounted on the front rail, then adjustment is easy, but inadvertent movement occurs during normal use
Solution Approach 1:
The mounting system combines movable and lockable characteristics. The dividers and tracks can be easily moved and repositioned along the front rail when adjustment is needed, but include locking mechanisms that securely fix them in place during normal operation. This prevents inadvertent movement while maintaining ease of adjustment when required.
5Device complexity
If the nose section is rigidly connected to the track body, then the structure is simple, but the nose cannot flex to engage and disengage from the mounting member
Solution Approach 1:
The nose section is designed as a flexible extension of the track body, made from the same thermoplastic material. This flexible nose can bend and flex to engage with and disengage from the mounting member (front rail) without requiring complex separate components, hinges, or attachment mechanisms. The flexibility is inherent in the molded structure itself.
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 system reduces manufacturing costs, enhances adaptability for different product sizes, and allows for easy adjustment and secure locking of tracks and dividers, improving operational efficiency and preventing product displacement during normal activities.
Implementation Method 1
A nose section (456) flexibly mounted to the front end (470) of the body (442). In one embodiment, the nose section is connected to the body by a hinge (464).
Implementation Method 2
The nose (456) contacts a wall of the elongated mounting member (410) to retard relative movement between the cooperating member (440) and the elongated mounting member (410).

AI summary
A merchandising system includes an elongated mounting member that is selectively securable to a front portion of an associated shelf. A cooperating member is received on the mounting member. The cooperating member extends rearwardly over the associated shelf. The cooperating member includes an elongated body having a front end and a rear end and a nose extending from the front end. A hinge connects the nose to the front end. The nose contacts a wall of the elongated mounting member to retard relative movement between the cooperating member and the elongated mounting member.
