Snap-In Front Stop for Retail Merchandise Tray Assembly Ease
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current retail merchandise tray assemblies are complicated to assemble due to the requirement of locating the front stop before securing the frame members, which increases assembly difficulty and complexity.
Innovation Solution
The design includes a front stop mounted to upstanding wall portions with resiliently attached mounting tabs and protrusions, allowing for easier assembly by reducing the force required to align and secure the front stop, and featuring cantilevered portions that offset and flex to facilitate mounting without requiring precise initial placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the front stop is mounted between frame members before securing them, then the front stop can be positioned correctly, but the assembly process becomes more difficult and complex
Solution Approach 1:
The mounting tabs are pre-formed on the front stop with resilient properties, allowing the front stop to be snapped onto the frame members after they are positioned. This preliminary preparation of the mounting features eliminates the need to hold and position the front stop during frame assembly, resolving the contradiction between positioning accuracy and assembly ease
Solution Approach 2:
The mounting tabs are designed with resilient properties that allow them to flex during assembly and then lock into place on the frame members. This change in physical state from flexible during assembly to rigid in operation enables easy assembly while maintaining precise positioning of the front stop
2Ease of manufacture
If the front stop is mounted to hinge arrangements, then assembly is easier, but the arrangement becomes more complex
Solution Approach 1:
The invention extracts the hinge function from a separate hinge arrangement and integrates it directly into the mounting tabs of the front stop. The resilient tabs themselves perform the hinge-like function of allowing angular adjustment during assembly, eliminating the need for separate hinge mechanisms and reducing overall device complexity while maintaining assembly ease
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
This design simplifies the assembly process by reducing the force needed for mounting the front stop and preventing angular rotation, making it easier to attach the front stop to the frame without the need for precise initial placement, thus streamlining the assembly of retail merchandise trays.
Implementation Method 1
The first mounting tab is resiliently attached to the upright member such that a lesser amount of force is required to laterally displace the first mounting tab parallel to the second axis relative to the upright member
