Appliance Drawer Unitary Bracket Assembly to Reduce Part Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage drawers for oven appliances require significant time and labor for assembly due to a high part count and specialized techniques, making them inefficient and costly.
Innovation Solution
A storage drawer design featuring a drawer body and outer panel connected by seamless, unitary brackets that include a liner, spacer, and wedge member, reducing the part count and simplifying assembly by using a single, integrated piece for each bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional drawer assembly methods are used with multiple separate parts (drawer body, liner, outer panel, wedges, screws), then the drawer structure is stable and functional, but the assembly time and labor requirements increase significantly
Solution Approach 1:
The patent combines the liner member, spacer member, and wedge member into a single seamless unitary bracket. This merging of three separate components into one integrated piece directly reduces the total part count and eliminates the need for multiple fastening operations, thereby significantly reducing assembly time and labor while maintaining the structural functions of each individual component
Solution Approach 2:
The unitary bracket performs multiple functions simultaneously: the liner member provides structural support and alignment, the spacer member maintains proper spacing between components, and the wedge member secures the assembly. By integrating these three functional elements into a single multi-functional bracket, the design reduces complexity without sacrificing stability or functionality
2Ease of manufacture
If multiple separate components are used to construct the drawer brackets, then each component can be optimized for its specific function, but the overall assembly process becomes more complex and requires specialized equipment
Solution Approach 1:
The patent merges the liner, spacer, and wedge members into a single seamless unitary bracket that can be manufactured as one piece. This eliminates the need for complex multi-step assembly processes involving multiple fasteners and specialized pressing equipment, while still providing the structural optimization benefits of having distinct functional zones within the bracket
3Device complexity
If conventional multi-part brackets are used, then each part can be independently manufactured and replaced, but the total number of parts increases assembly time and cost
Solution Approach 1:
The patent combines three separate bracket components into one seamless unitary bracket, reducing the part count from three to one. This single integrated component eliminates the time required to assemble multiple parts with fasteners, while the internal structure of the unitary bracket maintains the functional distinctions of the original separate components

AI summary
An appliance includes a cabinet, a drawer cavity defined in the cabinet, and a drawer slidably mounted within the drawer cavity. The drawer is slidable between a closed position and an open position. The appliance also includes an outer panel enclosing a front side of the drawer body. A storage volume of the drawer is defined between the drawer body and the outer panel. A first bracket is directly connected to the drawer body at a first side of the drawer body and directly connected to the outer panel at a first side of the outer panel. A second bracket is directly connected to the drawer body at a second side of the drawer body opposite the first side of the drawer body, the second bracket is also directly connected to the outer panel at a second side of the outer panel opposite the first side of the outer panel.
