Laundry Pedestal Drawer with Stepped Compartments for User Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Front-loading laundry appliances are often installed on pedestals that raise them above the floor, providing storage and easier access, but existing solutions lack a practical and safe method for users to climb up to the appliance, especially considering varying user heights and the need for accessible storage compartments.
Innovation Solution
A laundry pedestal with a drawer that includes two vertically offset compartments, functioning as steps, allowing users to ascend and descend safely, while also providing storage and adjustable height options through a slide or hinge mechanism, supported by structural elements for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the appliance is raised above the floor on a pedestal, then storage space is provided and appliance access is improved, but users lack a safe and practical method to climb up to the appliance
Solution Approach 1:
The drawer is designed to serve dual functions: storage compartment and climbing steps. The first and second compartments function as steps when the drawer is extended, allowing users to climb up to the appliance, while also providing storage space when closed. This eliminates the need for separate climbing mechanisms while maintaining storage functionality.
Solution Approach 2:
The drawer structure itself provides the climbing function without requiring additional external components. The compartments and covers of the drawer are configured to support user weight and facilitate climbing, making the storage unit serve its own auxiliary function of providing access steps.
2Adaptability or versatility
If a single-height drawer is used, then storage is provided, but it cannot serve as effective climbing steps for users of different heights
Solution Approach 1:
The drawer is divided into two compartments of different heights: a first compartment and a second compartment vertically offset above it. The second compartment has a greater height than the first compartment, creating a stepped configuration that accommodates users of different heights and provides ergonomic climbing surfaces.
Solution Approach 2:
The drawer employs asymmetric compartment heights rather than uniform dimensions. The second compartment is vertically offset and taller than the first compartment, creating an asymmetric structure that better fits human anatomy and provides effective steps for climbing, thereby improving adaptability to different user heights.
3Reliability
If the drawer is made sturdy to support user weight, then safety is improved, but the drawer becomes heavier and more difficult to move
Solution Approach 1:
The drawer is designed with movable components including slide mechanisms for extension and retraction, and hinge mechanisms for the covers. These dynamic elements allow the drawer to be lightweight for easy operation while maintaining structural integrity when extended to support user weight during climbing.
Solution Approach 2:
The drawer structure transitions between different structural states: when retracted, it is lightweight for easy movement; when extended, it assumes a load-bearing configuration that safely supports user weight. The slide and hinge mechanisms enable this parameter change, allowing the same structure to serve both mobility and safety requirements.

AI summary
A laundry pedestal for supporting a laundry treating appliance includes a cabinet having a top wall, opposing side walls, and a base, and a drawer configured to be moved between a retracted position and an extended position relative to the cabinet. The drawer includes a first compartment having a first cover and a second compartment, adjacent to the first compartment, and having a second cover. A height of the second compartment is greater than a height of the first compartment.
