Folding Utility Cart With Locking Hinges and Integrated Supply Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding utility carts are inadequate for efficiently transporting and storing cleaning supplies, particularly in smaller settings where manual transport is time-consuming and supplies are not readily available when needed.
Innovation Solution
A collapsible utility cart with a lower frame, 360° caster wheels, a handle frame, pail frame, tray, and locking hinges that allows for easy deployment and folding, incorporating features like hooks, mounting clips, and a spray bottle tray for versatile storage and transportation of cleaning equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cleaning supplies are transported by hand in smaller buildings and homes, then the supplies can be moved to the cleaning task area, but it takes much time when arriving and leaving a site and the supplies are never at hand when needed
Solution Approach 1:
The cart is divided into multiple functional segments including a lower frame for structural support, a pail frame for holding cleaning solutions, a tray for smaller supplies, and a handle frame for maneuverability. This segmentation allows each component to be optimized for its specific function while working together as an integrated system for efficient cleaning operations
Solution Approach 2:
The cart serves multiple functions: it transports cleaning supplies, stores various cleaning products in dedicated compartments, provides a stable platform for mixing solutions, and can be easily folded for storage when not in use. The multi-functional design eliminates the need for separate tools and containers, consolidating all cleaning needs into one versatile unit
2Ease of operation
If a folding utility cart is designed with multiple storage compartments, trays and clips for versatile storage, then cleaning supplies can be organized and accessed easily, but the device complexity increases
Solution Approach 1:
The storage system is segmented into distinct compartments: a lower frame with cross members for structural support, a pail frame with horizontal members for holding large containers, a tray with apertures for spray bottles, and mounting clips for long-handled tools. Each segment is designed to hold specific types of cleaning supplies, enabling organized storage and quick access without creating a cluttered or overly complex structure
Solution Approach 2:
The cart employs a nested arrangement where the tray is positioned within the pail frame structure, mounting clips are attached to the handle frame, and various compartments are integrated into the overall frame design. This nesting approach maximizes storage capacity within the available space while maintaining a compact and manageable structure that does not appear overly complex
3Stability of the object's composition
If the cart uses locking hinges to maintain deployed configuration during use, then the cart remains stable for cleaning operations, but the ease of folding for storage and transport is reduced
Solution Approach 1:
The hinge system transitions between two dynamic states: during use, the locking mechanism engages to maintain a stable deployed configuration that prevents accidental folding; when storage or transport is needed, the locking mechanism can be easily released to allow the cart to fold flat. This dynamic design provides both stability during operation and ease of folding when needed
Solution Approach 2:
The locking hinges are designed to maintain the cart's deployed configuration automatically during cleaning operations, providing inherent stability without requiring constant user intervention. The hinges naturally resist folding forces through their locking mechanism, allowing the cart to serve itself in maintaining its operational shape while still permitting easy folding when the user intentionally releases the locks
