Multi-Dose Dishwasher Detergent Holder for Sequential Bleach-Enzyme Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic dishwashing products lack the ability to efficiently deliver multiple detergent compositions sequentially during a single operation, which can impact cleaning performance and user convenience.
Innovation Solution
A multi-dosing detergent delivery device that accommodates two different detergent compositions, including halogen bleach and enzymes with a bleach scavenger, and uses a thermally reactive element like a wax motor to deliver these compositions sequentially within the dishwashing machine, ensuring effective cleaning without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single detergent composition is delivered in each dishwashing operation, then the device construction is simple, but the cleaning performance is insufficient
Solution Approach 1:
The detergent holder is divided into separate compartments for different detergent compositions (e.g., enzyme compartment, bleach compartment, rinse aid compartment). Each compartment can be independently filled and delivered at appropriate times during the dishwashing cycle, enabling multiple detergent functions without requiring a complex multi-device system.
Solution Approach 2:
The detergent holder is designed to accommodate multiple types of detergent compositions simultaneously, making it a multi-functional component that can deliver enzymes, bleach, and rinse aid from a single device. This universal design simplifies the overall system while maintaining comprehensive cleaning capabilities.
2Reliability
If multiple detergent compositions are delivered simultaneously, then cleaning performance improves, but harmful interactions between compositions occur
Solution Approach 1:
Different detergent compositions are physically separated into distinct compartments within the detergent holder. The halogen bleach, enzymes, and rinse aid are stored in separate sections, preventing premature contact and harmful chemical reactions while allowing each composition to be delivered at the optimal time during the wash cycle.
Solution Approach 2:
The detergent compositions are pre-positioned in their respective compartments before the dishwashing operation begins. This preliminary arrangement ensures that each composition is ready for delivery at the correct moment without requiring complex real-time mixing or transfer mechanisms, thereby avoiding harmful interactions.
3Ease of operation
If a multi-dosing detergent delivery device is implemented, then convenience and cleaning performance improve, but the device occupies more space in the dishwasher
Solution Approach 1:
The detergent holder is designed with a compact nested structure where multiple compartments are arranged concentrically or in space-efficient configurations. The actuating mechanism is integrated within the holder body, and the entire assembly fits into the existing detergent dispenser space of the dishwasher, minimizing additional space requirements while maintaining multi-dosing functionality.
Solution Approach 2:
The detergent holder utilizes vertical and radial dimensions efficiently, with compartments arranged in a three-dimensional configuration that maximizes space utilization. The actuating mechanism employs compact linear or rotational motion within the available space, transforming the delivery action into a space-efficient operation that does not require excessive horizontal space in the dishwasher.
