Dishwasher Detergent Dispenser on Delivery Line for Mechanical Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwashers face increased costs and malfunction risks due to the use of electrical components for detergent delivery, and the design of detergent boxes on the door reduces loading volume, making them inconvenient to use.
Innovation Solution
A dishwasher with a detergent dispenser mechanism on the delivery line, featuring a piston that moves to push a frame with detergent boxes, allowing mechanical control of detergent delivery into the washing tub, and includes a movement mechanism with positions to ensure timely detergent mixing with water, along with abutments for leakproofing and user-extendable features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical components (solenoid coil or thermal pusher/puller) are used to open the detergent box lid, then the detergent can be delivered into the washing tub at the correct time, but the costs and the risk of malfunction increase
Solution Approach 1:
The patent replaces electrical components (solenoid coil or thermal pusher/puller) with a purely mechanical piston-cam mechanism. The piston is driven by water pressure from the delivery line to mechanically open the lid and trigger detergent delivery, eliminating electrical components while maintaining reliable timed delivery functionality
Solution Approach 2:
The patent utilizes hydraulic pressure from the water delivery line to drive the piston mechanism. The water pressure automatically actuates the mechanical components to open the lid and deliver detergent at the appropriate time during the washing cycle, replacing electrical actuation with hydraulic power
2Ease of operation
If the detergent box is disposed on the door facing the rack, then the detergent can be easily accessed, but the rack area decreases when the size of the detergent box is increased
Solution Approach 1:
The patent relocates the detergent dispenser from the vertical door surface to the horizontal delivery line. This spatial repositioning allows the detergent box to be integrated into the water flow path without occupying rack space, effectively moving the function to a different dimension where it no longer competes for loading volume
Solution Approach 2:
The patent integrates the detergent dispenser directly into the delivery line structure. The detergent box, piston, and lid mechanism are combined with the water delivery pathway, creating a unified system that eliminates the need for separate door-mounted detergent storage while maintaining functional accessibility
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
The mechanical control of detergent delivery reduces costs and malfunctions, increases loading volume by eliminating the need for electrical components, and ensures efficient detergent mixing, enhancing user convenience and washing efficiency.
Implementation Method 1
the piston moves towards the detergent dispenser with the pressure of the water flowing through the delivery line
