Convertible Steam Appliance With Push-Actuated Pumping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional steam generating appliances are limited to specific functions and lack versatility in using the water pumping mechanism to generate steam for multiple tasks.
Innovation Solution
A steam appliance that can be converted from a steam iron to a steam brush or cleaner and a steam mop by adding attachments, utilizing a push-down feature on the handle to actuate a water pump for steam generation, allowing for multiple uses and easy conversion between modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a steam appliance is designed for a dedicated function (steam iron, steam mop, or steam brush), then it can perform that specific function effectively, but it cannot be used for other steam-related tasks
Solution Approach 1:
The patent applies universality by designing a single steam generator appliance that can perform multiple functions through interchangeable attachments. The base unit remains simple while attachments (sole plate for ironing, pole for mopping, frame for brushing) enable different uses, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The patent applies segmentation by dividing the steam appliance into a permanent base unit (steam generator) and removable attachments. This allows the core device to remain simple while functionality is expanded through separate, interchangeable components that attach as needed.
2Extent of automation
If water is pumped from reservoir to boiler by push-pull movement, then the pumping mechanism can be actuated by user movement, but the appliance requires manual actuation for each pumping cycle
Solution Approach 1:
The patent applies self-service by designing the pump actuator to be automatically depressed when the user pushes the appliance forward. The appliance serves itself by converting the user's natural pushing motion into pump activation, eliminating the need for separate manual pumping actions while maintaining ease of operation.
Solution Approach 2:
The patent applies preliminary action by positioning the pump actuator mechanism so that the forward pushing motion naturally depresses it before water needs to be pumped. This preliminary depression of the actuator during normal movement prepares the pumping action in advance, automating the process without requiring additional user effort.
3Adaptability or versatility
If attachments are added to convert between modes, then the appliance can be used for multiple tasks, but the conversion process requires assembly and disassembly steps
Solution Approach 1:
The patent applies segmentation by creating clearly defined attachment interfaces between the base unit and various modes (sole plate, pole, frame). Each attachment is a separate component that connects to standardized interfaces, making conversion straightforward through simple attachment and detachment without complex assembly steps.

AI summary
A steam appliance having a split handle with the upper part biased away from the handle base and an actuator for a water pump. When the appliance is pushed, the handle upper part is depressed and displaces a pump actuator to activate the pump. Use of a steam frame and steam towel allows an iron to be used as a steam cleaner. When a pole is mounted on the upper handle part, the appliance may be used as a steam mop that is activated by pushing the pole which depresses the handle to actuate the pump.
