Pre-Filled Stain Removal Accessory for Safe Bleach Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stain removal methods require users to manually fill and handle liquid bleach, which is inconvenient and poses safety risks.
Innovation Solution
A stain removal accessory with a pre-filled container of bleach chemical, such as sodium percarbonate, that is designed to be used with a stain removal device, allowing for convenient and safe application directly onto stained areas without the need for user handling of bleach.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually fill and handle liquid bleach, then stain removal can be achieved, but convenience deteriorates and safety risks increase
Solution Approach 1:
The bleach chemical is pre-filled into the container during manufacturing, eliminating the need for users to handle or fill the chemical themselves. This preliminary action resolves the contradiction by maintaining safety (users never handle bleach) while preserving convenience (the pre-filled container is ready to use immediately)
Solution Approach 2:
The container acts as an intermediary between the bleach chemical and the user. Instead of users directly handling bleach, they interact with the sealed container that contains the chemical, thereby eliminating safety risks while maintaining ease of operation through simple container attachment and usage
2Ease of operation
If users manually fill bleach containers, then stain removal functionality is achieved, but operation complexity increases
Solution Approach 1:
The container is pre-filled with bleach chemical during manufacturing before reaching the user. This eliminates the complex filling operation from the user's workflow, simplifying the operation to merely attaching the pre-filled container to the stain removal device
Solution Approach 2:
The filling operation is extracted from the user's workflow and performed during manufacturing. By separating the filling step from the usage step, the device complexity for the user is reduced to simple attachment and application, while the manufacturing process handles the complex filling operation
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
Enables efficient and safe stain removal by pre-loading the bleach chemical, eliminating the need for user handling and simplifying the process, while ensuring effective stain treatment and rinsing.
Implementation Method 1
The container (400) is adapted to receive water from the stain removal device in order to dissolve the stain removing material
Implementation Method 2
dissolve the stain removing material being inside

AI summary
A stain removal accessory that cooperates with a stain removal device for treating a stained area is attached to a front head of the stain removal device, namely to a water and/or steam venting face of the stain removal device. The stain removal accessory includes a container like a pad, a cartridge, a sachet, or a capsule provided with a permeable external layer, for containing a stain removing material, and a flap-flip piece including a holder for holding the container, whereby the stain removal accessory is adapted to release the stain removing material on the stained area when cooperating with the stain removal device by facing a flow of water and/or steam generated by the stain removal device.
