Doorstop Conduit and Curtain Assembly for Hose Access Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional professional carpet cleaning methods require hoses to enter homes through open doors, leading to issues like insect infestation, energy loss, and safety concerns due to the open door, with no existing accessory effectively blocking the door opening during cleaning.
Innovation Solution
A carpet cleaning accessory device featuring a doorstop with holes and a conduit for hoses, combined with a flexible cloth and clamping mechanism to block the door opening, allowing hoses to pass through while keeping the interior isolated from external hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the door is opened to allow cleaning hoses to enter the structure, then carpet cleaning can be performed, but the structure becomes vulnerable to insects, pets, children entering or escaping, energy loss, and exposure to outdoor air quality issues
Solution Approach 1:
The device segments the door opening into two functional zones: a lower section occupied by the doorstop with conduit for hose passage, and an upper section blocked by the flexible cloth barrier. This segmentation allows selective access - hoses can pass through the lower section while the upper section maintains environmental isolation, resolving the contradiction between enabling cleaning access and preventing harmful factors from entering.
Solution Approach 2:
The flexible cloth acts as an intermediary element between the interior space and the door opening. It provides a semi-permeable barrier that allows air and vapor transmission while blocking insects, pets, and direct outdoor air exposure. This intermediary solution enables the door to remain functionally open for hose access while maintaining environmental protection, thus resolving the contradiction between productivity and harmful factor exposure.
2Object-affected harmful factors
If the door remains closed to maintain environmental isolation, then energy loss and insect entry are prevented, but cleaning hoses cannot access the interior of the structure
Solution Approach 1:
The doorstop device segments the door assembly into functional zones: the lower portion accommodates the conduit for hose passage, while the upper portion maintains closure with the flexible cloth barrier. This segmentation enables simultaneous achievement of environmental isolation and hose access, resolving the contradiction between preventing harmful factors and enabling operational access.
Solution Approach 2:
The conduit is nested within the doorstop structure, creating a protected pathway for hoses through the door assembly. This nesting arrangement allows hoses to pass through the doorstop's conduit openings without compromising the door's closure function, thus enabling hose access while maintaining environmental isolation and resolving the contradiction between ease of operation and harmful factor prevention.
3Object-affected harmful factors
If a rigid barrier is used to block the door opening, then environmental isolation is achieved, but the device becomes difficult to transport and set up by a single person
Solution Approach 1:
The flexible cloth barrier replaces rigid blocking materials with a flexible, lightweight film that can be easily manipulated, transported, and installed by a single person. This flexible barrier maintains environmental isolation functionality while dramatically improving portability and ease of setup, thus resolving the contradiction between harmful factor prevention and weight/portability concerns.
Solution Approach 2:
The flexible cloth barrier introduces dynamic adaptability to the door blocking function. Unlike rigid barriers that require precise fitting and heavy construction, the flexible cloth can dynamically conform to the door opening shape and be easily adjusted or removed. This dynamic property enables effective environmental isolation while maintaining lightweight construction that is easy to transport and set up, resolving the contradiction between isolation effectiveness and portability.

AI summary
A carpet cleaning accessory device is provided. The carpet cleaning accessory device comprises an aperture stop configured to fit between an aperture frame and an aperture gate where the aperture stop has at least a first hole and a second hole. The device also includes a conduit having at least a first opening and a second opening, where the conduit is secured inside the aperture stop such that the first opening couples with the first hole and the second opening couples with the second hole. A curtain adapted to couple to the aperture frame and the aperture gate using a coupling assembly is also included to substantially block an opening between the aperture gate and the aperture frame.
