Solution Overview
Problem
Existing ceiling ventilation devices are not compact, stable, or easy to assemble, as they often require extensive space and complex assembly processes.
Innovation Solution
A device featuring tubular profiles connected to a bed frame with spring elements for easy assembly and folding, utilizing a traverse with pivoted tube profiles and a spring band for elastic loading, allowing for quick setup and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a pantograph-like frame with telescopic rods is used for ceiling ventilation, then the device can be extended to provide ventilation, but it takes up a lot of space and is not stable after assembly
Solution Approach 1:
The patent implements nesting by placing one tubular profile inside another tubular profile. The inner tubular profile is inserted into the outer tubular profile, creating a compact nested structure that reduces volume while maintaining stability through the interconnected design.
Solution Approach 2:
The patent applies preliminary action through pre-assembled units where the tubular profiles are already connected to the bed frame and ceiling support before deployment. This pre-assembly ensures stability is built-in from the start, eliminating the need for complex on-site assembly while maintaining a compact form.
2Ease of manufacture
If a rectangular framework formed by rods is used to hold clothes, then the structure can support items, but it takes up a lot of space and requires assembly each time
Solution Approach 1:
The framework is designed so that tubular profiles nest within each other when not in use, creating a compact storage configuration. The nesting allows the structure to be collapsed into a small volume while maintaining ease of deployment through the self-supporting nested design.
Solution Approach 2:
The framework components are pre-assembled into integrated units before delivery, eliminating the need for complex assembly at the point of use. The pre-assembled units can be quickly deployed and stored without requiring repeated assembly and disassembly operations.
3Ease of operation
If a collapsible framework is used for clothes storage, then the structure can be folded, but the thickness of the collapsed scaffold is important as the beams face each other
Solution Approach 1:
The patent achieves compact folding by nesting tubular profiles within each other, where inner profiles are inserted into outer profiles. This nesting arrangement minimizes the collapsed thickness significantly compared to traditional folding where beams face each other, creating a sleek compact form.
Solution Approach 2:
Instead of folding beams outward where they face each other, the patent inverts the approach by having beams nest within each other. This inverted nesting configuration reduces the collapsed dimension while maintaining ease of operation for deployment and storage.
4Adaptability or versatility
If an extendable structure is used for balcony clothes attachment, then the structure can be extended, but it is not collapsible and requires attachment to balcony
Solution Approach 1:
The patent implements dynamic functionality where the tubular profiles can be extended or retracted relative to each other. The nested tubular structure allows for adjustable extension while maintaining the ability to collapse completely, providing both adaptability and collapsibility through a unified dynamic design.
