Roller and insert plate-assisted roller securing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of roller blinds is challenging due to their bulkiness and weight, requiring joint efforts from at least two people to align and secure the posts with grooves, as existing securing methods are not applicable to roller blinds without a protruding shaft member.
Innovation Solution
An insert plate-assisted roller securing device that includes a wheel-shaped cover, an outer cover, and a bracket, with a supported portion and an insert plate, allowing a single person to easily and quickly secure the roller by engaging the protuberance with corresponding holes and forming a position-limiting space for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the posts and grooves are tightly engaged to prevent the roller blind from falling off, then the reliability is improved, but the ease of operation deteriorates because at least two people are required to align and insert the posts into the grooves
Solution Approach 1:
The patent introduces a bracket as an intermediary component that mediates between the roller blind and the mounting surface. The bracket includes a securing structure with a receiving space and a gap, allowing the roller blind to be secured without direct tight engagement between posts and grooves. This intermediary structure enables single-person installation while maintaining mounting security.
2Reliability
If the roller blind is made bulky and heavy to provide adequate coverage, then the reliability is improved, but the ease of operation deteriorates because it becomes difficult for a single person to hold and align the roller blind during installation
Solution Approach 1:
The patent segments the mounting system into separate components: the roller blind, the bracket, and the mounting surface. The bracket is designed with a receiving space and gap structure that can independently support the roller blind's weight. This segmentation allows the roller blind to maintain its bulky and heavy construction for adequate coverage while the bracket handles the support function, enabling single-person installation.
3Ease of operation
If the securing structure is designed with a gap smaller than the supported portion width, then the ease of operation is improved for quick insertion, but the reliability deteriorates without additional position limitation mechanisms
Solution Approach 1:
The patent extends the securing structure into another dimension by adding a position-limiting space that protrudes from the bracket. This position-limiting space works together with the gap to provide both quick insertion (through the gap) and stable positioning (through the position-limiting space). The supported portion of the roller blind engages with both the gap and the position-limiting space, achieving rapid mounting while ensuring reliable stability.

AI summary
A roller and an insert plate-assisted roller securing device are provided. The insert plate-assisted roller securing device includes a wheel-shaped cover, an outer cover, and a bracket. The outer cover has a supported portion with different widths in different directions, and the supported portion can be engaged in the bracket without separating from the bracket. As the outer cover can be coupled to the bracket along with the roller by a single person, installation of the roller is made easier and less time-consuming than before.
