Blind Lining Plate Mechanism for Rope-Free Manual Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blind control devices are complex, time-consuming, and costly, with safety hazards such as child safety risks and high production costs, particularly in the rope pulling/bead pulling type, necessitating a simpler and safer operation mechanism.
Innovation Solution
A device comprising a fixing frame and a lining plate with two usage states, allowing for easy manual raising and lowering of blinds without a pulling rope, featuring a baffle bar and baffle plates for secure connection and a rivet structure for rotational adjustment, enabling quick and safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rope pulling/bead pulling type is used to control blind, then the blind can be raised or lowered, but child safety hazards occur and it is easy to hang neck
Solution Approach 1:
The patent removes the rope pulling mechanism entirely and replaces it with a lining plate system that contacts the blind body directly. This extraction of the harmful rope element eliminates the safety hazards while maintaining the blind control function through a safer contact-based mechanism.
Solution Approach 2:
The lining plate is designed as a simple, inexpensive component that can be easily replaced if needed. This approach prioritizes safety and simplicity over durability, allowing the system to be cost-effective and safe for children without requiring expensive or complex mechanisms.
2Ease of operation
If rocker type or spring-driven type is used to control blind, then the blind can be raised or lowered, but production and manufacturing costs are relatively high
Solution Approach 1:
The patent employs a simple lining plate and fixing frame structure that is significantly cheaper to manufacture than rocker or spring-driven mechanisms. The design prioritizes cost-effectiveness by using basic mechanical components rather than expensive precision mechanisms.
Solution Approach 2:
The patent extracts complex mechanical components (rocker, spring) and replaces them with a simplified lining plate system. This removal of unnecessary complex elements directly reduces manufacturing costs while maintaining operational functionality.
3Ease of operation
If complex reel rolling methods are used to control blind, then the blind can be raised or lowered, but the parts and structures are relatively numerous and complex and the operation is complicated and time-consuming
Solution Approach 1:
The patent removes the entire reel and rope system, extracting the source of complexity. By eliminating these components and replacing them with a direct lining plate contact system, the device achieves simplicity in both structure and operation.
Solution Approach 2:
The patent merges the lining plate and fixing frame into a unified simple structure that performs all necessary functions. This consolidation eliminates the need for separate complex components like reels, ropes, and beads, reducing overall device complexity.

AI summary
Disclosed is a device for lowering and raising blind, which relates to the technical field of blind, wherein the device comprises a fixing frame and a lining plate, the fixing frame is used to connect with a blind body; the lining plate articulately connects with the fixing frame; the lining plate has a first usage state and a second usage state, in the first usage state, the blind body is raised, and the lining plate contacts with the blind body to prevent the blind body from being lowered; in the second usage state, the lining plate is located at each side of the blind body, and the blind body may be performed an lowering operation or a raising operation. The application is able to be manually lowered or raised through a cooperation of the lining plate and the fixing frame without a pulling rope.
