Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen wire regulation and control devices face challenges in easy installation and disassembly due to the need for drilling and screw assembly, and square positioning structures that are difficult to assemble and disassemble.
Innovation Solution
A screen wire regulation and control device with a structure comprising a wire regulation body and a fixing seat, where the fixing seat has a protruded portion and a fastener with a compression space, and the wire regulation body has concave portions that match the protrusions of the fixing seat, allowing for easy assembly and disassembly without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drilling and screw assembly are used to fix the housing on the frame, then the device can be securely installed, but the installation process becomes complex and requires technical personnel
Solution Approach 1:
The device is divided into separate modules: a cover assembly and a base assembly, each with integrated mounting features. The cover and base can be independently positioned and secured to the frame using positioning posts and socket holes, eliminating the need for a separate housing that requires drilling and screw assembly.
Solution Approach 2:
Positioning posts and socket holes serve as intermediary elements between the cover/base and the frame. These pre-designed positioning features facilitate easy alignment and secure attachment without requiring drilling operations or separate screw assemblies, thus simplifying the installation process while maintaining reliability.
2Stability of the object's composition
If positioning posts and socket holes with square structures are used to assemble the cover and bottom seat, then the components can be connected, but the assembly process becomes difficult
Solution Approach 1:
The patent employs asymmetric positioning features including L-shaped positioning blocks and corresponding positioning grooves. The L-shaped block has a vertical side and a horizontal side that fit into the positioning groove, creating a unique orientation that guides proper assembly while preventing incorrect installation. This asymmetric design simplifies the assembly process by providing intuitive alignment cues.
Solution Approach 2:
The patent utilizes rounded positioning posts that fit into corresponding recesses in the bottom seat. The curved surfaces of the positioning posts and recesses facilitate easy insertion and rotation during assembly, allowing the components to be connected smoothly without the difficulty of fitting square structures together. The rounded features also accommodate minor misalignments during the assembly process.
3Stability of the object's composition
If the stopper is arranged in the middle of the guiding groove, then the positioning pin can be retained, but tool access is required to disassemble the device
Solution Approach 1:
The patent extracts the stopper from the middle of the guiding groove and relocates it to the end of the groove. This repositioning allows the positioning pin to be easily removed by simply pulling it out from the end, eliminating the need for tools to reach into the groove and pluck the pin. The stopper at the end of the groove continues to retain the positioning pin during operation but does not hinder disassembly.
4Reliability
If multiple screw assemblies are used to fix the housing, then secure installation is achieved, but the number of parts and installation time increases
Solution Approach 1:
The patent merges the mounting functions into the cover and base assemblies themselves, which include integrated positioning posts and mounting features. By combining the housing structure with the mounting mechanisms, the device eliminates the need for multiple separate screw assemblies, reducing both the number of parts and the time required for installation while maintaining secure attachment to the frame.
