Tool-Free Sliding Door Leaf Attachment for Easy Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insect screen sliding doors are difficult to install and detach due to the need for tools and multiple people to attach the door leaf to guide rails, and disassembly requires careful handling to avoid damaging remaining guide rails.
Innovation Solution
The door leaf is attached or detached from guide elements using connecting elements with protruding and recessed designs, allowing for a positive and/or non-positive, detachable connection, or through magnetic attachment, eliminating the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door leaf is attached to guide rails using screws, then the connection is secure and reliable, but the installation requires multiple people and tools, and disassembly risks damaging remaining guide rails
Solution Approach 1:
The connection system is segmented into separate components: a connection element with threadable portion and a receiving element with threaded bore. This allows the door leaf to be attached to guide rails through individual connection elements rather than requiring multiple people to hold the entire door leaf against the track, simplifying installation while maintaining secure connection.
Solution Approach 2:
The connection element includes a threadable portion that can be manually screwed into the threaded bore of the receiving element without requiring additional tools or assistance. The self-tapping or threading mechanism allows single-person installation and disassembly, eliminating the need for multiple people while maintaining reliable connection through threaded engagement.
2Reliability
If conventional screw attachment is used, then secure connection is achieved, but installation time increases and requires multiple people
Solution Approach 1:
The connection element and receiving element are pre-designed with matching threading features during manufacturing. This preliminary preparation of threaded interfaces eliminates the need for on-site threading operations or complex alignment procedures, allowing rapid attachment by simply screwing the connection element into the receiving element, significantly reducing installation time while ensuring secure connection.
3Adaptability or versatility
If the door leaf is detached from one guide rail, then repositioning is possible, but significant force is exerted on remaining guide rails causing potential damage
Solution Approach 1:
The attachment system is segmented into independent connection elements at different locations along the door leaf. Each connection element can be independently detached from its corresponding guide rail without affecting the structural integrity or experiencing significant force transmission to other guide rails, enabling safe repositioning while protecting guide rail integrity.
