Adjustable Drive Rod for Bottom Seal Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking rods in doors and windows with drop-down bottom seals require the door or window to be removed for seal replacement, which is physically demanding and time-consuming, and can damage the floor surface during installation.
Innovation Solution
A length-adjustable drive rod system that allows the bottom seal to be replaced without removing the door or window, featuring a connecting rod with two predefined configurations and a fastening area that adjusts its overall length, enabling the rod to be shortened for seal removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the door or window is removed for bottom seal replacement, then the bottom seal can be replaced, but the process becomes physically demanding and time-consuming
Solution Approach 1:
The drive rod is divided into multiple sections (first drive rod section, second drive rod section) that can be detachably connected. This segmentation allows the second section to be separated from the first section to enable bottom seal replacement without removing the entire door or window assembly, making the replacement process easier and faster.
Solution Approach 2:
The drive rod transitions from a fixed structure to a dynamically adjustable structure. The fastening area allows the drive rod to change its overall length by detachably connecting or separating the sections, enabling easy access to the bottom seal for replacement without permanent structural changes to the door or window.
2Ease of manufacture
If the door or window is removed for bottom seal replacement, then the bottom seal can be replaced, but the process becomes complex and requires trained professionals
Solution Approach 1:
The drive rod is segmented into detachable sections with a simple fastening area mechanism. This segmentation reduces replacement complexity by allowing straightforward separation and reconnection of rod sections, eliminating the need for complex disassembly procedures and trained professionals.
Solution Approach 2:
The second drive rod section is extracted from the first section at the fastening area to provide access to the bottom seal. This extraction mechanism simplifies the replacement process by allowing the seal to be accessed and replaced without removing the entire door or window assembly.
3Reliability
If the drive rod extends through the bottom seal, then the locking function is maintained, but the bottom seal cannot be replaced without removing the door
Solution Approach 1:
The drive rod is segmented into detachable sections that can be separated at the fastening area. This allows the second section to be removed from the first section, providing access to the bottom seal for replacement while maintaining the locking function when the sections are connected.
Solution Approach 2:
The drive rod structure is made dynamic through the detachable connection at the fastening area. The rod can transition between a connected state (maintaining locking function) and a separated state (enabling bottom seal replacement), resolving the contradiction between reliability and ease of manufacture.
4Ease of manufacture
If the drive rod is made length-adjustable, then bottom seal replacement is enabled, but the structure becomes more complex
Solution Approach 1:
The drive rod is segmented into a finite number of sections (first and second sections) with a simple fastening area for detachable connection. This segmentation provides length adjustability for bottom seal replacement while keeping the structural complexity manageable through a limited number of components.
Solution Approach 2:
The fastening area is designed with specific local properties that enable detachable connection between drive rod sections. This localized feature provides the necessary length adjustment capability without requiring complexity throughout the entire drive rod structure.
