Sliding Door Post Partition Accessory for Watertight Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming partition walls in sliding door or window posts are inefficient due to poor expansion of sealing foams, leading to leaks and the need for multiple injections, which are time-consuming and require excessive foam, especially in larger cavities.
Innovation Solution
An accessory with an open structure, axially shiftable and lockable within the post, that matches the cavity's cross-section, allowing for precise positioning and minimal sealing agent distribution, using a resilient element to secure the accessory and facilitate a watertight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foam is injected into the hollow post to form a partition wall, then the post can be sealed to form drainage channels, but the foam may not expand well and cavities may be formed in the sealing causing water leaks
Solution Approach 1:
A support element is introduced as an intermediary object inside the hollow post before foam injection. This support element provides a physical framework that guides foam expansion and prevents cavity formation, ensuring reliable watertight sealing without compromising manufacturing quality
Solution Approach 2:
The support element is inserted into the hollow post before the foam injection process. This preliminary action prepares the cavity structure to receive foam uniformly, preventing expansion defects and ensuring high sealing quality from the start
2Volume of stationary object
If foam is injected into a post with large cavity dimensions, then the cavity can be sealed, but the foam distributes sidelong without forming a proper partition requiring successive injections that consume more time and foam
Solution Approach 1:
The support element acts as a mediator that channels foam flow vertically through the large cavity, preventing sidelong distribution. This allows complete cavity coverage in a single injection, dramatically improving productivity by eliminating successive injection steps
Solution Approach 2:
The support element creates localized pathways within the large cavity that direct foam to specific areas. This ensures uniform vertical distribution and proper partition formation throughout the entire cavity volume without waste
3Reliability
If foam is injected in successive steps to obtain a tight partition wall, then watertight sealing can be achieved, but much time is required and much foam is required
Solution Approach 1:
The support element serves as a permanent intermediary framework that ensures single-step foam injection produces a tight partition wall. This eliminates the need for successive injections, reducing sealing time while maintaining partition tightness
Solution Approach 2:
By pre-installing the support element, the system prepares the cavity to receive foam in a single injection that will naturally form a tight partition. This preliminary preparation eliminates time-consuming multiple injection cycles
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures quick and effective watertight sealing between compartments with minimal sealing agent, reducing time and cost, while allowing easy manufacturing and precise positioning of the partition wall.
Implementation Method 1
The above-mentioned means to lock the accessory are formed of a resilient element which can clasp in an opening provided to that end in the post
Implementation Method 2
a sealing agent which is injected round the accessory so as to realise a partition between compartments on either side of the opening

AI summary
Accessory to form a partition wall in the post of a sliding door or a sliding window so as to separate compartments in the cavity of the post, characterised in that the accessory can be axially shifted in the post and has a shape which practically corresponds to the shape of the cavity's cross section, and in that said accessory is provided with means to automatically lock the accessory, when it is shifted, at an opening provided in the post on the spot where the partition wall is to be provided.
