Disappearing Door Counterframe Anchorage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current counterframes for disappearing sliding doors lack the ability to securely anchor sanitary equipment, electrical sockets, and hanging furniture due to their structural composition, which prevents effective fixation of plugs and other objects.
Innovation Solution
A counterframe design featuring a rigid shell with a layered structure of semi-soft and rigid materials, allowing for the support of hanging objects and the passage of pipes and cables, with cross beams that enable anchorage of finishing elements and plugs at any point, overcoming previous architectural limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional counterframe structure made of zinc-coated steel plates with ribbings is used, then the counterframe provides structural support and wall integration, but it cannot securely anchor sanitary equipment, electrical sockets, or hanging furniture due to lack of plug fixation capability
Solution Approach 1:
The counterframe is divided into multiple functional layers: a first layer of semi-soft material for deformation and plug anchorage, and a second layer of rigid material for structural support. This segmentation allows each layer to perform its specific function independently, enabling plug fixation without compromising overall structural integrity.
Solution Approach 2:
The invention uses a composite structure combining semi-soft material (first layer) and rigid material (second layer). The semi-soft material deforms to accommodate plugs and provide anchorage, while the rigid material maintains structural strength. This composite approach solves the contradiction by integrating both flexibility for anchorage and rigidity for support within a single counterframe system.
2Shape
If the counterframe uses a thin rigid structure to maintain wall planarity, then aesthetic integration is improved, but the ability to support hanging objects and facilitate plug fixation is compromised
Solution Approach 1:
The solution moves from a two-dimensional thin rigid plate to a three-dimensional layered structure. The first layer of semi-soft material provides deformation capability in one dimension, while the second layer of rigid material provides structural strength in another dimension. This dimensional transition allows the counterframe to maintain wall planarity while supporting hanging objects through the layered composite structure.
3Ease of operation
If conventional fixing techniques are used on the counterframe, then installation simplicity is maintained, but the counterframe cannot support sanitary equipment, electrical sockets, or hanging furniture
Solution Approach 1:
The semi-soft material in the first layer automatically deforms and adapts to the shape of plugs and anchorage points during installation. This self-deformation capability eliminates the need for complex pre-prepared holes or specialized fixing mechanisms, allowing conventional fixing techniques to work effectively while maintaining ease of installation.
