Floor Channel System with Adjustable Carrier Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor duct systems lack flexibility in design and installation, requiring multiple accessories for routing around corners and providing inadequate access for device installation, especially with modern office architecture that often features glass fronts and varied floor coverings.
Innovation Solution
A floor duct system with a U-shaped duct base, height-adjustable cover retaining profiles, and a detachable system carrier strip that can be positioned flexibly, along with a height-adjustable outlet brush and display means, allowing for adaptable cable routing and device installation, including corner routing with a single flat angle for both inside and outside corners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional floor duct system with fixed C-rail and non-adjustable components is used, then the structure is simple and easy to manufacture, but the system lacks flexibility for different installation situations and device mounting positions
Solution Approach 1:
The system employs a moveable system carrier strip that can be positioned at different locations along the duct base and fixed in various positions, transforming a static structure into a dynamic, adaptable system. The carrier strip can be moved horizontally and vertically to accommodate different device mounting requirements while maintaining structural integrity through engagement with the duct base.
Solution Approach 2:
The system carrier strip serves multiple functions: it acts as a mounting surface for electrical devices, provides structural support, enables cable management, and allows for adjustable positioning. This multi-functional component replaces the need for multiple specialized accessories, including corner pieces and fixed mounting rails, thereby providing versatility without proportionally increasing complexity.
2Adaptability or versatility
If multiple separate accessories like different flat angles are required for routing around corners, then the duct can be routed around corners, but the installer must carry several accessories and installation becomes more complex
Solution Approach 1:
The system carrier strip is designed to be universally applicable for both straight runs and corner routing. By positioning the carrier strip at different angles and locations within the duct, the same component accomplishes what previously required multiple specialized corner accessories, simplifying the installer's workload while maintaining corner routing capability.
Solution Approach 2:
The moveable carrier strip allows dynamic repositioning to create various routing configurations including corners, bends, and straight runs. This dynamic positioning capability eliminates the need for pre-determined fixed corner pieces, enabling the installer to adapt the same component to different routing requirements during installation.
3Ease of operation
If the duct system uses fixed mounting positions, then the structure is simple, but access for device installation is inadequate and flexibility is limited
Solution Approach 1:
The system carrier strip provides dynamic access to the duct interior by being movable along the duct length and adjustable in position. This allows installers to easily access cable routes and device mounting locations at any point along the duct, rather than being constrained to fixed access points, while the strip itself remains a relatively simple component.

AI summary
A U-shaped channel portion (1) has side walls (27), a bottom portion (28) and side cover retaining profiles (11). A removable lid (6) is provided for partially or fully covering the U-shaped channel portion for accommodating cover retaining profiles. A carrier strip (7) is detachably attached to the bottom of channel portion, for attaching electrical installation equipment. A covering strip (10) is provided as a floor covering at side walls of the channel portion. The height of the covering strip between cover retaining profile and side wall is adjusted.
