Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing room cell arrangements face challenges in assembling continuous facades without disrupting elements and achieving a clamping force comparable to external screws, while also allowing for easy assembly and disassembly of vertical connecting means.
Innovation Solution
The use of internal wedge-clamping vertical connecting means that can be manually attached and detached, allowing for a stable and secure internal clamping connection without external disruptions, enabling the attachment of facades and achieving a clamping force equal to or greater than external screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external clamping screws are used to connect vertical corner pieces, then the assembly is simple and easy to install, but the facade cannot be routed over the corner connectors and external appearance is disrupted
Solution Approach 1:
The clamping function is extracted from external screws and moved inside the corner connector hollow bodies. The internal clamping elements (clamping plates, clamping arms, or wedge-shaped elements) are contained within the corner connectors, eliminating external visible components while maintaining the clamping function.
Solution Approach 2:
The clamping mechanism is nested within the corner connector hollow bodies. The internal clamping elements are housed inside the corner connectors, with the clamping action occurring internally between the upper and lower corner pieces without requiring external attachment points.
2Object-generated harmful factors
If internal wedge-clamping vertical connecting means are used, then facade attachment is enabled without external disruptions, but assembly and disassembly require manual intervention
Solution Approach 1:
The corner connectors are pre-assembled with the internal clamping mechanism in a ready-to-connect state. The upper corner piece can be positioned on the lower corner piece with the clamping elements already in place, requiring only manual insertion or positioning rather than complex assembly steps.
3Force
If external clamping screws are used, then high clamping force can be achieved, but the clamping force is not sufficient when compared to internal wedge clamping
Solution Approach 1:
The clamping mechanism transitions from a screw-based system to a wedge-based system, changing the mechanical parameter from rotational force to inclined plane force multiplication. The wedge-shaped elements convert horizontal insertion force into vertical clamping force through the wedge angle, achieving high clamping force with simpler linear motion.

Function Achieved in This Case
Facades can be attached without external disruptions, and the connections can be easily assembled and disassembled, providing a stable and secure internal vertical connection that maintains the structural integrity and aesthetic appeal of the room cells.
Implementation Method 1
comprising a wedge-shaped element which, in a clamping position, secures the upper corner piece (20.1) of the lower space cell (11.1) in a releasable, vertical clamping against each other with the lower corner piece (20.2) of the upper space cell (11.2)
Implementation Method 2
The two wedge surfaces (101.1, 101.2) of the wedge-shaped element (29) enclose a wedge angle (102)
