Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual positioning of primary frames is used, then installation flexibility is maintained, but positioning precision and alignment accuracy deteriorate
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated motorized moving system that provides six degrees of freedom. Motors and drive mechanisms substitute for manual operations, enabling precise positioning without human intervention while maintaining the ability to adjust and reposition primary frames.
Solution Approach 2:
The system incorporates self-positioning capabilities through automated moving mechanisms that can independently adjust the location and orientation of primary frames. The built-in motors and control systems enable the structure to self-align and self-position without requiring external manual intervention.
2Productivity
If individual primary frames are positioned separately, then installation simplicity is maintained, but installation time and coordination efficiency deteriorate
Solution Approach 1:
The patent implements a universal control system that can manage multiple primary frames simultaneously through a centralized interface. This multi-functional control architecture enables coordinated positioning of numerous frames using the same control mechanisms, significantly improving installation efficiency while maintaining manageable system complexity.
Solution Approach 2:
The control systems of individual primary frames are merged into a single centralized control unit. This consolidation allows simultaneous coordination of multiple frames, enabling batch positioning operations that dramatically reduce installation time compared to individual separate positioning operations.
3Manufacturing precision
If angular position adjustment is manual, then mechanical simplicity is maintained, but positioning precision and alignment capability deteriorate
Solution Approach 1:
Manual angular adjustment mechanisms are replaced with motorized drive systems that provide precise rotational control. The motorized systems substitute for manual cranking or adjusting, delivering superior angular positioning precision while the centralized control interface keeps operational complexity manageable through automation.
4Ease of repair
If covering elements are installed before device installation, then aesthetic appearance is maintained, but accessibility and maintenance difficulty increase
Solution Approach 1:
The wall structure is segmented into modular primary frames that can be independently positioned and adjusted. This segmentation allows devices to be installed on the frames before final aesthetic covering elements are applied, as the modular frames provide both structural support and mounting surfaces during the installation process.
Solution Approach 2:
The system incorporates dynamic positioning capabilities that allow the primary frames to be adjusted and repositioned even after initial installation. This dynamic adjustability enables fine-tuning of device positions and orientations to achieve optimal aesthetic appearance while maintaining easy accessibility for maintenance and repairs.

AI summary
The modular wall structure comprises multiple primary frames (10) for carrying cladding elements (11) and building service devices (12); a secondary frame (20) for supporting the primary frames (10); and a moving system for moving each primary frame (10) with respect to the secondary frame (20) in six degrees of freedom. The moving system comprises at least three moving units (40) for each primary frame (10). Each moving unit (40) comprises a housing (50) attached to the primary frame (10); a spherical joint bushing (61) inside the housing (50), wherein said joint bushing (61) can be translated parallel to the plane of the primary frame (10); a first drive unit (72) attached to the primary frame (10) for moving the ball joint bushing relative to the housing (50) along a first direction (x) by means of a first shaft (70); a second drive unit (82) attached to the primary frame (10) for moving the ball joint bushing relative to the housing (50) along a second direction (y) perpendicular to the first direction (x) through a second axis (80); and a third drive unit (92) attached to the secondary frame (20) for moving the ball joint bushing relative to the secondary frame (20) in a third direction (z) perpendicular to both the first direction (x) and the second direction (y), through a third shaft. A free end of the first shaft (70) is slidably mounted into a first guide groove of the ball joint bushing, said first guide groove (62) extending in the second direction (y). A free end of the second shaft is slidably mounted in a second guide groove of the ball joint bushing, said second guide groove extending in the first direction (x). A free end of the third shaft is mounted into a ball joint rotatably arranged in said ball joint bushing.
