Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If loose timber house method is used, then building flexibility is improved, but construction time increases and exposure to weather damage increases
Solution Approach 1:
The wall elements are pre-assembled with insulation and cladding in a controlled factory environment before delivery to the construction site. This preliminary preparation of building components eliminates time-consuming on-site assembly operations and protects materials from weather exposure during construction.
Solution Approach 2:
The building is divided into standardized wall elements that can be independently manufactured and assembled. This segmentation allows for parallel production of multiple wall sections while maintaining design flexibility through modular configuration.
2Productivity
If prefabricated elements are used, then construction speed is improved, but equipment cost and transportation cost increase
Solution Approach 1:
The wall elements are designed with optimized dimensions and weights that can be handled by manual labor or simple lifting equipment. By adjusting the size and mass parameters of the prefabricated components, the patent eliminates the need for expensive heavy-lifting cranes while maintaining fast assembly speeds.
3Productivity
If prefabricated elements are used, then construction speed is improved, but transportation cost increases
Solution Approach 1:
The building is divided into modular wall elements of optimized size that maximize transport efficiency while minimizing individual component weight. This segmentation allows standard transportation vehicles to carry multiple elements, reducing the number of trips and overall transportation cost compared to moving fewer, larger components.
4Ease of operation
If angled edges are used in wall elements, then assembly ease is improved, but manufacturing precision requirements increase
Solution Approach 1:
The angled edges are implemented only at specific locations where they provide assembly guidance, while other portions of the wall elements maintain standard rectangular geometry. This localized application of asymmetry simplifies the overall manufacturing process while still providing the self-aligning benefit during assembly.

AI summary
The present invention relates to a wall element (10) comprising an upper (21 ) and a lower (22) edge element, and two side elements (/25, 26) between the upper and lower elements. A rectangular board (27) is covering the elements. The edges (23, 24) of the upper and lower elements are arranged at an angle a with respect to a plane P perpendicular to an outer surface of the panel. The angle a lies within the interval 20° to 45°. The invention further relates to a wall section comprising at least two wall elements and a method for building the wall section.
