Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for positioning building elements, such as CLT or GLT panels, are labor-intensive, prone to geometric errors, and require manual correction, with a high risk of human error and stringent manufacturing quality requirements.
Innovation Solution
A method utilizing elastic properties of materials and gravity to position building elements by placing leading and corresponding positioning parts on the element and foundation, ensuring the inequality E1×E2 < (τ×A×L×(E1×S1+E2×S2)/(Δ×S1×S2) is satisfied, allowing self-leveling and accurate positioning without manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual positioning methods are used with cranes and hand tools, then building elements can be placed and adjusted, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The positioning elements are designed to automatically self-level and self-position the building element through elastic deformation when the element is lowered onto the foundation, eliminating the need for manual adjustment with hand tools and reducing labor requirements
Solution Approach 2:
The manual mechanical adjustment system is replaced with an elastic-mechanical self-positioning system where positioning elements made of elastic material automatically adjust the building element's position through elastic deformation when loaded, substituting human-operated hand tools with an automatic mechanical-elastic system
2Manufacturing precision
If manual positioning and adjustment is performed, then building elements can be located, but geometric errors accumulate and require correction
Solution Approach 1:
The positioning elements automatically compensate for geometric errors and misalignments through elastic deformation, self-correcting the position of the building element without requiring manual measurement and correction, thereby reducing error accumulation
Solution Approach 2:
The positioning elements utilize elastic deformation (change in physical state) to absorb and compensate for position deviations, allowing the system to adapt to geometric variations and maintain high positioning accuracy despite initial misalignments
3Ease of manufacture
If traditional positioning methods are used, then building elements can be installed, but the process is complex and requires multiple steps
Solution Approach 1:
The complex manual positioning and adjustment steps are extracted and replaced by a single integrated self-positioning mechanism where positioning elements embedded in the foundation automatically guide and level the building element during lowering, simplifying the installation process to essentially one operation
Solution Approach 2:
The functions of positioning, leveling, and alignment are merged into a single self-positioning system where the positioning elements perform multiple functions simultaneously through elastic deformation, eliminating the need for separate manual operations

AI summary
The invention relates to the field of construction, in particular to the assembly of buildings or structures from prefabricated modular building elements, for example wooden panels.A method for positioning building elements, comprising the following steps: lifting a building element; moving the building element in a suspended state to a position as close as possible to the design position; lowering the building element onto a foundation; wherein the elastic deformation of the building element and the foundation is within a specified range; wherein leading positioning elements are arranged on the lower part of the building element; wherein corresponding positioning elements are installed into the upper surface of the foundation; and wherein the building element is lowered onto the foundation until its positioning elements come into contact with the foundation's positioning elements, after which the building element is allowed to bear its own weight again.
