Solution Overview
Problem
The construction of elevator shaft support structures is laborious, time-consuming, and hampers aesthetics, while requiring skilled labor and portability is a concern.
Innovation Solution
A structure comprising a first column with 'L' shaped sections interconnected by a semicircular section, a second column for reinforcement, and beams with grooves for covering plates and right angled sections, allowing for modular assembly and reduced fasteners, using lightweight materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforced cement concrete wall or masonry wall is used as support structure, then structural strength and stability are improved, but construction time and labor requirements increase
Solution Approach 1:
The support structure is divided into multiple pre-fabricated modular components (vertical columns, horizontal beams, connection elements) that can be manufactured separately and assembled on-site. This segmentation enables parallel production of components while reducing on-site construction time and skilled labor requirements.
Solution Approach 2:
Structural components are pre-fabricated off-site with predetermined connections and reinforcements before delivery to the installation location. This preliminary action allows complex structural elements to be prepared in advance, significantly reducing on-site assembly time and labor intensity.
2Stability of the object's composition
If a reinforced cement concrete wall or masonry wall is used as support structure, then structural stability is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The structure is segmented into modular components that can be independently designed with aesthetic considerations. Each module can feature clean lines, uniform joints, and consistent finishes that contribute to overall aesthetic appeal while maintaining structural integrity through standardized connection details.
Solution Approach 2:
Different portions of the structure are designed with appropriate qualities - structural components provide strength and stability while surface finishes, joint designs, and material selections are optimized for aesthetic appearance in visible areas, creating a harmonious balance between form and function.
3Strength
If traditional support structure construction methods are used, then structural strength is improved, but portability deteriorates
Solution Approach 1:
The support structure is divided into discrete, transportable modular units with standardized dimensions and connection interfaces. This segmentation enables the structure to be disassembled, transported to different locations, and reassembled, providing portability while maintaining structural strength through engineered connections.
Solution Approach 2:
The structure transitions from a fixed, permanent installation to a dynamic, reconfigurable system. Modular components can be easily assembled and disassembled, allowing the structure to adapt to different locations and configurations while maintaining structural integrity through standardized connection mechanisms.

AI summary
A structure 10 for constructing an elevator shaft is provided. The structure includes a first column 20 to withstand stress. The first column is constructed by coupling a first groove 30 to ‘L’ shaped sections 40. The ‘L’ shaped sections are interconnected by a semicircular section 50 forming at least one slot 60 at a junction of coupling between the ‘L’ shaped sections and the semi-circular section. The structure includes a second column 70 to provide reinforcement to the first column. The structure includes a base plate 140 including projections to secure the second column to the base plate via fasteners. The structure includes beams including a corresponding third groove 170 and a corresponding fourth groove 180. The corresponding third groove and the corresponding fourth groove are to receive a corresponding covering plate 190 and a corresponding right angled section 200 respectively to mount a corresponding sheet 210.
