Solution Overview
Problem
Existing construction methods lack a versatile and adjustable structural header beam solution for reinforcing or replacing decayed or broken header beams, particularly in building structures, while also accommodating the integration of functional elements like drains and pipes.
Innovation Solution
A multi-element header beam made of conventional structural materials, featuring a center section with longitudinal slots and end sections with holes, allowing for adjustable length through bolted assembly, providing structural integrity and accommodating various load-bearing configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fixed-length header beam is used, then structural integrity is maintained, but adaptability to different structural configurations and load-bearing requirements is limited
Solution Approach 1:
The header beam is divided into multiple segmentable components including end sections with holes and center sections with longitudinal slots. These segments can be assembled in different configurations using bolts and washers, allowing the header beam to adapt to various structural requirements while maintaining structural integrity through standardized connection elements.
Solution Approach 2:
The header beam incorporates adjustable length capability through the interaction between end section holes and center section slots. The longitudinal slots allow for dynamic adjustment of the header beam length by positioning end sections at different locations along the center section, enabling adaptation to different structural configurations.
2Adaptability or versatility
If the header beam length is made adjustable, then versatility in accommodating different structural configurations is improved, but the complexity of assembly and adjustment increases
Solution Approach 1:
The header beam is divided into modular segments with standardized connection interfaces. End sections with pre-drilled holes and center sections with longitudinal slots create a systematic assembly pattern that simplifies the adjustment process, as workers only need to position segments and secure them with bolts and washers rather than performing complex fabrication or fitting operations.
Solution Approach 2:
The header beam length can be adjusted by changing the positional parameter of end sections relative to center sections. The longitudinal slots provide a range of acceptable positions, allowing for simple length adjustment without requiring complex calculations or specialized tools, thereby maintaining ease of operation while achieving adjustability.
3Strength
If multiple bolts are used to connect end sections to center sections, then structural integrity and load-bearing capacity are improved, but the complexity of assembly and material requirements increase
Solution Approach 1:
The connection system is segmented into standardized components: end sections with holes, center sections with slots, bolts, and washers. This segmentation allows for systematic application of multiple bolts in consistent patterns, ensuring adequate load-bearing capacity while simplifying assembly procedures and material procurement through standardization.
Solution Approach 2:
The number and positioning of bolts are optimized for specific local requirements. Multiple bolts are used at critical connection points where vertical loads are transmitted, while the exact number can be adjusted based on the specific load-bearing requirements of different structural configurations, providing localized strength where needed without unnecessary complexity elsewhere.

AI summary
A longitudinal length adjustable header made up of a center section and two end sections moveably attached to the center section. The center section has an “L” shaped cross section and at least two longitudinal slots that are adapted to receive bolt means there through. The end sections have a plurality of apertures that align with the slots in the center section and are adapted to receive bolt means there through. The end sections are longitudinally slidable with respect to the center section whereby enabling adjusting the length of the header.
