Floor Threshold Transverse Support for Drainage and Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ground sills for sliding doors and windows are not suitable for easy drainage and are difficult to manufacture, as they often require separate attachment of webs and do not allow for adjustable load distribution.
Innovation Solution
A ground sill design featuring transversely aligned insertion support parts between the base and cover profiles, which are connected before insertion into the base profile, facilitating easy manufacturing and adjustable load distribution by varying the distance between support parts, and incorporating spacers for uniform load transfer and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If webs are aligned in the longitudinal direction to absorb load, then load-bearing capacity is improved, but drainage capability deteriorates
Solution Approach 1:
The threshold is divided into a base profile and a cover profile that can be manufactured separately and assembled together. The insertion support parts are separate components that can be inserted into the base profile, allowing the cover profile to be designed with drainage openings without compromising load-bearing structure.
Solution Approach 2:
The insertion support parts are oriented transversely (perpendicularly) to the longitudinal direction of the threshold, creating a new dimensional arrangement for load support. This transverse orientation allows water to flow longitudinally along the threshold surface without being blocked by support structures, thus enabling drainage while maintaining load-bearing capacity.
2Stability of the object's composition
If separate attachment of webs is required, then structural integrity is improved, but manufacturing complexity increases
Solution Approach 1:
The base profile and cover profile are designed to be assembled together through the insertion support parts, forming an integrated threshold structure. The insertion support parts serve multiple functions: they support the cover profile, provide drainage pathways, and can be connected to each other to form continuous support structures along the threshold length.
Solution Approach 2:
The insertion support parts perform multiple functions simultaneously: they provide structural support for the cover profile, create drainage channels when arranged transversely, and can be connected to form continuous support systems. This multi-functionality reduces the need for separate components and simplifies manufacturing.
3Ease of manufacture
If fixed number of support parts is used, then manufacturing simplicity is improved, but adaptability to different loads deteriorates
Solution Approach 1:
The threshold design allows for dynamic adjustment of the number and spacing of insertion support parts based on the specific application requirements. Different numbers of support parts can be used depending on the length of the threshold and the expected load, providing adaptability while maintaining simple manufacturing processes.
Solution Approach 2:
The spacing between insertion support parts can be varied to adapt to different load conditions and threshold lengths. This parameter adjustment allows the same basic component design to be used across different applications, maintaining manufacturing simplicity while achieving adaptability to various structural requirements.
