Modular Carpet Edge Beveling for Trip-Safe Floor Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high traffic areas like trade show exhibits, the transition between a base floor and carpeted areas often creates a tripping hazard due to elevated edges, and existing solutions like tape can be messy and hazardous if not applied properly.
Innovation Solution
A carpet with an elastomeric foam substrate featuring a beveled edge and an interlocking tab-and-notch structure for easy assembly, where the beveled edge is formed on-site by cutting a V-notch and folding the substrate to create a smooth transition between the base floor and the carpet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If carpet is laid directly on base floor, then carpet installation is simple, but elevated edges create tripping hazards
Solution Approach 1:
The carpet substrate is provided with a beveled edge at specific locations where transition to base floor is needed. This local modification creates a gradual slope rather than a sharp edge, eliminating tripping hazards while maintaining simple installation elsewhere.
Solution Approach 2:
The carpet substrate is divided into modular tiles with interlocking tab-and-notch structures. This segmentation allows flexible arrangement to create beveled edges at perimeter tiles while keeping interior tiles simple, balancing installation ease with safety.
2Object-affected harmful factors
If tape is used to bridge elevated edges, then transition is achieved, but tape becomes messy and hazardous if not applied properly
Solution Approach 1:
The harmful tape material is completely removed from the solution. Instead, the beveled edge structure itself creates the transition, eliminating the reliability issues associated with tape application and failure.
3Ease of operation
If carpet tiles are used for easy assembly, then installation is simplified, but determining which edges need bevels becomes complex
Solution Approach 1:
The carpet tiles are designed with asymmetric features including tabs on some edges and notches on corresponding edges. This asymmetry provides visual and physical guidance for proper orientation and placement, automatically indicating which edges should be positioned at perimeter locations requiring bevels.
4Object-affected harmful factors
If beveled edges are pre-formed on carpet substrates, then transition safety is improved, but adaptability to different exhibit configurations is reduced
Solution Approach 1:
The carpet system uses modular tiles that can be dynamically reconfigured for different exhibit layouts. Beveled edges are created by positioning specific tiles with appropriate orientations rather than having fixed pre-formed bevels, allowing adaptation to various configurations while maintaining safety.

AI summary
A carpet in the form of a substrate formed with a beveled leading edge and including means to form the beveled edge at the point of use and to securely lock adjacent pieces together along an adjacent side edge in a manner which permits the accommodation of different sized and configured areas and assembling and disassembling of the carpet pad to be readily accomplished.
