Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for bending vinyl tile boards to create seamless transitions on stairways are either not portable, lack a comprehensive heating mechanism, or fail to provide a seamless interface with flooring, leading to potential tripping hazards and aesthetic issues.
Innovation Solution
A portable bending machine with a heating oven beneath a frame base, featuring a cylindrical bar and lever-operated forming mechanism, allows for adjustable contouring of vinyl tile board ends to create a seamless arcuate shape that can be easily transported and installed on stair steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a stationary bending system with multiple burners is used, then bending capability is achieved, but portability and ease of transport are lost
Solution Approach 1:
The bending system is divided into separate functional modules: a heating module with burners, a forming module with contoured surface, and a support module. This segmentation allows each module to be independently optimized and easily transported to different installation sites while maintaining complete bending functionality when assembled.
Solution Approach 2:
The system incorporates adjustable and movable components including adjustable burners that can be positioned at different locations, an adjustable stop bar with movable positioning, and a pivotally movable table. These dynamic features enable the system to adapt to various board sizes and bending requirements while maintaining portability through compact configuration.
2Ease of operation
If vinyl tile board ends are not arcuately contoured, then installation is simpler, but tripping hazards and aesthetic issues occur
Solution Approach 1:
The system employs a table with a contoured surface that provides a curved forming surface for the vinyl tile board ends. This curvature creates an arcuate contour that eliminates sharp edges and creates a seamless transition between the vinyl flooring and stair steps, thereby eliminating tripping hazards while improving aesthetics.
Solution Approach 2:
The arcuate contouring is performed as a preliminary step before final installation. The board end is heated and formed into the desired curved shape in advance, allowing it to be seamlessly fitted to the stair step configuration before the final adhesive bonding and installation steps.
3Ease of manufacture
If heating temperature is increased to achieve pliability, then forming capability improves, but risk of material degradation increases
Solution Approach 1:
The system controls the heating process by adjusting burner parameters including flame size, burner position, and heating duration. The adjustable burners can be positioned at different locations and configured to provide controlled thermal energy, heating the vinyl tile board to the precise temperature needed for pliability while avoiding excessive heat that would cause material degradation.
Solution Approach 2:
The system applies heating locally to only the portion of the vinyl tile board that needs to be formed, rather than heating the entire board. This partial action approach achieves the necessary pliability in the specific forming zone while minimizing overall thermal exposure and reducing the risk of material degradation in non-forming areas.

Implementation Method 1
a heating assembly mounted within said frame below the frame base member to heat an end section of a board member to a temperature within a predetermined temperature range which forms the end section into a pliable state
Implementation Method 2
heating the end section to the predetermined temperature within the predetermined temperature range to form the pliable end section of the board member
Implementation Method 3
arcuately forming the end section of the board member around the cylindrical bar when the end section of the board member is heated to the predetermined temperature within the predetermined temperature range forming the pliable end section of the board member

AI summary
A transportable/portable bending machine for arcuately contacting an end section of a synthetic resin or plastic composition planar member which includes a frame having a substantially planar frame base member. The machine includes a heating assembly mounted within the frame below the planar frame base member to heat an end section of the synthetic resin or plastic composition to a temperature which allows the end section to become pliable. A forming mechanism includes a cylindrical bar and a rotatable forming member for arcuately forming the end section of the resin or plastic composition planar member around the cylinder bar. An adjustment height mechanism adjusts the displacement distance between an upper surface of the planar frame base member and the cylindrical bar with an adjustable and rotatable lever mechanism connected to the forming mechanism for arcuately displacing the forming mechanism through a predetermined arc length.
