Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand scraping hardwood floors to create a distressed visible pattern is time-consuming and costly, as each floor must be individually hand-sculpted, lacking an efficient method for mass production while maintaining authenticity.
Innovation Solution
An abrading device comprising two rotationally driven contact rolls with patterned sleeves and an abrading belt, where the rolls are oscillated in linear reciprocating motions to create a distressed pattern on the floor surface, allowing for simultaneous and efficient abrading of multiple floors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hand scraping is used to create distressed pattern on floor, then authentic distressed appearance is achieved, but production time and cost increase significantly
Solution Approach 1:
The patent uses a mold with patterned cavities that replicates the distressed floor pattern automatically. The mold contains multiple recesses shaped like footprints or distress marks, which are copied onto the floor surface through the abrading process, eliminating the need for manual scraping while maintaining authentic appearance
Solution Approach 2:
The invention changes the parameters of the abrading process by using oscillating motion combined with rotational motion of the contact roll. The oscillation creates varying pressure and contact patterns that replicate hand-scrapped effects, while the rotation enables continuous processing of multiple floors simultaneously
2Manufacturing precision
If hand sculpting each floor individually is performed, then authentic distressed pattern is created, but labor cost and time consumption increase
Solution Approach 1:
The mold is segmented into multiple cavities representing different distress patterns or footprints. The contact roll is divided into multiple contact points that correspond to these cavities, allowing simultaneous creation of multiple distress patterns across different floors in parallel
Solution Approach 2:
The invention introduces dynamic oscillation motion to the contact roll, causing it to vibrate back and forth during rotation. This dynamic motion creates variable pressure and contact patterns that simulate hand-scrapped effects, while enabling continuous automated processing that reduces overall time
3Productivity
If automated abrading device is used to increase productivity, then processing speed improves, but ability to maintain authentic distressed appearance deteriorates
Solution Approach 1:
The contact roll is equipped with an oscillation mechanism that causes it to vibrate in a linear reciprocating motion while rotating. This mechanical vibration creates dynamic contact patterns with the floor surface that replicate hand-scrapped distress marks, maintaining authentic appearance while enabling automated continuous processing
Solution Approach 2:
The oscillation assembly creates periodic reciprocating motion that cycles back and forth during the abrading process. This periodic action produces repeated contact patterns that build up the distressed appearance, while the continuous rotation allows multiple floors to be processed simultaneously

AI summary
An abrading device for abrading a floor structure comprises a first abrading assembly and a second abrading assembly. The first and second abrading assemblies each have a rotationally driven contact roll provided with a sleeve having a plurality of cutouts formed in a pattern thereon. An abrading belt is trained over the sleeve. A first oscillation assembly is connected to the first abrading assembly and oscillates the contact roll of the first abrading assembly in a first direction via a linear reciprocating motion. A second oscillation assembly is connected to the second abrading assembly and oscillates the contact roll of the second abrading assembly in a second direction via a linear reciprocating motion. The first and second abrading assemblies consecutively abrade a top surface of the floor structure with the pattern formed by the cutouts on the respective sleeves to form a distressed visible pattern thereon.
