Rotatable Spool Assembly for Manual Tape Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The removal of temporary marking tapes from paved surfaces is a slow and labor-intensive process, often placing workers in hazardous situations and causing damage to the surfaces, with existing methods being inefficient and physically demanding.
Innovation Solution
A non-ridable, non-motorized temporary tape removal machine with a chassis, vertical support post, horizontal arm, and rotatable spool assembly that allows the spool to be positioned on either side of the chassis, enabling efficient winding and removal of tape, and can be self-propelled or pushed by hand or auxiliary devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual removal methods are used, then workers can remove temporary marking tapes, but the process is slow and labor-intensive requiring significant physical effort
Solution Approach 1:
The removal machine is designed to be self-propelled with an engine that drives both the wheels and the spool assembly, eliminating the need for manual pushing or towing while the operator simply guides the machine. The spool automatically winds the tape as the machine moves forward, making the removal process self-service rather than labor-intensive.
Solution Approach 2:
The patent replaces manual mechanical removal with an engine-powered system. The engine provides mechanical power to drive the spool assembly through a transmission system, substituting human physical effort with motorized power. This allows continuous operation without the fatigue and speed limitations of manual labor.
2Reliability
If traditional manual removal methods are used, then workers can remove temporary marking tapes, but workers are placed in hazardous situations
Solution Approach 1:
The machine performs the physically demanding work of pulling and winding the tape automatically through its engine-powered spool system. The operator only needs to guide the machine, eliminating exposure to hazardous situations involving heavy physical manipulation of the tape and reducing physical strain significantly.
3Adaptability or versatility
If the spool assembly is fixed on one side of the chassis, then the structure is simpler, but the machine cannot operate efficiently in tight spaces or access areas on both sides
Solution Approach 1:
The horizontal arm is made rotatable relative to the vertical support post, allowing the spool assembly to dynamically reposition between left and right sides of the chassis. This dynamic configuration enables the machine to adapt to different work scenarios, including tight spaces and areas requiring bilateral access, while the rotation mechanism adds only moderate complexity to the overall structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine significantly reduces labor and time required for tape removal, enhances safety by minimizing physical strain, and allows for efficient operation in tight spaces without causing damage to the surfaces.
Implementation Method 1
The spool assembly includes a spool, and the spool has friction engagement with the temporary tape to wind the tape onto the spool

AI summary
Non-ridable and non-motorized machines for removing temporary tape that include a chassis or frame having front and rear wheels, a vertical support post mounted on the frame or chassis between the front and rear wheels, a horizontal arm mounted on the vertical support post, and a rotatable spool assembly attached to one end of the horizontal arm for winding used temporary tape thereon, wherein the horizontal arm is rotatably coupled to the vertical support to allow the spool assembly to be positioned on either side of the chassis when the horizontal arm is rotated with respect to the vertical support post. The non-ridable temporary tape removal machine can be manually and guided along a pavement during a tape removal operation. The non-motorized temporary tape removal machines can be or coupled to an auxiliary motorized device that pushes the non-motorized temporary tape removal machine during a tape removal operation.
