Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for creating openings in plastic covers over planting regions are labor-intensive, hazardous due to gas torch use, and cause arm fatigue, with inefficient and unhealthy emissions.
Innovation Solution
A tractor-pulled or self-propelled apparatus with a framework, burner elements, and a control system that automatically creates evenly spaced holes in plastic sheeting, reducing manual labor and emissions by using a power source and actuators to precisely control the burning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a gas torch is used to burn openings through the plastic cover, then openings are created in the plastic covering, but unhealthy effluent and fumes are emitted causing health risks
Solution Approach 1:
The patent replaces the gas torch (thermal/mechanical system) with a mechanical punching apparatus that uses a wheel with spikes to physically puncture the plastic covering. This substitution eliminates the combustion process entirely, removing the source of unhealthy effluent and fumes while maintaining the capability to create openings in the plastic covering.
Solution Approach 2:
The patent converts the harmful burning process into a beneficial mechanical punching process. By using a wheel with locating spikes that physically pierces the plastic rather than burning it, the system transforms a harmful thermal process into a clean mechanical process that achieves the same functional result without emissions.
2Manufacturing precision
If a worker manually follows with a gas torch to burn openings, then openings are made at marked points, but extreme arm fatigue and soreness occur from long hours of using the heavy torch
Solution Approach 1:
The patent implements a self-service system where the apparatus automatically performs the opening-making function without requiring manual operation of a heavy torch. The wheel with locating spikes is driven by the movement of the apparatus itself (towed by tractor or self-propelled), and the spacing is automatically controlled by the wheel's geometry and positioning, eliminating the need for a worker to manually guide a torch along the ridge.
Solution Approach 2:
The patent replaces the manual mechanical system of holding and guiding a heavy torch with an automated mechanical system where the opening-making function is integrated into the apparatus structure. The wheel with spikes is fixed to the apparatus framework and automatically contacts the plastic covering at the correct positions as the apparatus moves forward, eliminating arm fatigue from torch handling.
3Productivity
If a tractor-pulled apparatus with automated control system is used, then evenly spaced holes are created efficiently, but device complexity increases with multiple components
Solution Approach 1:
The patent implements multi-functionality by integrating several functions into a single apparatus: the wheel with locating spikes simultaneously serves as the spacing reference, the positioning mechanism, and the opening-making tool. The apparatus can be either tractor-pulled or self-propelled, and the same basic structure performs all functions of measurement, positioning, and plastic penetration, reducing the need for separate components.
Solution Approach 2:
The patent merges the spacing measurement function and the opening-making function into a single integrated mechanism. The wheel with locating spikes combines the spacing control (through its diameter and spike positioning) with the actual plastic-piercing action, eliminating the need for separate marking and burning/punching operations that would require additional components.
4Ease of manufacture
If conventional manual marking and burning process is used, then openings are created in plastic covering, but the process is labor intensive requiring multiple workers
Solution Approach 1:
The patent merges the functions of multiple workers (measuring, marking, and burning/punching) into a single automated apparatus. The wheel with locating spikes performs the spacing and positioning function that would require a first worker, while the integrated punching mechanism performs the opening creation that would require a second worker with a torch, all in a single continuous operation.
Solution Approach 2:
The apparatus is self-sufficient in performing all opening-creation functions without requiring multiple workers. The spacing is automatically controlled by the wheel geometry, the positioning is maintained by the apparatus structure, and the openings are automatically created by the spinning wheel with spikes, making the system self-service and eliminating the need for multiple operators.

AI summary
An apparatus for making holes in plastic along a ridge row has a frame with wheels spanning a ridge row, a furrow reference wheel centered in the frame adapted to roll on soil surface between two raised ridge rows, a first vertically translatable mechanism positioned at a distance to a first side of the furrow reference wheel to be directly over the ridge row adjacent the furrow reference wheel, the vertically translatable mechanism having a first electrically-heated hole punch element at a lower extremity, and a control system having a power supply, sensors and actuators for managing operation of the apparatus. As the apparatus is towed, the furrow reference wheel triggers signals to the control system to activate the vertically translatable mechanism at repeated intervals to descend and make holes in the plastic covering on the raised ridge row.
