Grooved Protective Ionizer for Static Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Static eliminators are ineffective when a charged object is in contact with or close proximity to another object, as the voltage field is induced towards the other object, leaving no voltage available for neutralization on the upper side, and existing solutions interfere with the movement of sheets or wear out quickly.
Innovation Solution
A protective ionizing device with a series of grooves and electrically conductive microfibers suspended just below the surface, which ionizes air to remove or reduce static charge without interfering with the movement of sheets or wearing out, using a wire core and microfibers made from conductive materials like carbon or stainless steel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a static eliminating cord or rod is placed below the sheet, then it can eliminate induced voltage, but it interferes with the sheet's ability to move across the surface
Solution Approach 1:
The patent segments the static elimination function into multiple discrete ionizing points distributed across the surface, rather than using a single cord or rod. This segmentation allows the ionizing points to be positioned in grooves or recesses, eliminating interference with sheet movement while maintaining effective coverage across the entire surface area.
2Reliability
If static eliminating tape is used under the sheet, then it can eliminate static, but the tape gets abraded, damaged, or becomes ineffective after use
Solution Approach 1:
The patent introduces grooves or recesses as an intermediary structure that protects the ionizing points from direct contact and abrasion by the sheet. The ionizing points are positioned within these protective grooves, allowing them to function effectively while being shielded from mechanical damage, thereby extending their service life.
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
Efficiently eliminates static on the surface side of sheets without compromising workflow or machine functionality, reducing issues like jamming and cling, and extends the life of ionizing points by protecting them from abrasion.
Implementation Method 1
air between the ionizing points and material passing by the upper surface is sufficiently ionized to remove or reduce static charge from the material

AI summary
The present invention relates to a protective ionizing device, or protective static eliminator, and methods, systems, apparatus and kits using the device. The device has a surface having a series of (e.g., one or more) grooves or gaps, each groove defines a space; and a multiplicity of ionizing points suspended in the space, just below the upper surface of the device. The ionizing points can be suspended on braided microfibers, on an extruded surface in the groove, on an elastic cord, or on a wire core.The device is useful for the efficient elimination of static charge build-up on a surface of insulative material while maintaining and protecting the ionizing points.
