Static Cling Pickguard for Stringed Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stringed instruments face damage to their delicate finishes due to handling and strumming, with existing pickguards being rigid, requiring fasteners, and being time-consuming to install or replace, while also limiting aesthetic customization.
Innovation Solution
A removable and reattachable plastic cover with static cling properties, designed to fit over the instrument's body or pickguard, featuring a graphic design and allowing for easy interchange without tools or disassembly, maintaining a thin profile to avoid raising the strings' position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a rigid pickguard is used to protect the instrument finish, then protection from abuse is improved, but device complexity and installation time increase due to requiring fasteners and disassembly
Solution Approach 1:
The patent replaces the mechanical fastening system (screws, clips, or adhesive) with an electrostatic adhesion system. The pickguard contains electrostatically charged particles that generate electrostatic attraction to the instrument body, eliminating the need for mechanical fasteners and enabling tool-free installation and removal while maintaining protection functionality
Solution Approach 2:
The patent changes the physical state of the pickguard by incorporating electrostatically charged particles that can be activated or deactivated. When activated, the electrostatic charge provides strong adhesion for protection; when deactivated, the adhesion is reduced allowing easy removal. This parameter change enables the pickguard to transition between attached and detached states without mechanical fasteners
2Strength
If a thick pickguard is used to provide durable protection, then strength and protection are improved, but the strings' position is raised which alters the instrument setup
Solution Approach 1:
The patent employs a thin-film pickguard construction that provides sufficient protection without the thickness of traditional rigid pickguards. The electrostatically charged particles are distributed within a thin layer that maintains structural integrity while keeping the profile low enough to avoid raising string position, thus preserving the instrument's original setup
3Reliability
If a permanent pickguard is used to protect the finish, then reliability of protection is improved, but adaptability and aesthetic customization are reduced
Solution Approach 1:
The patent makes the pickguard dynamic by enabling easy attachment and detachment through electrostatic control. Users can attach the pickguard when protection is needed and remove it when aesthetic customization is desired, allowing the instrument to adapt between protected and customized states. This dynamic capability provides both reliable protection when attached and full aesthetic freedom when removed
Solution Approach 2:
The patent segments the pickguard into a separate, removable component that can be independently attached or removed from the instrument body. This segmentation allows the pickguard to function as a standalone protective element that does not permanently alter the instrument's appearance, enabling users to customize the instrument's aesthetic by choosing different pickguard designs or removing them entirely
4Reliability
If multiple fasteners are used to secure the pickguard, then reliability of attachment is improved, but ease of operation and installation time are worsened
Solution Approach 1:
The patent replaces mechanical fasteners (screws, clips, or adhesive) with an electrostatic adhesion system. The electrostatically charged particles generate sufficient holding force to secure the pickguard reliably during normal use, yet allow easy removal by deactivating or discharging the electrostatic field, eliminating the need for tools and complex fastening operations
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 cover effectively protects the instrument's finish from abuse, allows for quick and easy installation or replacement, and provides customizable aesthetic options without altering the instrument's setup or damaging it.
Implementation Method 1
a configured plastic sheet having a static cling property to facilitate removable securance of the cover to the top of the preassembled stringed instrument

AI summary
A cover 78d, having a static cling property, is formed in a cover perimeter pattern, and with a plurality of holes 82b, 84b, 98b and 100b in accordance with a cover hole-location pattern. The cover 78d is formed from a clear plastic static cling sheet 80, or a white plastic static cling sheet, each having a thickness of 7.5 mil, and may have a decorative design 110 applied to one surface thereof. In a preassembled guitar 48, strings 64 are located over a body top 52, with pickups 56 extending outward from the body top toward, but spaced from, the strings by a pickup-to-strings space, which is greater than 7.5 mil. While the guitar remains preassembled, the cover 78d can be moved into the pickup-to-strings space, and into static clinging engagement with the body top 48.
