Insulating Frame for Dropped Ceiling Grid Electrical Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Workers accessing dropped ceiling grids face risks of electric shock due to exposed high-voltage wiring, despite safety codes, as conventional safety devices are cumbersome, inconvenient, and limit maneuverability.
Innovation Solution
An electrically insulating frame is designed to attach to dropped ceiling grid cells, fully enclosing the opening to prevent electrical contact, allowing workers to extend through it while insulated from potential high-voltage equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wearable grounding devices are used to protect workers, then electrical safety is improved, but the devices become cumbersome, bulky, and limit maneuverability
Solution Approach 1:
The patent introduces an insulating frame as an intermediary barrier between the worker and exposed electrical wiring. Instead of requiring the worker to wear grounding devices, the frame creates a physical and electrical insulation boundary that protects the worker while allowing free movement and access to the work area.
2Reliability
If building codes prohibit exposed high voltage equipment, then worker safety is improved, but equipment can still become exposed due to deterioration, moisture, rusting, and human error
Solution Approach 1:
The insulating frame serves as a preventive protective measure installed before electrical hazards can occur. By enclosing the opening with insulating material, the system proactively protects workers from potential exposed wiring caused by future deterioration, moisture, or human error, rather than relying solely on code compliance.
3Productivity
If workers remove ceiling tiles to access wiring, then task performance is improved, but the risk of electrical contact increases
Solution Approach 1:
The insulating frame acts as a mediator that allows workers to access the plenum space for task performance while simultaneously blocking the harmful electrical contact pathway. The frame enables productive work access without compromising safety.
4Reliability
If wearable safety devices are complex to install, then safety protection is improved, but installation time and complexity increase
Solution Approach 1:
The patent extracts the safety function from complex wearable devices and relocates it to a simple, stationary insulating frame structure. This extraction simplifies the safety solution from something workers must wear and manage to a passive protective barrier that requires minimal installation and no user action.

AI summary
An electrically insulative frame configured for attachment to a dropped ceiling grid, having a plurality of cells formed by cell members, including an open cell having a cell opening. The frame insulates the cell opening when attached therein. A worker, having a head and torso, may extend his/her head and torso through the frame while being electrically insulated from the cell.
