Removable projectile resistant protective shield for desktops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for school safety, such as arming teachers or increasing security presence, cannot fully prevent hostile armed intrusions, necessitating an additional level of protection for students and faculty.
Innovation Solution
A removable projectile-resistant shield for desktops made from materials like ultra-high molecular weight polyethylene, bullet-resistant glass, or polycarbonates, secured with a locking channel mechanism that allows for easy attachment and quick release, providing concealment and protection against bullets and other hazardous objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective shield is permanently fixed to the desktop, then protection reliability is improved, but ease of operation deteriorates because the shield cannot be quickly removed in emergencies
Solution Approach 1:
The protective shield is designed as a separable component that can be detached from the desktop using a channel coupling mechanism. The shield includes coupling edges that engage with channels in the desktop, allowing it to be securely attached when needed and quickly removed when necessary, thus resolving the contradiction between permanent fixation for reliability and removable design for ease of operation.
2Reliability
If the shield is made secure and stable on the desktop, then protection effectiveness is improved, but ease of manufacture deteriorates due to complex installation requirements
Solution Approach 1:
The channel coupling mechanism is designed to be universally applicable to various desktop styles and configurations. The channels can be integrated into different desk types (student desks, teacher desks, conference tables) using standard installation methods, allowing the same shield design to be manufactured and installed across multiple applications without requiring custom solutions, thus improving ease of manufacture while maintaining stability.
3Reliability
If the shield provides complete coverage for maximum protection, then protection reliability is improved, but device complexity increases due to larger size and more attachment points
Solution Approach 1:
The protective shield is divided into modular components with standardized coupling edges that interface with channels at specific locations on the desktop. This segmentation allows the shield to provide comprehensive coverage through multiple discrete attachment points rather than requiring a single complex fixed structure, thereby maintaining protection reliability while reducing overall device complexity through modular design.

AI summary
A bullet resistant protective shield for a desk. The protective shield comprises a shield piece having a first channel coupling mechanism. The first channel coupling includes a substantially horizontal element and a substantially vertical element. The first channel coupling mechanism corresponds to a second channel coupling mechanism on a desktop, which also has a horizontal element and a vertical element. The first horizontal element and the first vertical element define a first channel and the second horizontal element and the second vertical element define a second channel. The first vertical element can be placed in the second channel and the second vertical element can be placed in the first channel thereby removably securing the shield piece to the desktop.
