Bed hood
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal ballistic protection for individuals, especially in rest situations, is inadequate as existing solutions do not provide a secure and comfortable space for sleep while maintaining protection and communication capabilities.
Innovation Solution
A protective bed hood with a constant structure and a movable portion that can extend to form a secure inner space, equipped with ballistic boards, ventilation, and multimedia capabilities, allowing for safe rest and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bed hood structure is provided for ballistic protection, then personal safety is improved, but the complexity of the device increases
Solution Approach 1:
The bed hood is divided into a constant hood structure and a movable portion that can be separated. The constant structure provides the basic protective framework while the movable portion can be extended or retracted as needed, allowing the system to provide full protection when required while maintaining simplicity during normal use.
Solution Approach 2:
The movable portion is designed to slide between a retracted position (adjacent to the constant structure) and an extended position (beyond the opening). This dynamic capability allows the hood to adapt its configuration based on whether protection is needed, reducing complexity during non-critical periods while maintaining full protective capability when threats arise.
2Volume of moving object
If a movable portion is added to extend the hood structure, then the protected space is improved, but the device complexity increases
Solution Approach 1:
The movable portion is sleeved juxtaposed to the constant structure, with the movable portion able to slide along rails that are integrated into the constant structure. When retracted, the movable portion nests within or alongside the constant structure, minimizing its footprint. When extended, it slides outward along the rails to provide additional protected space, allowing volume expansion without proportionally increasing overall structural complexity.
3Reliability
If ballistic protecting boards are installed on the hood structure, then protection capability is improved, but the weight of the object increases
Solution Approach 1:
The hood structure incorporates ballistic protecting boards made from advanced composite materials such as fiberglass, polyethylene, or Kevlar. These materials provide high ballistic protection relative to their weight, offering superior strength-to-weight ratios compared to traditional metals. The composite construction allows the hood to achieve enhanced protection capability while minimizing the weight increase that would result from using denser materials like steel.

AI summary
A protective hood for individuals positioned in hazard areas is provided that comprises a constant hood structure having an opening, wherein the hood structure is configured to accommodate a portion of a bed that partially protrudes through the opening; a closing board outwardly connected to the hood structure and positioned opposite the opening; and a movable portion sleeved juxtaposed to the constant structure, wherein the movable portion is configured to move relative to the constant structure so as to elongate the constant structure from a first position in which the movable portion is fully adjacent to the constant structure and a second position in which the movable portion is extended outwardly beyond the opening so as to cling to the closing board and form a protected and secure inner space.
