Impact Dampening Fixture with Segmented Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to provide an effective and cost-efficient means to protect windows and doors from damage due to vandalism or storms, as they lack a reliable impact dampening mechanism.
Innovation Solution
An impact dampening device comprising a fixture with an attachment mechanism, a mounting device with a protective panel, and dampening bars featuring alternating rigid and less rigid sections, along with impact-absorbing bumpers, to absorb and distribute forces applied to the panel, thereby reducing impact on the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective barrier is added to windows and doors, then protection from vandalism and storms is improved, but cost and device complexity increase
Solution Approach 1:
The protective barrier is divided into multiple dampening bars that can be independently attached to the structure. Each bar functions as a separate protective element, allowing the system to provide comprehensive protection while maintaining modular simplicity for installation and replacement.
Solution Approach 2:
The dampening bars utilize composite construction with rigid portions for structural strength and less rigid dampening portions for impact absorption. This combination of materials with different properties enables the barrier to both withstand and dissipate impact forces effectively.
2Reliability
If impact absorption is enhanced through dampening mechanisms, then protection effectiveness is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The dampening bars feature localized variations in rigidity, with rigid portions positioned at attachment points and less rigid dampening portions positioned at impact zones. This local differentiation of material properties enables targeted impact absorption without requiring complex manufacturing throughout the entire structure.
Solution Approach 2:
The dampening portions are designed with altered physical parameters (reduced rigidity) compared to the rigid portions. This parameter change allows the same basic bar structure to perform both structural support and impact dampening functions through simple geometric or material property modifications rather than complex manufacturing processes.
3Reliability
If a protective panel is mounted on the dampening fixture, then impact distribution is improved, but ease of installation and operation deteriorates
Solution Approach 1:
The protective system is segmented into the dampening fixture with attached bars and the separate protective panel. This segmentation allows the dampening mechanism to be pre-assembled and installed independently, then the panel can be added or removed as needed, simplifying installation while maintaining impact distribution capabilities.
Solution Approach 2:
The dampening fixture serves as an intermediary component between the structure and the protective panel. It provides the mounting interface and impact absorption mechanism, allowing the panel to be easily attached and detached while the complex dampening function remains integrated into the fixture.

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 device effectively reduces impact on structures like glass windows or doors by distributing forces through its dampening mechanism, providing a cost-effective and efficient protection against vandalism and storm-related damage.
Implementation Method 1
the dampening fixture dampens a force applied to the protective panel to reduce or eliminate impact on the structure
Implementation Method 2
the dampening bars may include rigid portions that are intermittently disposed with less rigid, dampening portions
Implementation Method 3
the mounting device includes an impact absorbing bumper disposed between the panel and the dampening fixture
