Striker Plate Reinforcement for Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current window lock assemblies struggle to effectively resist large impact forces, such as those from heavy objects or accidental falls, while maintaining cost-effectiveness and safety, especially in preventing unintentional opening from the inside.
Innovation Solution
A striker plate with a reinforcement arrangement integrated into its abutment element, providing enhanced counteracting forces when locked, combined with a lock assembly featuring moveable locking pawls that engage the abutment area, allowing for improved resistance to opening attempts both intentionally and unintentionally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional striker plate without reinforcement is used, then the structure is simpler and cost is lower, but the capacity to resist large impact forces is insufficient
Solution Approach 1:
The reinforcement arrangement is integrated directly into the striker plate as a single-piece element, merging the reinforcement function with the existing structure. This eliminates the need for separate reinforcement components while maintaining the enhanced capacity to resist impact forces.
Solution Approach 2:
The striker plate is divided into functional zones: a base portion for attachment and a reinforced abutment element for impact resistance. The reinforcement arrangement creates a localized strengthened region at the critical abutment area, providing targeted strength enhancement without unnecessarily complicating the entire structure.
2Ease of manufacture
If a single-part striker plate solution is used, then manufacturing and assembly are simplified, but the counteracting force distribution is insufficient
Solution Approach 1:
The reinforcement arrangement is combined with the abutment element in a single integrated component. This merging maintains the simplicity of single-part construction while the reinforced geometry provides superior force distribution compared to a non-reinforced design.
Solution Approach 2:
The reinforcement arrangement is strategically positioned at the abutment element where impact forces are applied. This localized reinforcement provides enhanced force distribution at the critical stress point while keeping the rest of the striker plate simple and easy to manufacture.
3Reliability
If the striker plate uses multiple fasteners for secure attachment, then the attachment reliability is improved, but the device complexity increases
Solution Approach 1:
The striker plate is segmented with multiple throughgoing openings distributed across its base, allowing for multiple fasteners. This segmentation enables reliable attachment through multiple attachment points while maintaining a simple overall design that does not require complex fastening mechanisms.
