Nested Security Gate With Recessed Inner Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security gates lack the ability to provide selective access for different pets and children, as they are designed for single passageways and do not accommodate multiple users or animals effectively.
Innovation Solution
A security gate design featuring an outer frame with an inner gate, where the inner gate has a recess and a door, and projections from the outer gate engage with the recess to support the inner gate, allowing for adjustable access by using multiple locking mechanisms to control passage through both the outer and inner gates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single passageway security gate is used, then the structure is simple, but it cannot provide selective access for different pets and children
Solution Approach 1:
The patent implements a nested gate structure where an inner gate is positioned within the opening of an outer gate. The inner gate has its own frame and can be independently opened and closed, allowing selective access control. This nested configuration enables different users (pets or children) to access different gates based on their size, thereby providing adaptability without requiring completely separate gate structures.
2Reliability
If the inner gate is made secure with locking mechanisms, then safety is improved, but the risk of entrapment between rails increases
Solution Approach 1:
The patent incorporates recesses in the inner gate frame at strategic locations where the rails are positioned. These recesses create localized gaps or relief areas that prevent pets or children from becoming trapped between the rails and the gate frame. By modifying only the critical areas (where entrapment could occur) rather than the entire gate structure, the design maintains security through locking mechanisms while eliminating the entrapment hazard.

AI summary
A security gate including an outer gate and an inner gate for selective passage of people and/or pets therethrough. In one example, the security gate includes: an outer frame; an outer gate at least partially disposed within the outer frame; an inner gate disposed within the outer gate, the inner gate comprising an inner frame having at least one recess; a door at least partially disposed within the inner frame; and at least one projection extending from the outer gate and engaging the at least one recess for supporting the inner gate within the outer gate.
