Double Door Gate Apparatus With Segmented Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional residential gates are typically single gates, which can be cumbersome and inefficient in terms of space management and accessibility, as they require a larger opening size and restrict access to specific areas when swung open.
Innovation Solution
A double door gate apparatus featuring two pivotally mounted gates that swing inward and are vertically liftable, allowing for independent operation and concurrent opening, with a latch mechanism and stop system to regulate access and size of the opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single gate is used, then the gate structure is simple, but the gate requires a larger opening size and restricts access to specific areas when swung open
Solution Approach 1:
The gate system is divided into two separate gates (first gate and second gate) that can operate independently. Each gate can be opened or closed separately, allowing flexible control over access to different areas. This segmentation enables the system to provide varied access patterns (both gates closed, one gate open, or both gates open) without requiring a large single opening.
2Ease of operation
If a single gate is used, then the gate structure is simple, but the gate becomes cumbersome in terms of space management and accessibility
Solution Approach 1:
By dividing the gate system into two independent gates, each gate can be smaller and easier to operate individually. The gates can be opened separately based on specific needs, reducing the effort required compared to moving a single large gate. Each gate's reduced size and weight make them more manageable while providing flexible access control.
Solution Approach 2:
The gate system incorporates dynamic characteristics by allowing the gates to be opened independently based on operational requirements. The gates can swing open to different extents and be controlled separately, providing adaptability in space management and accessibility without requiring complex mechanical systems.
3Adaptability or versatility
If two gates are introduced, then access control flexibility is improved, but the operational process becomes more complex
Solution Approach 1:
The gate system is segmented into two independently operable gates, each capable of being opened or closed based on specific access requirements. This segmentation allows for simplified operational logic where each gate can be controlled separately without requiring coordination between the two gates, reducing operational complexity despite the increased flexibility.

AI summary
A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.
