Ceiling-Mounted Access Gate for Flexible Lobby Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control gates, such as turnstiles, have a large footprint and are inflexible, requiring early installation in construction and making relocation difficult, which is problematic in spaces like high-rise buildings.
Innovation Solution
An access control gate with poles attached to the ceiling, allowing for flexible positioning and easy relocation, featuring quick-release means and ceiling-mounted power supply, enabling movement between operative and storage positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access control gates are attached to the floor with steel tubes, then the gates are securely fixed, but the gates cannot be easily relocated and form obstacles during construction and renovation
Solution Approach 1:
The patent transitions from floor-mounted (horizontal plane) to ceiling-mounted (vertical plane) installation. The access control gate is attached to the ceiling via a pole that extends downward, utilizing the vertical dimension to resolve the contradiction between secure fixation and relocatability. This dimensional change allows the gate to be firmly anchored while remaining easily removable and repositionable.
Solution Approach 2:
The patent inverts the conventional mounting approach by attaching the access control gate to the ceiling rather than the floor. This inversion eliminates the need for embedded steel tubes in the floor, removes obstacles during construction, and enables easy relocation by simply detaching and reattaching the pole to the ceiling.
2Adaptability or versatility
If access control gates are installed early in construction, then they can be securely integrated into the building structure, but they cannot be moved or removed later
Solution Approach 1:
The patent implements a dynamic installation system where the access control gate can transition between fixed and movable states. The ceiling-mounted pole allows the gate to be securely fixed during operation but easily removed and relocated when needed, providing temporal flexibility without requiring substantial reconstruction work.
3Reliability
If access control gates have a large footprint, then they provide adequate security and control functionality, but they consume valuable lobby space in high-rise buildings
Solution Approach 1:
By mounting the access control gate from the ceiling rather than the floor, the patent utilizes vertical space to reduce the horizontal footprint. The pole extends vertically from the ceiling to the floor level, allowing the gate to maintain its security functionality while occupying minimal lobby space.

AI summary
The access control gate (1) for controlling flow of people in a building comprises at least one pole (2a, 2b) having a first end and a second end, and access control means (3a, 3b) configured to control access through the access control gate (1). The first end of the pole (2a, 2b) is configured to be attached to the ceiling (4) of the building and the access control gate (1) is configured to be moveable between at least a first position and a second position, wherein at least one of said positions is an operative position and the other position is an operative position or a storage position.
