Projector Ceiling Hook Mount With Lock Lever and Hidden Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling mounts for projectors and similar pendant structures lack ease and safety in positioning and removal, often requiring complex fixation and visibility of cables.
Innovation Solution
A ceiling mount with a hook and lock lever mechanism that allows easy hanging and secure attachment of projectors, featuring a tubular rod for cable concealment and a lock lever with a biasing element for safe handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple hook structure is used for mounting projectors, then ease of operation is improved, but reliability is worsened due to lack of secure locking
Solution Approach 1:
The lock lever is designed to be movable between a locked position (where it blocks the handle receiving area) and an unlocked position (where it allows handle insertion and removal). This dynamic element enables the hook to transition from a simple hanging structure to a secure locked connection, resolving the contradiction between ease of operation and reliable attachment.
2Ease of manufacture
If cables are exposed outside the mount structure, then ease of manufacture is improved, but object-generated harmful factors worsen due to visibility and potential safety hazards
Solution Approach 1:
The cable guide is integrated within the hollow interior of the rod structure, nesting the cable routing function inside the existing mount body. This eliminates the need for separate external cable management components while hiding cables from view, thereby maintaining ease of manufacture while removing the harmful effect of visible cables.
3Reliability
If a lock lever mechanism is added to secure the projector, then reliability is improved, but device complexity worsens
Solution Approach 1:
The lock lever is integrated directly into the hook structure, with the lever forming part of the same structural assembly. The biased element is incorporated within the hook body, and the handle receiving area is formed as part of the hook geometry. This merging of multiple functions into a single integrated component achieves secure locking while minimizing the increase in device complexity.
4Reliability
If the short arm blocks access to the handle receiving area in the locking position, then reliability is improved, but ease of operation worsens due to additional steps required for release
Solution Approach 1:
The long arm of the lock lever serves as an intermediary element that provides a dedicated interface for the user to interact with the locking mechanism. By providing this external actuation point, the user can easily push the lock lever to the unlocked position without needing to manipulate the handle directly against the blocked short arm, thus maintaining both security and ease of operation.

AI summary
Ceiling mount (1) for a pendant device, such as a projector (23), with a handle (24). The ceiling mount comprises a hook (4) for suspending the handle. The hook may comprise a lock lever (5) which is moveable between a locking position and a release position, and a biasing element (15), such as a torsional spring, biasing the lock lever towards the locking position. The lock lever may for example have a short arm (16) blocking access to the handle receiving area of the hook in the locking position, the short arm being at a distance from the handle during rotation of the lock lever (5) between the locking position and the release position.
