Projector Power Adapter for Flexible Ceiling or Stand Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector installation technologies lack flexibility, as they require a ceiling with a power outlet for ceiling installation and cannot be readily installed without a fixed point or power supply on the ceiling.
Innovation Solution
An adapter system with first and second electric terminals allows for detachable attachment to both wall and stand contacts, enabling flexible installation of projectors by supplying electricity through these terminals to the projector, whether mounted on a ceiling or a stand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the projector is fixed to the ceiling via a hook plug for power supply, then the projector can receive power for driving, but the projector can be installed only at the ceiling
Solution Approach 1:
The power supply system is segmented into separate components: a power supply unit with electric contacts and a power receiver unit with corresponding terminals. This allows the power supply function to be separated from the ceiling structure, enabling the projector to receive power through detachable connections rather than fixed ceiling mounting.
Solution Approach 2:
The power connection transitions from a fixed ceiling-mounted hook plug to a dynamic, detachable connection system. The power receiver unit can be moved between different locations (ceiling, stand, table) and connected to the power supply unit as needed, providing flexible and adaptable installation options.
2Ease of operation
If the projector is placed on a swingable frame for angle adjustment, then the projector can be positioned at different angles, but the projector cannot be readily installed at the ceiling when no power supply outlet or fixed point is available
Solution Approach 1:
The power supply system is designed with universal adaptability to work with multiple installation configurations. The power receiver unit can be mounted on various surfaces (ceiling, stand, table) and connected to the power supply unit through detachable electric contacts, making the system universally applicable regardless of the specific installation location or angle adjustment mechanism.
3Adaptability or versatility
If the ceiling has no portion to which the projector is fixed or no power supply outlet, then installation flexibility is reduced
Solution Approach 1:
The power receiver unit acts as an intermediary between the projector and various power supply locations. It can be mounted on different surfaces (ceiling, stand, table) and connected to the power supply unit through detachable electric contacts, bridging the gap between the projector and power source regardless of ceiling availability or configuration.

AI summary
An adapter includes a first terminal attachable to and detachable from an electric contact provided at a ceiling and an electric contact provided at a stand, and a second terminal coupled to a projector that projects image light. The second terminal supplies electricity via the first terminal to the projector.
