Projector Housing Recess for Concealed Suspension Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projector installations with suspending attachments often have a poor appearance due to visible brackets, which can disrupt the aesthetic fit of the projector within its installation space.
Innovation Solution
A projector design featuring a housing with a recessed bottom surface, allowing the suspending attachment to be mounted in a lower region, reducing the visibility of internal structures and enhancing the projector's appearance, while maintaining adjustability and optimal image projection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suspending attachment is mounted on the top surface of the housing, then the projector can be easily suspended from the ceiling or wall, but the suspending brackets become visible in the exterior view resulting in poor appearance
Solution Approach 1:
The patent introduces a new spatial dimension by creating a recessed region on the top surface of the housing. This recessed region allows the suspending attachment to be mounted below the top surface plane, effectively moving the attachment from the visible exterior dimension to a hidden interior dimension, thus resolving the contradiction between ease of suspension and appearance.
Solution Approach 2:
The suspending attachment is nested within the recessed region of the housing. The mounting surface is formed at the bottom of the recessed region, allowing the suspending brackets to be concealed inside the housing structure while still maintaining their suspension function, thereby hiding the ugly brackets from external view.
2Shape
If the housing top surface is made recessed to hide the suspending attachment, then the appearance is improved, but the housing configuration becomes more complex
Solution Approach 1:
Instead of making the entire housing complex, the patent applies the recessed structure only to the specific local area where the suspending attachment needs to be mounted. The mounting surface is created locally at the bottom of the recessed region, while the rest of the housing maintains its simple original configuration, thus improving appearance without significantly increasing overall device complexity.
3Volume of moving object
If the receiving part is disposed in a lower region of the housing, then the internal space is used more efficiently and the projector size is reduced, but the mounting process becomes more difficult
Solution Approach 1:
The recessed region and mounting surface are pre-formed as integral parts of the housing structure during the housing manufacturing process. This preliminary action ensures that the mounting interface is already prepared and positioned correctly in the lower recessed region, eliminating the need for complex post-assembly mounting operations and reducing the difficulty of the mounting process while maintaining compact projector size.
