Projection Optical Apparatus Grip and Flange Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing size of projection optical apparatuses has made them difficult to handle, both during installation and removal from projectors, necessitating a solution for easier gripping and handling.
Innovation Solution
A projection optical apparatus with a lens barrel that holds multiple lenses and includes grips extending outward from the barrel, allowing for easy gripping and handling, as well as a flange that protrudes to absorb impact and prevent damage to the lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the projection optical apparatus is made larger to include more lenses and components, then the projection quality and functionality are improved, but the ease of handling and gripping deteriorates
Solution Approach 1:
The projection optical apparatus is divided into a lens barrel section containing the optical components and a separate grip section that can be attached or detached. This segmentation allows the optical system to maintain its size for projection quality while the grip section provides easy handling when needed.
Solution Approach 2:
A grip is introduced as an intermediary component between the user's hand and the lens barrel. The grip acts as a mediator that provides ergonomic handling without requiring the lens barrel itself to be redesigned, thus preserving projection quality while improving ease of operation.
2Adaptability or versatility
If the projection optical apparatus is made larger with more components, then the projection functionality is improved, but the difficulty of installation and removal from projector increases
Solution Approach 1:
The projection optical apparatus is segmented into a lens barrel section and a grip section. The lens barrel section contains all necessary optical components for projection functionality, while the grip section is separable. This allows the apparatus to maintain full projection functionality while enabling easier installation and removal by providing a convenient gripping point.
Solution Approach 2:
The grip is designed to be detachable from the lens barrel, providing dynamic adaptability. During installation or removal, the grip can be detached to reduce handling complexity. During normal operation, the grip can be reattached for stable positioning, thus improving ease of installation without compromising projection functionality.
3Reliability
If the lens barrel is made more robust to protect lenses, then the reliability is improved, but the ease of gripping deteriorates
Solution Approach 1:
The apparatus is segmented into the lens barrel section that provides robust protection for the lenses and a separate grip section that provides ergonomic handling. The grip section can be designed with soft, grippable materials while the lens barrel maintains its protective, robust structure, thus resolving the contradiction between protection and ease of gripping.
Solution Approach 2:
The grip acts as an intermediary between the user and the robust lens barrel. It provides a comfortable gripping surface without requiring the lens barrel itself to be made less robust, thus maintaining lens protection while improving ease of gripping.
4Ease of operation
If additional components such as grips are added to the lens barrel, then the ease of handling is improved, but the device complexity increases
Solution Approach 1:
The grip is designed as a detachable component rather than a permanent attachment. This dynamic design allows the grip to be added when handling is needed and removed when not needed, thus improving ease of handling without permanently increasing device complexity. The simple attach/detach mechanism minimizes the added complexity.
