Projector Interface Layout With Unified Focus and Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectors are not user-friendly due to the operation unit, connector unit, and focus adjustment lever being arranged at different faces of the casing, lacking a unified interface for user interaction.
Innovation Solution
The focus lever, press button, and coupling terminal are integrated on a single wall section of the projector casing, with recessed arrangements and a removable cover to conceal and organize these components, enhancing user accessibility and design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation unit, connector unit, and focus adjustment lever are arranged at different faces of the casing, then each component can be independently positioned, but the projector becomes less user-friendly and requires users to access multiple faces for basic operations
Solution Approach 1:
The patent consolidates the operation unit, connector unit, and focus adjustment lever onto a single face section of the projector casing. This merging of previously distributed components into one location improves ease of operation by allowing users to access all essential functions from one side, eliminating the need to reach around or access multiple faces during normal use
2Ease of operation
If multiple components are concentrated on a single face section, then user accessibility is improved, but the face section may become cluttered and protrude
Solution Approach 1:
The patent employs a cover that can be attached to or removed from the face section, creating a nested structure where the cover encloses the operation unit, connector unit, and focus adjustment lever. When attached, the cover maintains a sleek casing profile by concealing the components and preventing protrusion, while still allowing access when removed or opened
3Ease of operation
If the connector unit and operation buttons are provided at the same face section as the focus adjustment lever, then all user interactions are unified, but the face section requires careful design to avoid clutter
Solution Approach 1:
The patent divides the face section into distinct regions or zones, with the cover serving as a separate segment that can be independently managed. This segmentation allows each component (operation unit, connector unit, focus adjustment lever) to have its own designated space, organizing them systematically rather than creating a cluttered arrangement

AI summary
A projector includes: an exterior casing having a first wall section; a projection optical part accommodated in the exterior casing and having a lens group projecting image light onto a projection surface; a focus lever moving a position of the lens group; a power switch being pressed to generate a control signal; and a coupling terminal electrically coupled to a cable transmitting an electrical signal. The focus lever, the power switch, and the coupling terminal are arranged at the first wall section.
