Vertical Projector Housing Stability and Control Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Horizontal projectors become unstable when used vertically due to positional deviation of controls, leading to operational challenges and potential instability.
Innovation Solution
A projector design with a housing having a base and side face where the side face area is greater than the base area, featuring a light projection port on the top face and an operation unit with controls movable in an upward/downward direction to prevent positional deviation and ensure stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If controls are disposed on a horizontally-extended face of a horizontal projector, then ease of operation is improved, but stability deteriorates when the projector is used vertically
Solution Approach 1:
The patent applies asymmetry by inverting the traditional horizontal projector configuration to a vertical configuration, where the side face area is greater than the base area. The operation unit with pressable controls is disposed on the top face rather than a horizontal extended face, creating an asymmetric layout that maintains operational ease while achieving vertical stability.
Solution Approach 2:
The patent implements inversion by transforming the projector from a horizontal orientation to a vertical orientation. The operation unit is moved from a horizontal extended face to the top face, and the pressable controls are designed to be movable in an upward/downward direction instead of the conventional horizontal pressing motion, effectively applying the 'other way round' principle to resolve the stability issue.
2Adaptability or versatility
If the projector is transformed from horizontal to vertical configuration, then adaptability is improved, but housing stability deteriorates due to control position deviation
Solution Approach 1:
The patent creates an asymmetric vertical configuration where the side face area exceeds the base area, allowing the projector to adapt to vertical mounting scenarios while maintaining structural stability through the repositioned operation unit on the top face.
Solution Approach 2:
The projector design achieves universality by enabling both horizontal and vertical usage configurations. The operation unit designed with upward/downward movable controls on the top face allows the device to function effectively in vertical orientation, while the overall structure can still accommodate horizontal placement, thus providing multi-functional adaptability.
3Ease of operation
If pressable controls are disposed on a vertical face for vertical projector use, then ease of operation is maintained, but housing stability deteriorates due to positional deviation
Solution Approach 1:
Instead of placing controls on a vertical face as initially considered, the patent inverts the approach by positioning the operation unit on the top face with controls that move in the upward/downward direction. This inverted configuration maintains operational ease while preventing the positional deviation that would compromise housing stability.

AI summary
A projector includes a housing, an image projection unit, and an operation unit. The housing has a base and a side face. The side face has an area greater than an area of the base. A light projection port is disposed in a top face of the housing. The image projection unit, encased within the housing, projects light corresponding to image data via the light projection port. The operation unit, disposed on a top face of the housing, includes a first pressable control moveable in an upward/downward direction.
