Vacuum cleaner with projected display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face challenges in displaying operational information effectively, as projections on the floor surface are often unreadable due to distance, floor texture, and interference from furniture, and require complex equipment that limits compatibility with different cleaner heads.
Innovation Solution
A vacuum cleaner design featuring a projection surface on the tool, allowing users to read information without losing focus on the cleaning area, with the projector located near the main body, enabling compatibility with various cleaner heads and adjustable for different modes and user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the projection system is integrated into the cleaner head, then the information is displayed close to the cleaning area, but the device complexity and cost increase significantly
Solution Approach 1:
The projection system is extracted from the cleaner head and relocated to the main body of the vacuum cleaner. This separation removes the complex electronic equipment from the cleaner head, simplifying its structure while maintaining the information display functionality through the projection surface on the main body.
Solution Approach 2:
A projection surface is introduced as an intermediary element that transmits information from the projector (located on the main body) to the user. This mediator allows the information to be displayed in a location that is both accessible to the user and does not require complex electronics in the cleaner head.
2Loss of information
If the projection system is integrated into the cleaner head, then the information is displayed near the cleaning area, but the adaptability with different cleaner heads is reduced
Solution Approach 1:
By extracting the projection system from the cleaner head and placing it on the main body, the cleaner head design is freed from this constraint, allowing different types of cleaner heads to be used without being limited by the presence of a built-in projection system.
Solution Approach 2:
The projection system on the main body serves as a universal information display solution that works with various cleaner heads, making the system more versatile and adaptable to different cleaning needs and attachments.
3Loss of information
If the projection is displayed on the floor surface, then the information is shown in the cleaning area, but the readability is reduced due to distance and floor characteristics
Solution Approach 1:
Instead of projecting information directly onto the floor surface (two-dimensional display in the cleaning area), the invention uses a projection surface on the main body that presents information in a different spatial dimension, closer to the user's line of sight and independent of floor characteristics.
Solution Approach 2:
The information is copied from the projector onto a dedicated projection surface on the main body, rather than being displayed on the floor surface. This copy is presented in a location with controlled viewing conditions, improving readability while maintaining the informational content.
4Device complexity
If the projector is located on the main body, then the device complexity is reduced, but the information may be harder to read while maintaining focus on the cleaning area
Solution Approach 1:
The projection surface on the main body acts as an intermediary that makes the information from the projector accessible to the user. Even though the projector is on the main body, the projection surface positions the information in a location that does not obstruct the user's view of the cleaning area while remaining readable.
Applied Scientific Principles
