Projector Interaction Module Mounting for Tool-Free Cleaning Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interaction modules for controlling appliances via projected images on kitchen surfaces are difficult to clean and maintain, particularly in soiled environments, as they require removal from mounting surfaces for maintenance and hygiene purposes.
Innovation Solution
An interaction module with a housing and mounting plate design that allows secure attachment and easy release without tools, featuring a form-fit engagement system and a locking facility to prevent accidental detachment, along with a power lead configuration that ensures secure retention and easy maintenance, including a design that prevents inadvertent release and facilitates cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the interaction module is securely mounted to the underside of a wall cupboard, then the module remains stable and prevents accidental release, but the module becomes difficult to remove for cleaning and maintenance
Solution Approach 1:
The mounting system is divided into separate components: a mounting plate that attaches to the wall cupboard and a housing that attaches to the mounting plate. This segmentation allows the housing to be easily removed from the mounting plate for cleaning while the mounting plate remains securely fixed to the wall cupboard, thus maintaining mounting stability while improving removal ease.
Solution Approach 2:
The mounting system transitions from a static permanent fixation to a dynamic reversible connection. The form-fit engagement with hooked segments and corresponding holders allows the housing to be easily attached and detached multiple times, providing both secure mounting during operation and easy removal for maintenance without compromising stability.
2Reliability
If the housing is permanently fixed to the mounting plate, then the module prevents accidental release and ensures reliable operation, but the module cannot be easily removed for cleaning in soiled environments
Solution Approach 1:
The system separates the housing (requiring cleaning) from the mounting plate (remaining in place). The housing can be easily detached from the mounting plate through the form-fit engagement mechanism, allowing users to clean the housing in soiled kitchen environments while the mounting plate remains securely attached to prevent accidental release.
Solution Approach 2:
The mounting system is designed to be user-operable without tools. Users can easily attach and detach the housing from the mounting plate by hand, enabling self-service cleaning and maintenance while the mounted configuration provides reliable operation and prevents accidental release during normal use.
3Ease of operation
If the mounting system allows easy tool-free attachment and detachment, then the module can be easily removed for maintenance, but the retention security and resistance to accidental release may be compromised
Solution Approach 1:
The mounting system uses a dynamic form-fit engagement mechanism with hooked segments and corresponding holders that provides both easy tool-free attachment/detachment and secure retention. The geometric interlocking design ensures that once attached, the housing is securely retained and resistant to accidental release, while still allowing intentional easy removal when needed for maintenance.

AI summary
An interaction module includes a housing for holding a projector to project an image onto a working surface and an optical scanning device for scanning a gesture in the region of the image, and a mounting plate configured for fastening to an underside of an object attached above the working surface. The mounting plate is configured for attachment of the housing on a side of the mounting plate which side faces away from the object.
