Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a user cleans the image capturing surface by him/herself, then the cleaning cost is reduced, but the risk of damaging the image capturing surface increases
Solution Approach 1:
The patent replaces manual mechanical cleaning operations with an automated cleaning apparatus that uses controlled air blowing and adhesive sheets to remove foreign particles, eliminating the need for users to manually touch or wipe the image sensor surface, thus preventing damage while maintaining cleaning effectiveness
Solution Approach 2:
The invention introduces an intermediary cleaning apparatus between the user and the image sensor, where the apparatus performs the cleaning function using specialized mechanisms (air blowing, adhesive sheets) that are designed to be safe for the detection surface, thereby mediating the interaction and preventing direct damage
2Manufacturing precision
If a trained operator cleans the imaging surface at a service store, then the cleaning quality is improved, but the cleaning cost and time increase
Solution Approach 1:
The patent enables self-service cleaning by providing an automated apparatus that users can operate themselves without requiring trained operators, achieving consistent cleaning quality through automated control mechanisms while eliminating the need to transport devices to service stores
Solution Approach 2:
The invention replaces the skill-dependent manual cleaning process with an automated system that uses controlled air blowing and adhesive sheet mechanisms, eliminating variability in cleaning quality based on operator skill while reducing cleaning time and cost
3Ease of operation
If existing cleaning apparatuses are used, then the cleaning process is simplified, but the precision and versatility in removing foreign particles deteriorates
Solution Approach 1:
The patent segments the cleaning function into multiple specialized cleaning members (air blowing mechanism, adhesive sheet mechanism) that can be selectively applied based on the type of foreign particles, achieving high precision removal while maintaining ease of operation through automated selection and application
Solution Approach 2:
The invention creates a multi-functional cleaning apparatus that can handle various types of foreign particles (large solids, adhesive oils, fine dust) using different cleaning mechanisms, providing both precision and versatility while maintaining simple operation through automated control
4Manufacturing precision
If cleaning apparatuses are designed for specific detection elements, then the cleaning precision is improved, but the adaptability to various detection elements deteriorates
Solution Approach 1:
The patent designs a universal cleaning apparatus with adjustable cleaning members and multiple cleaning mechanisms that can adapt to different types and sizes of detection elements, maintaining high cleaning precision through adjustable parameters while providing broad adaptability across various detection device formats
