Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional linear design process is used, then design is performed by manufacturer's designer, but the process is inflexible and restricted to predefined sizes and designer's ideas only
Solution Approach 1:
The system enables users to perform design operations directly on their body using projected virtual objects, eliminating the need for designers or complex design software. The body itself becomes the design interface, allowing anyone to create customized patterns without requiring design expertise or access to professional design tools.
Solution Approach 2:
The patent replaces traditional mechanical design tools (sketches, patterns, sizing charts) with a projection-based system that uses light and virtual objects. The design process transitions from manual manipulation of physical or digital design artifacts to interactive projection and detection on the user's body, enabling real-time customization.
2Ease of operation
If t-shirt design machine with remote controllers is used, then user can virtually design t-shirt, but the operation is too complex for ordinary users and interactivity is low
Solution Approach 1:
The patent extracts the control interface from external devices (remote controllers, keyboards, mice) and integrates it directly onto the user's body through projection. The body becomes the control surface, eliminating the need for separate control devices and simplifying operation to natural body movements and positions.
Solution Approach 2:
The projection system acts as an intermediary between the user's body and the design software, translating physical body positions and movements into digital design commands. This intermediary layer enables intuitive interaction without requiring users to learn complex control interfaces or software operations.
3Loss of information
If projection mapping is used for design, then immediate feedback and interactive design are provided, but the system complexity increases
Solution Approach 1:
The system implements real-time feedback by continuously detecting the user's body position and immediately updating the projected virtual objects and resulting pattern design. This closed-loop feedback mechanism allows users to see the effect of their movements instantly, enabling intuitive exploration and precise design control without requiring complex post-processing or interpretation.
Solution Approach 2:
The projection system serves multiple functions simultaneously: it displays virtual objects for interaction, provides real-time feedback on body position, renders the final pattern design, and guides the user through the design process. This multi-functionality consolidates what would otherwise require separate systems into a single integrated apparatus, managing complexity through functional integration.
4Manufacturing precision
If post-production modification with pens or screen printing is used, then design can be modified after production, but the product quality is poor
Solution Approach 1:
The system performs the complete design process before production begins, using projection and body detection to finalize the pattern design in real-time on the user's body. This preliminary design action eliminates the need for post-production modifications, ensuring high quality from the start and preventing defects that would require costly rework or correction.
