Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If movable parts are included in cavities of the core, then protrusion density increases and product delivery improves, but device complexity increases
Solution Approach 1:
The movable parts are nested within cavities of the core structure, allowing the applicator to achieve enhanced protrusion density and product delivery while maintaining a compact integrated design. The movable parts are positioned inside the core's cavities, creating a nested configuration that improves functionality without proportionally increasing overall device complexity.
Solution Approach 2:
The movable parts are designed to move relative to the core, introducing dynamic elements that enhance product delivery and protrusion density. This dynamic capability allows the applicator to adapt during use, improving mascara application effectiveness while the movement is constrained within the cavity boundaries to control complexity.
2Quantity of substance
If multiple cavities and moving parts are used, then product charge and delivery are improved, but manufacturing complexity increases
Solution Approach 1:
The applicator is segmented into multiple functional zones with multiple cavities distributed along the core, each capable of holding and delivering cosmetic product. This segmentation allows for increased product charge capacity while organizing the structure into repeatable modular units that can simplify manufacturing through standardized cavity designs.
Solution Approach 2:
The multiple cavities and movable parts are designed to perform universal functions of product storage and delivery across different sections of the applicator. Each cavity-movable part combination serves the same dual purpose, allowing for standardized manufacturing processes that can produce multiple identical components, thereby reducing overall manufacturing complexity despite the increased number of elements.
3Adaptability or versatility
If movable parts are made free to pivot in all directions, then application flexibility is improved, but control over moving part position is reduced
Solution Approach 1:
The movable parts are designed with flexible characteristics that allow them to pivot and adapt to different application angles and positions. This flexibility enables the applicator to conform to various eyelash configurations and application preferences, improving adaptability while the flexible design itself provides inherent position control through elastic restoration.
Solution Approach 2:
The movable parts are designed to change their orientation and position parameters dynamically during application, allowing pivoting in multiple directions to adapt to different application needs. Simultaneously, the cavity constraints and retaining means modify these parameters by limiting the range of motion, thereby maintaining position control while preserving application flexibility.
