Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional separate hair rollers are used, then each roller can be independently positioned, but it is challenging to position them correctly in the user's hair to achieve desirable hairstyles
Solution Approach 1:
The patent combines multiple separate hair rollers into a single integrated assembly with a common handle and strap system. This merging allows the rollers to be positioned simultaneously as a unit, greatly improving ease of positioning while maintaining the ability to achieve various hairstyles through the coordinated arrangement of multiple rollers in the assembly.
Solution Approach 2:
The hair roller assembly is segmented into multiple independent rollers that can be selectively positioned at different locations in the user's hair. Each roller within the assembly can be independently adjusted and positioned, allowing for versatile hairstyle creation while the overall assembly structure provides ease of handling and positioning.
2Adaptability or versatility
If a fixed-length strap is used to join rollers, then the structure is simple, but it cannot accommodate different head sizes or styling preferences
Solution Approach 1:
The strap connecting the rollers is designed with adjustable length capability, transforming it from a static fixed-length component to a dynamic adjustable component. This allows the strap length to be modified according to different head sizes and styling preferences, improving adaptability while the adjustment mechanism remains relatively simple.
Solution Approach 2:
The adjustable strap serves multiple functions: it connects the rollers together, accommodates different head sizes, and allows for various styling configurations. This multi-functionality increases adaptability without requiring multiple separate devices, keeping the overall structure relatively simple.
3Adaptability or versatility
If rollers are permanently attached to the strap, then the structure is simple, but it lacks versatility for different usage modes
Solution Approach 1:
The roller attachment mechanism is segmented to allow individual rollers to be selectively removed and reattached. This segmentation enables different usage modes where users can configure the number and position of rollers according to their styling needs, providing versatility while keeping each individual attachment point relatively simple.
Solution Approach 2:
The roller attachment system transitions from a static permanent attachment to a dynamic removable and reattachable connection. This allows the configuration of the roller assembly to be changed for different usage modes and styling preferences, improving versatility without requiring a complex mechanism for each individual attachment point.
