Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If securement arms are made fixed and rigid to ensure reliable securing, then reliability improves, but adaptability to different head sizes and shapes deteriorates
Solution Approach 1:
The securement arm is transformed from a fixed rigid structure to a dynamic adjustable structure. The arm includes a telescopic portion with multiple extendable segments that can be adjusted to different lengths and positions, allowing the same device to adapt to various head sizes and shapes while maintaining reliable securing through the adjustable firm contact.
Solution Approach 2:
The physical parameters of the securement arm (length, position, angle) are made changeable through the telescopic mechanism. The arm can be extended or retracted to different positions along the frame, and the contact point with the head can be adjusted, enabling the device to accommodate different anatomical variations while ensuring reliable securing at each adjusted position.
2Adaptability or versatility
If device components are arranged to accommodate various anatomical features, then adaptability improves, but device complexity increases
Solution Approach 1:
The securement arm is segmented into multiple extendable portions that can be independently adjusted. This segmentation allows each segment to be positioned to match the user's specific anatomical features without requiring complete redesign of the entire arm structure, thereby achieving adaptability with controlled complexity through modular adjustment.
Solution Approach 2:
The telescopic securement arm serves multiple functions: it can adjust to different head sizes, different head shapes, and different securing positions. This multi-functionality is achieved through a single integrated telescopic mechanism rather than requiring separate adjustment mechanisms for each anatomical variation, thus improving adaptability while limiting the increase in overall device complexity.
3Adaptability or versatility
If securement arms are made adjustable to fit various head sizes, then adaptability improves, but device complexity increases
Solution Approach 1:
The securement arm incorporates a dynamic telescopic mechanism that allows length and position adjustment through a unified structural design. The extendable portions can be adjusted along the frame in a coordinated manner, providing fit customization without requiring multiple independent adjustment mechanisms, thus achieving adaptability with relatively controlled complexity.
4Ease of operation
If device is designed to be compact and aesthetic, then ease of operation in public settings improves, but reliability of securing may deteriorate
Solution Approach 1:
The securement arm transitions from a compact stored position to an extended securing position. When not in use, the telescopic portions remain retracted, maintaining a compact and aesthetically pleasing profile suitable for public settings. When securing is needed, the arm extends to the appropriate length and position, ensuring reliable contact with the head. This dynamic transformation allows the device to satisfy both aesthetic requirements and securing reliability requirements at different operational states.

AI summary
A head mountable electronic device can include a display frame, a display window secured to the display frame, and a fixed portion extending distally from the display frame, the fixed portion including a proximal end adjacent the display window, a distal end opposite the proximal end, and an electronic component. The head mountable electronic device can also include a securement arm, the securement arm including a hinge segment rotatably coupling the securement arm with the proximal end of the fixed portion and an elongated member extending distally from the hinge.
