Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components (viewing frames, securement arms) are made interchangeable to enhance adaptability, then component versatility improves, but electrical connection reliability deteriorates due to degradation from repeated connections and disconnections
Solution Approach 1:
The device is divided into separable modules (display frame, securement arms, batteries, projectors) that can be independently swapped. The electrical bridge acts as a separate intermediary component that maintains connections between these segments, allowing them to be exchanged without compromising the electrical pathways.
Solution Approach 2:
An electrical bridge is introduced as an intermediary component between the display frame and securement arms. This bridge maintains continuous electrical connections even when components are swapped, preventing direct connection degradation by serving as a stable intermediate pathway for power and data transmission.
2Adaptability or versatility
If electrical connections are made between multiple components to enable functionality, then device capability improves, but design and manufacturing complexity increases
Solution Approach 1:
The electrical bridge serves multiple functions simultaneously: it provides electrical connections, maintains mechanical stability, and enables component interchangeability. This multi-functionality reduces the need for separate dedicated components for each function, thereby reducing overall system complexity despite having multiple interconnected components.

AI summary
A wearable display device can include a display including a display frame including a first lateral side and a second lateral side. A first securement arm removably coupled to the first lateral side at a proximal end of the first securement arm. The first securement arm can include a first electronic component and a projector configured to direct light displayed at the display. A second securement arm removably coupled to the second lateral side at a proximal end of the second securement arm. The second securement arm can include a second electronic component. An electronic connector can be configured to extend between the proximal ends of the first and second securement arms and electrically couple the first electronic device to the second electronic device. The electronic conductor can also be configured to couple to the display frame and conform to a shape of the display frame.
