Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional headphones are shared between multiple people, then audio sharing is enabled, but hygiene is compromised and range of motion is limited
Solution Approach 1:
The audio output is segmented into multiple independent headphone jack outputs, allowing each user to have their own dedicated headphone connection rather than sharing a single jack. This segmentation enables simultaneous audio sharing while maintaining hygiene by eliminating direct contact between users' headphones.
Solution Approach 2:
The case acts as an intermediary device between the electronic device and multiple users' headphones. It contains the auxiliary splitter circuitry and multiple headphone jack outputs, serving as a mediating component that distributes audio signals to multiple users without requiring them to share the original device's single headphone jack.
2Adaptability or versatility
If multiple proprietary charging ports are supported, then charging compatibility is improved, but device complexity increases
Solution Approach 1:
Multiple charging adapter functions are merged into a single integrated case structure. The case houses multiple charging ports (Lightning, Micro USB, USB-C) and associated circuitry within one unified device, eliminating the need for users to carry separate charging adapters for different device types.
Solution Approach 2:
The case is designed with universal charging capability, incorporating multiple types of charging ports and adapters to work with various electronic devices. This multi-functional design allows a single case to serve multiple charging purposes across different device ecosystems.
3Reliability
If charging cables are connected internally, then charging function is enabled, but mechanical wear increases and accessibility is reduced
Solution Approach 1:
The charging cable connection system is made dynamic by allowing the cable to be externally accessible rather than permanently fixed internally. The cable can be connected and disconnected from the outside of the case, enabling flexible access while maintaining internal organization when connected.
Solution Approach 2:
The case serves as an intermediary between the charging cable and the electronic device. The cable connects to the case from the outside, and the case's internal circuitry mediates the connection to the device, protecting internal components while maintaining external accessibility.
