Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high-performance computing devices are used for processing-intensive tasks, then computing capability is improved, but device size and weight increase, restricting user mobility
Solution Approach 1:
The system separates the computing device from the wearable bag, allowing the high-performance computing components to be housed in a portable container that can be carried separately from the body, while the wearable portion only contains essential components like the airflow generator and battery
Solution Approach 2:
A portable bag serves as an intermediary carrier between the user and the high-performance computing device, providing a buffer that allows the heavy computing components to be transported without directly impacting user mobility and comfort
2Weight of moving object
If smaller wearable devices are used to enhance mobility, then user mobility is improved, but processing capability and cooling effectiveness deteriorate
Solution Approach 1:
The wearable system is segmented into two parts: a lightweight wearable bag that can be worn on the body for mobility, and a separate portable container housing the high-performance computing device, allowing each component to be optimized independently for its specific function
Solution Approach 2:
The system transitions from a single integrated wearable device to a distributed system where the computing device resides in a portable container that can be carried alongside the wearable bag, adding a spatial dimension to the wearable architecture
3Power
If high-performance computing devices are used, then processing capability is improved, but heat generation increases, causing user discomfort
Solution Approach 1:
The system captures the waste heat generated by the high-performance computing device and redirects it through the breathable exhaust layer to warm the user's body, converting the harmful heat into a beneficial warming effect that eliminates the need for separate heating elements in cold environments
Solution Approach 2:
The breathable exhaust layer serves as an intermediary between the computing device and the user, managing heat transfer by allowing controlled passage of heated air from the computing device to the user's body, thereby regulating temperature exposure
4Temperature
If active cooling solutions are implemented, then heat management is improved, but device complexity and power consumption increase
Solution Approach 1:
The breathable exhaust layer provides passive thermal management by allowing natural heat dissipation through its porous structure, reducing the need for complex active cooling mechanisms and lowering overall system complexity
Solution Approach 2:
The breathable exhaust layer serves multiple functions simultaneously: it allows heat dissipation, provides structural support, and enables controlled airflow, eliminating the need for separate dedicated cooling components and simplifying the overall system architecture

Implementation Method 1
an airflow generator arranged inside the inner chamber to produce an airflow to cool the computing device and to direct a resulting heated airflow to flow through pores of the liquid resistant and breathable layer to an environment outside the outer case
Implementation Method 2
a thermally reflective layer arranged along a side of the outer case adjacent the user when the outer case is worn by the user, the thermally reflective layer being configured to reflect heat from the computing device away from the user
Implementation Method 3
a liquid resistant and breathable layer including pores through which a heated airflow can pass from inside the inner chamber to an environment outside the outer case

AI summary
In some examples, a wearable system includes an outer case defining an inner chamber and comprising a portion including a liquid resistant and breathable layer. The wearable system further includes a computing device in the inner chamber, and an airflow generator to produce an airflow to cool the computing device and to direct a resulting heated airflow to flow through pores of the liquid resistant and breathable layer to an environment outside the outer case.
