Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If head-mounted devices include multiple components and functions, then functionality and versatility are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The head-mounted device is divided into separate modular components including a frame module, arm modules, and additional modules that can be independently manufactured and assembled. Each module contains specific functional components that can be selected and combined based on user needs, allowing versatility without requiring a single complex integrated device.
Solution Approach 2:
The frame module and arm modules are designed with universal attachment mechanisms that can accommodate various combinations of modules. The same frame module can work with different arm modules and additional modules, creating a universal platform that provides multiple functions through module selection rather than integrating all functions into a single complex unit.
2Adaptability or versatility
If head-mounted devices include multiple components and functions, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the device into separate modules, each module can be manufactured independently using optimized processes for that specific component. This allows for economies of scale in module production and reduces the complexity and cost of manufacturing a single integrated device with all possible functions.
Solution Approach 2:
The modular design allows individual modules to be replaced, upgraded, or removed based on user needs without replacing the entire device. This extends the lifecycle of the base frame module and allows users to invest only in the specific functional modules they require, reducing overall manufacturing costs.
3Reliability
If modules are securely connected, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The attachment mechanism merges mechanical connection features with electrical connection features into a single integrated interface. The arm module attachment elements include both mechanical engagement structures for secure physical connection and electrical contact elements for data and power transmission, achieving reliable multi-functional connection without increasing overall assembly complexity.

AI summary
Head-mounted devices can be formed as a modular system that provides a variety of different components and functions to achieve the results that are desired by a user. The modular configurations allow a user to easily customize a head-mounted device with one or more arm modules to provide features that integrate with other operations of the frame module of the head-mounted device. The arm modules can be easily exchanged with each other to provide different components and functions at different times. Accordingly, a frame module of a head-mounted device need not include permanent components that provide every function that will later be desired by the user. Instead, the head-mounted device can have expanded and customizable capabilities by the use of one or more arm modules.
