Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable is used to connect an external device to a glasses-type electronic device, then data and power transfer are enabled, but cable interference and inconvenience occur
Solution Approach 1:
The frame is divided into multiple components including a front frame, side frames, and a temple piece that can be selectively assembled. The port is specifically positioned at the connection between the side frame and front frame, allowing the cable to route through the temple piece without interfering with the user's face or ears.
Solution Approach 2:
The port is positioned in three-dimensional space at the outer side of the connection point between the side frame and front frame, utilizing the spatial dimension to route the cable away from the user's head and face area, thereby eliminating cable interference while maintaining connectivity.
2Weight of moving object
If a head unit is coupled to a glasses-type electronic device using a band, then portability is improved, but the existing frame structure causes inconvenience in coupling and fixing
Solution Approach 1:
The frame is segmented into a front frame, side frames, and a temple piece that can be selectively assembled. This segmentation allows the temple piece to serve as a dedicated mounting structure for the head unit, simplifying the coupling process while maintaining the lightweight advantages of glasses-type devices.
Solution Approach 2:
The temple piece serves multiple functions: it connects the side frame to the front frame structurally, provides a mounting interface for the head unit through the connection unit, and enables selective coupling of the head unit when needed. This multi-functionality resolves the inconvenience of the existing frame structure.
3Reliability
If all necessary components such as processor and sensor are mounted in a glasses-type electronic device, then performance is improved, but weight and volume increase
Solution Approach 1:
The electronic device is divided into a lightweight glasses-type main body and a separate head unit containing heavier components. The main body includes only essential components for basic functionality, while the head unit houses the processor, sensor, and battery, which can be selectively coupled when high performance is needed.
Solution Approach 2:
The configuration of the device is dynamic rather than fixed. The head unit can be selectively coupled to the glasses-type main body when high performance is required, and removed when portability is prioritized. This dynamic reconfiguration allows the system to adapt between performance and portability modes.
4Adaptability or versatility
If a head unit is selectively coupled to a glasses-type electronic device, then both portability and high-performance configurations are enabled, but a separate fixing structure is required
Solution Approach 1:
The fixing structure is merged into the frame itself through the connection unit that integrates the temple piece with the side frame and front frame. This eliminates the need for separate fixing structures, as the frame's own components serve as the mounting mechanism for the head unit.
Solution Approach 2:
The temple piece and connection unit serve multiple functions: they provide the structural connection between frame components, enable selective coupling of the head unit, and eliminate the need for separate fixing structures. This multi-functionality reduces device complexity while maintaining adaptability.
