Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If split-type glasses set up the battery and glasses main body separately to reduce weight, then the weight of the glasses is reduced and battery life is increased, but the thick power cable makes the ear difficult to bear and the transmission line interferes with user activities
Solution Approach 1:
The system is divided into three main segments: lightweight smart glasses body, separate wearable battery pack, and magnetic connection device. This segmentation allows the heavy battery to be worn on the chest while the glasses remain lightweight on the ear, solving the weight distribution problem.
Solution Approach 2:
A magnetic connection device acts as an intermediary between the glasses and battery pack. It includes a magnetic attractor in the glasses and a magnetic connector in the battery pack, enabling automatic connection and disconnection without manual cable handling, thus improving ease of operation.
2Power
If split-type glasses use a thick power cable for power transmission, then sufficient power can be supplied, but the long and thick transmission line hanging around the ear affects user image and comfort
Solution Approach 1:
The thick power cable is extracted from the visible area around the ear and relocated to the chest area where the battery pack is worn. Only a thin connection line remains visible near the ear, dramatically improving aesthetics and comfort while maintaining sufficient power transmission capability through the magnetic connection.
Solution Approach 2:
The power transmission path is moved from the horizontal dimension (around the ear) to the vertical dimension (from chest to ear). The battery pack is positioned on the chest and connects upward to the glasses, hiding the thick cable in an aesthetically acceptable location.
3Adaptability or versatility
If the transmission line is made longer to allow head movements, then user mobility is improved, but the dragging and pulling restraints of the transmission line make it inconvenient to take off
Solution Approach 1:
The magnetic connection device serves as an intermediary that enables quick connection and disconnection. The magnetic attractor and connector automatically engage when brought close together and easily separate with a simple pull, reducing the time and effort required to put on and take off the glasses.
Solution Approach 2:
The magnetic connection is prepared in advance by positioning the magnetic attractor in the glasses and magnetic connector in the battery pack. When the user brings them close, the magnetic force automatically guides and secures the connection, eliminating the need for manual plugging and reducing setup time.
