Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single output module is used in the controller device, then the device complexity is reduced, but the tracking precision of the controller device location and movement deteriorates
Solution Approach 1:
The controller device is divided into multiple surfaces (first surface, second surface, third surface, fourth surface, fifth surface) with output modules distributed across these segments. This segmentation allows the system to track the controller from multiple spatial perspectives, improving tracking precision while keeping each individual output module simple.
Solution Approach 2:
Output modules are arranged not only on the front surface but also extended to side surfaces (second, third, fourth surfaces) and inner surfaces (fifth surface). This multi-dimensional arrangement enables the wearable device to receive signals from various angles, enhancing spatial tracking accuracy without significantly increasing device complexity.
2Measurement precision
If multiple output modules are arranged on multiple surfaces of the controller device, then the tracking precision is improved, but the manufacturing complexity increases
Solution Approach 1:
The controller housing is segmented into multiple surfaces, each capable of independently accommodating output modules. This segmentation allows for modular manufacturing where each surface can be processed and assembled separately, reducing the overall manufacturing precision requirements compared to a monolithic structure.
Solution Approach 2:
The multiple surfaces of the controller housing serve dual purposes: they provide structural form factors and simultaneously function as mounting platforms for output modules. This multi-functionality reduces the need for additional specialized components, simplifying the manufacturing process.
3Reliability
If the controller device is held in the user's hand and moves according to user movement, then the ease of operation is maintained, but the tracking reliability deteriorates due to inaccurate location determination
Solution Approach 1:
By arranging output modules on multiple surfaces including side and inner surfaces, the system can detect controller position and orientation from multiple angular perspectives. This multi-dimensional signal reception maintains tracking reliability even when the controller is held in various hand positions, without restricting user operation flexibility.
Solution Approach 2:
The wearable electronic device receives signals from multiple output modules and uses this feedback to continuously calculate and update the controller's location and movement. This real-time feedback mechanism maintains tracking reliability while allowing the controller to move freely with user hand movements.
