Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users bring portable electronic devices to the location of interest to obtain position information, then positioning accuracy is improved, but accessibility and contact restraint issues prevent users from reaching certain locations
Solution Approach 1:
The patent replaces the mechanical approach of physically transporting the device to the target location with a non-contact measurement system. The range finding module uses optical or electromagnetic waves to measure distance, the position identifying module uses sensors to detect azimuth angles, and the inertia sensing module uses accelerometers to detect device orientation, collectively enabling remote positioning without mechanical transport to the target site.
Solution Approach 2:
The patent introduces multiple intermediary modules that mediate between the user and the target object. The range finding module acts as an intermediary to measure distance without contact, the position identifying module serves as an intermediary to sense relative position, and the processing unit acts as an intermediary to calculate final coordinates by integrating data from all modules, thereby enabling indirect positioning when direct access is restricted.
2Ease of operation
If non-contact positioning is implemented using multiple modules (range finding, position identifying, inertia sensing), then accessibility is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple independent positioning modules (range finding module, position identifying module, inertia sensing module, and positioning unit) into a single integrated portable electronic device. The processing unit coordinates all modules and integrates their outputs to calculate target coordinates, combining several functions into one unified system that maintains accessibility while managing complexity through integrated design.
Solution Approach 2:
The portable electronic device is designed with multi-functionality, serving both as a general-purpose computing device and as a specialized positioning instrument. The same device can perform everyday tasks while also executing non-contact positioning operations by activating the specific modules needed for distance measurement, angle sensing, and coordinate calculation, thereby reducing the need for separate specialized equipment.
3Measurement precision
If multiple sensing modules are used to detect distance, azimuth angle, and movement, then positioning precision is improved, but the number of components and processing requirements increase
Solution Approach 1:
The patent segments the positioning function into three distinct modules, each responsible for a specific measurement task: the range finding module for distance detection, the position identifying module for azimuth angle sensing, and the inertia sensing module for movement and tilt detection. This segmentation allows each module to be optimized for its specific function while the processing unit integrates their outputs, improving overall precision through specialized measurement components.
