Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the smartphone is mounted on the personal mobility device, then the user can access the smartphone while moving, but the user cannot view the smartphone screen clearly under bright environmental light conditions
Solution Approach 1:
The patent implements dynamic adjustment of the awning structure and holder angle based on real-time illuminance sensor data. The controller automatically modifies the physical configuration of the support structure to create optimal viewing conditions, transforming a static mounting system into an adaptive one that responds to environmental light conditions.
Solution Approach 2:
The system changes physical parameters of the mounting structure (awning extension length, holder angle) based on illuminance levels. When bright light is detected, the awning extends further and the holder adjusts to positions that shield the smartphone screen from direct environmental light, thereby improving screen visibility without sacrificing accessibility.
2Illumination intensity
If the awning structure is extended to block light, then the smartphone becomes more visible, but the structural complexity increases
Solution Approach 1:
The awning structure serves multiple functions: it provides shade for the user, supports the smartphone holder, and acts as a light-blocking element to improve screen visibility. By making the existing structural components multi-functional, the patent avoids adding separate dedicated light-blocking mechanisms, thereby limiting the increase in structural complexity.
Solution Approach 2:
The patent combines the light-blocking function with the existing awning and holder structures rather than adding separate components. The awning extension and holder angle adjustment are integrated into the existing support structure design, merging multiple functions into unified structural elements.
3Illumination intensity
If the holder angle is adjusted to improve viewing, then the smartphone becomes more visible, but the control system complexity increases
Solution Approach 1:
The system uses the illuminance sensor mounted on the personal mobility device itself to detect light conditions and automatically control the holder adjustment. The smartphone's own sensors and processing capabilities are leveraged to determine optimal viewing angles, allowing the system to self-regulate without requiring complex external control systems.
Solution Approach 2:
The system implements a feedback loop where the illuminance sensor continuously monitors environmental light conditions, the controller processes this information, and the holder automatically adjusts its angle in response. This closed-loop control system uses simple sensor-actuator feedback to achieve adaptive positioning without complex control algorithms.
