Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric walking aid device requires manual approach or bystander assistance to reach the user, then the device structure remains simple, but the convenience and ease of operation deteriorates
Solution Approach 1:
The electric walking aid device autonomously approaches the user without requiring manual intervention or bystander assistance. The controller automatically controls the driving wheel to move the device toward the user based on detection signals, enabling the device to serve itself in locating and approaching the user.
Solution Approach 2:
The patent replaces manual mechanical approach with an automated detection and control system. Sensors detect the user's presence and the controller automatically adjusts the driving wheel to approach the user, substituting mechanical manual operation with automated sensing and control mechanisms.
2Ease of operation
If the electric walking aid device autonomously approaches the user using detection and navigation systems, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The detection device and control device serve multiple functions: detecting user presence, determining user location, processing navigation information, and controlling device movement. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing complexity while achieving autonomous operation.
Solution Approach 2:
The controller acts as an intermediary between the detection device and the driving wheel. It receives detection signals, processes navigation information, and translates these into control commands for the driving wheel, simplifying the overall system architecture by providing a centralized control interface.
