Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the robot cleaner relies on basic return induction signal transmission, then the charging device can guide the robot cleaner to return, but the docking accuracy is insufficient and lateral movement occurs during docking
Solution Approach 1:
An induction signal guide member is introduced as an intermediary component between the induction signal generating unit and the robot cleaner. This guide member shapes and directs the return induction signal to form a linear signal path, thereby improving docking accuracy without requiring complex adjustments to the robot cleaner or charging device主体结构
Solution Approach 2:
The induction signal guide member extends in the width direction (lateral dimension) to physically constrain and direct the induction signal laterally. This dimensional approach converts the signal transmission from a point-source radial pattern to a directed linear pattern, reducing lateral movement during docking
2Force
If the power supply terminal and charging terminal are connected without additional support structures, then the docking process is simple, but the contact force between terminals is insufficient for effective charging
Solution Approach 1:
The terminal supporting member is designed with elastic properties, allowing it to dynamically adjust and maintain optimal contact force between the power supply terminal and charging terminal. The elastic deformation of the supporting member provides continuous pressure to ensure reliable electrical contact during docking
Solution Approach 2:
A terminal supporting member is introduced as an intermediary between the power supply terminal and the charging terminal. This supporting member acts as a mechanical mediator that transmits and maintains the necessary contact force, ensuring effective charging while isolating the terminal connection from direct rigid contact
