Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional charging methods requiring precise alignment are used, then secure placement is achieved, but charging time increases and convenience deteriorates
Solution Approach 1:
The patent replaces the traditional mechanical alignment-based charging system with a magnetic field-based charging system. The magnetic charging portion generates a magnetic field that automatically guides and secures the metal detector to the charging device, eliminating the need for manual precise alignment while maintaining secure placement. This substitution of mechanical alignment with magnetic attraction directly resolves the contradiction by improving ease of operation without increasing charging time.
2Productivity
If magnetic suction is used to fix the metal detector, then pickup and placement speed improves, but secure fixation must be maintained
Solution Approach 1:
The patent employs parameter changes by utilizing variable magnetic field strength to achieve both fast pickup/placement and secure fixation. The magnetic charging portion can adjust its magnetic field intensity to provide strong attraction for rapid securing while allowing easy release when needed. This dynamic parameter adjustment resolves the contradiction between charging speed and fixation security by optimizing the magnetic force level for different operational phases.
3Manufacturing precision
If the charging placement surface is tilted, then alignment is improved, but structural complexity increases
Solution Approach 1:
The patent applies the counterweight principle by designing the magnetic charging portion to compensate for the tilted placement surface. The magnetic force acts as a counterbalancing force that ensures the metal detector aligns properly on the tilted surface, with the magnetic attraction counteracting the gravitational component that would cause misalignment. This approach achieves precise alignment without requiring complex mechanical adjustment mechanisms, thereby resolving the contradiction between alignment precision and structural complexity.

Data Source
AI summary
The application disclosed a charging device and security inspection device. The body of the charging device is formed into a charging placing surface, and the first magnetic part is arranged on the side of the charging placing surface facing the inside of the charging device. The first magnetic suction portion is used to fix the metal detector onto the charging placement surface. When the metal detector needs to be picked up from the charging device, the metal detector can be picked up by grasping the handle of the metal detector overcoming the magnetic force of the first magnetic suction portion. Compared with traditional charging devices, there is no need to first take the metal detector's detection part and then convert the holding position.
