An electronic apparatus design featuring a base with a rotating component and elastic connection portions that engage via a magnetic attraction force, ensuring secure positioning and eliminating gaps caused by tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixing structure (e.g., hook) is used to fix the portable electronic apparatus, then the apparatus can be secured on the docking base, but manufacturing and assembling tolerances cause gaps between the apparatus and base, resulting in wobbling
Solution Approach 1:
The patent employs an elastic component that changes its physical state from compressed to relaxed, dynamically adjusting the connection between the rotating component and electronic device. This parameter change allows the system to accommodate manufacturing tolerances while maintaining stable positioning, resolving the contradiction between reliability and manufacturing precision.
Solution Approach 2:
The rotating component transitions from a static fixing structure to a dynamic element that can rotate and adjust its position. This dynamic mechanism absorbs dimensional variations through rotational movement, enabling the system to maintain stability despite manufacturing tolerances in the connection between base and electronic device.
2Ease of manufacture
If a rigid fixing structure is used, then assembly is simple, but the structure cannot accommodate dimensional variations, causing gaps and instability
Solution Approach 1:
The fixing structure is divided into multiple functional segments: the rotating component, elastic component, and positioning portion. This segmentation allows each element to perform its specific function - the rotating component provides rotational adjustment, the elastic component provides force, and the positioning portion provides precise engagement - collectively achieving both ease of manufacture and reliable stability.
Solution Approach 2:
The elastic component acts as an intermediary between the rotating component and the electronic device, transmitting force while accommodating dimensional variations. This mediator element absorbs the shock of manufacturing tolerances, allowing the simple rotating mechanism to achieve reliable, stable connection without complex adjustment procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents wobbling by firmly securing the electronic device on the base, enhancing user comfort and operational stability.
Implementation Method 1
the elastic component pushes the driven portion, such that the positioning portion is engaged into the positioning trench
Implementation Method 2
a magnetic attraction force between the another magnetic component and the connecting portion drives the rotating component to rotate

AI summary
An electronic apparatus includes a base and an electronic device. The base includes a first main body and at least one first connection portion. The first connection portion includes a rotating component, and the rotating component is pivoted to the first main body and has a driven portion and a positioning portion. The electronic device includes a second main body and at least one second connection portion. The second connection portion includes an elastic component and a positioning trench. The elastic component is connected to the second main body, and the positioning trench is formed on the second main body. When the base supports the electronic device so that the first connection portion is aligned to the second connection portion, the elastic component pushes the driven portion such that the positioning portion is engaged into the positioning trench.
