Solution Overview
Problem
Conventional vehicle seats lack flexibility in movement and configuration, making it difficult to adjust their direction or position, and storage devices within vehicles often require improved mobility and secure fixation to enhance user convenience and safety.
Innovation Solution
A moving device with a rail unit embedded in the vehicle floor, a storage unit that moves along this rail, and a magnetic unit with opposite polarities on both sides to enhance adherence, along with a fixing unit for secure attachment, ensuring stability and ease of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a storage device is made movable along a rail unit, then the degree of freedom and flexibility of the storage space is improved, but the reliability and stability of the storage device during movement becomes problematic
Solution Approach 1:
The magnetic unit's magnetic force is dynamically adjusted based on the operational state: during movement, the magnetic force is weakened to allow smooth sliding along the rail unit; when stopping is detected, the magnetic force is strengthened to securely hold the storage device in place. This dynamic adjustment resolves the contradiction between movement flexibility and stability.
Solution Approach 2:
The magnetic force parameter is changed between two states: a weaker state during movement that reduces friction and allows easy sliding, and a stronger state during stopping that provides secure fixation. This parameter change enables the system to achieve both mobility and stability at different operational phases.
2Ease of operation
If a magnetic unit is used to enable movement along the rail unit, then the ease of operation is improved, but the harmful factors such as unintended movement or detachment increases
Solution Approach 1:
The system incorporates a sensor that detects whether the storage device is in motion or stationary, providing feedback to the control unit. Based on this feedback, the control unit adjusts the magnetic force accordingly: reducing it during movement to ease operation, and increasing it when stationary to prevent unintended detachment, thus eliminating harmful factors.
Solution Approach 2:
The traditional mechanical locking mechanism is replaced with a magnetic field-based system. The magnetic unit provides contactless adherence to the rail unit, eliminating mechanical wear and complex locking structures while enabling easy movement through simple magnetic force modulation.
3Reliability
If the magnetic force is strengthened to prevent detachment, then the reliability is improved, but the ease of movement deteriorates due to increased friction
Solution Approach 1:
The magnetic force is dynamically controlled rather than maintained at a constant high level. During movement, the magnetic force is reduced to minimize friction and enable easy sliding. When the storage device needs to be held in place, the magnetic force is increased to prevent detachment. This dynamic control resolves the contradiction between strong adherence and easy movement.
4Stability of the object's composition
If a fixing unit is added to secure the storage device, then the stability is improved, but the device complexity increases
Solution Approach 1:
The complex mechanical fixing unit with moving parts and locking mechanisms is replaced with a simplified magnetic fixing system. The magnetic unit, controlled by magnetic force modulation, provides stable fixation without requiring complex mechanical structures, thus improving stability while reducing device complexity.
