Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When electronic devices and peripheral devices are coupled with different coupling directions, such as when the coupling direction of a compressible contact structure is perpendicular to the inter-device coupling direction, impacts can occur, leading to defects in the contact structure.
Innovation Solution
A cover device with a bracket and magnets positioned to align perpendicular to each other, allowing for rotation and vertical movement of the terminal part, minimizing impact and improving assembly by using magnetic forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the coupling direction of a compressible contact structure is perpendicular to the inter-device coupling direction, then the assembly direction between electronic device and cover device can be different from terminal coupling direction, but an impact is applied to the contact structure during assembly causing defects
Solution Approach 1:
The bracket is designed to rotate about a rotation axis during assembly, transitioning from a non-contact state to a contact state. This dynamic movement allows the terminal part to approach the contact part along a path perpendicular to the coupling direction, enabling flexible assembly orientation while maintaining contact structure integrity through controlled motion rather than direct impact
Solution Approach 2:
The compressible contact structure is designed with inherent compression capability that absorbs impact during the rotation and coupling process. The compression mechanism acts as a cushioning element that prevents damage to the contact structure when the bracket couples with the housing, allowing perpendicular coupling directions without compromising reliability
2Reliability
If magnets are disposed at various positions to reduce impact on contact structure, then magnetic force can guide assembly and reduce impact, but device complexity increases due to multiple magnets and bracket mechanisms
Solution Approach 1:
The bracket serves multiple functions: it holds the terminal part, provides a rotation axis for controlled movement, positions the first magnet to guide assembly, and enables the terminal part to approach the contact part along a protected path. The first magnet similarly serves multiple roles: guiding assembly orientation and protecting the contact structure. This multi-functionality reduces overall device complexity despite the presence of additional components
Solution Approach 2:
The bracket acts as an intermediary mechanism between the housing and the terminal part. It mediates the coupling process by rotating about the rotation axis and positioning the terminal part to approach the contact part in a controlled manner, reducing direct impact. The magnetic force from the first magnet serves as an intermediary guide that enables precise positioning without mechanical complexity
