Multi-Hinge Latch System for Secure Base Station Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld device and base station designs face issues with secure connections in various orientations, inadequate retention against vibrations and impacts, and excessive wear due to sliding friction in electrical contacts, leading to performance degradation in charging and data transfer.
Innovation Solution
The implementation of a multi-point latch system with adjustable latching configurations and a multi-hinge electrical connection system that provides rolling friction engagement, allowing secure retention and reduced wear through adjustable latching and rolling contact mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional single latch system is used, then the device can be secured in one orientation, but it cannot provide secure retention in multiple orientations or against vibrations and impacts
Solution Approach 1:
The latch system is divided into multiple independent latch members (first latch member, second latch member, third latch member) that can be selectively engaged. Each latch member targets a different location on the handheld device, providing distributed secure retention across multiple orientations and against various forces including vibrations and impacts.
Solution Approach 2:
The latch system incorporates a control body that can be moved between multiple control orientations to selectively engage different combinations of latch members. This dynamic configuration allows the system to adapt to different operational requirements, providing secure retention in various orientations while maintaining reliability.
2Reliability
If sliding friction electrical contacts are used, then electrical connection is achieved, but excessive wear occurs leading to performance degradation
Solution Approach 1:
The electrical connection system replaces sliding friction contacts with rolling friction engagement. The first hinge member and second hinge member enable rolling motion between electrical contacts, significantly reducing wear and extending the lifespan of the electrical connection while maintaining reliable connectivity for charging and data transfer.
3Adaptability or versatility
If a multi-point latch system with adjustable configurations is implemented, then secure retention in multiple orientations is achieved, but device complexity increases
Solution Approach 1:
Multiple latch members and their control mechanisms are integrated into a single unified control body. The control body incorporates multiple control profiles that interact with different latch members, allowing a single component to manage the complexity of engaging and disengaging multiple latches while providing secure retention in various orientations.
Solution Approach 2:
The control body serves multiple functions: it selectively engages different latch members, provides user interaction for mode selection, and coordinates the operation of multiple latches through integrated control profiles. This multi-functionality reduces the need for separate control mechanisms for each latch member.

AI summary
A base station or handheld device can be equipped with a latch system or a multi-hinge arrangement for electrical contacts. The latch system can be adjustable between different latching configurations in which the base station and handheld device are retained together by different degrees. The multi-hinge arrangement can provide rotation about multiple axes to provide rolling contact between electrical contacts of the base station and the handheld device.
