Adaptive Cable Connection Device with Dynamic Holding Force Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable disconnection and connector breakage issues arise due to the inability of existing cable connection mechanisms to adaptively manage the holding force based on environmental conditions, particularly in scenarios like in-flight entertainment systems where passengers frequently interact with and disconnect cables.
Innovation Solution
A connection device equipped with a holding mechanism that adjusts its force based on environment information, such as seating and playback states, using a CPU to control the holding mechanism to maintain a secure connection without excessive force, thereby reducing the risk of disconnection or breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable connection mechanism uses a fixed holding force to maintain connection stability, then the connection reliability is improved, but the risk of connector breakage increases when disconnection is needed
Solution Approach 1:
The holding mechanism transitions from a static fixed holding force to a dynamic adjustable holding force that can be changed based on operational conditions. The controller adjusts the holding force between a first level (during use) and a second level (lower, during disconnection), allowing the system to adapt between maintaining stable connection and enabling safe disconnection, thereby resolving the contradiction between connection reliability and connector durability.
Solution Approach 2:
The system changes the holding force parameter from a constant value to a variable value with at least two distinct levels. By controlling the holding force to switch between a first holding force (providing strong connection stability) and a second holding force (providing weaker force for safe disconnection), the system resolves the contradiction between maintaining reliable connection and preventing connector breakage during disconnection operations.
2Reliability
If a cable connection mechanism uses strong holding force to prevent disconnection, then connection stability is improved, but ease of operation deteriorates when disconnection is required
Solution Approach 1:
The holding mechanism dynamically adjusts its holding force based on operational state. During active use, a first holding force maintains stable connection. When disconnection is required, the controller switches to a second holding force that is weaker, making it easier to remove the cable while maintaining connection stability during operation.
Solution Approach 2:
The holding force is applied periodically or intermittently rather than continuously at maximum strength. The controller switches between a first holding force (during connection phase) and a second holding force (during disconnection phase), creating a periodic action pattern that ensures stable connection when needed while facilitating easy disconnection when required.
3Strength
If a cable connection mechanism uses adaptive holding force adjustment based on environment information, then connector durability is improved, but device complexity increases
Solution Approach 1:
The controller receives environment information as feedback about the operational context and uses this feedback to automatically adjust the holding force of the holding mechanism. This feedback-based control enables the system to adaptively switch between first and second holding forces based on actual conditions, improving connector durability while keeping the control logic relatively simple through automated decision-making.
Solution Approach 2:
The holding mechanism automatically adjusts its own holding force based on environment information received by the controller, without requiring manual intervention. The system serves itself by autonomously switching between different holding force levels according to operational conditions, reducing the need for complex manual control mechanisms while improving connector durability.
