Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection systems require significant pressure to maintain contact quality, which is not compatible with the desired sliding mechanism for connecting and disconnecting electrical devices from a power source and control equipment.
Innovation Solution
A device with a support and second part attachment mechanism using friction contact between poles, secured by locks, allowing contact maintenance without slippage and enabling secure connection even when friction is insufficient, and utilizing a flexible portion that collapses to separate the support from the drawer, ensuring transition between operating zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sliding contacts are used to connect and disconnect electrical devices, then the connection mechanism becomes simple and easy to operate, but significant pressure is required to maintain contact quality which is not compatible with the sliding mechanism
Solution Approach 1:
The connection system is divided into two independent lines: a first connection line for power supply with male poles fixed to the movable drawer, and a second connection line for control equipment with male poles fixed to a support that can be independently attached to the drawer face. This segmentation allows each line to have optimized contact mechanisms without compromising the other.
Solution Approach 2:
A support structure acts as an intermediary between the drawer and the control equipment connection poles. This support can be selectively attached to the drawer face using friction or locks, enabling the control connection to be maintained or established independently of the power connection, thus resolving the conflict between sliding operation and contact pressure requirements.
2Reliability
If male poles are made longer to ensure contact in intermediate positions, then connection reliability improves, but the device complexity increases
Solution Approach 1:
The support carrying the control equipment male poles is made dynamically attachable and detachable from the drawer face. This dynamic configuration allows the support to be positioned at different distances from the drawer face depending on the operating zone, enabling reliable contact without requiring multiple fixed pole lengths. The support can be attached when needed and detached when transitioning between zones.
3Device complexity
If friction contact is used to maintain connection, then the mechanism becomes simpler without locks, but friction may be insufficient to ensure reliable connection
Solution Approach 1:
The support is pre-configured with attachment means (friction contact and/or locks) that can be engaged before the connection is needed. This preliminary attachment ensures that when the support carries the control equipment male poles toward the female poles, reliable contact is guaranteed. The attachment means are engaged in advance, eliminating the need to rely solely on friction during the connection process.
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
Ensures reliable connection and disconnection of electrical devices by maintaining contact without slippage and securing the support, independent of friction levels, allowing for efficient operation across different operating zones.
Implementation Method 1
the flexible portion collapses under pressure from the end to separate the support from the first part
Implementation Method 2
the attachment between the support and the second part is ensured by friction in contact between the at least one first pole belonging to the second line and the at least one second pole belonging to the second line
