Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distributing boards lack a reliable position locking mechanism for electric device units, leading to incomplete connections and potential damage due to over-handling, as they cannot securely lock units in specific positions during maintenance or operation.
Innovation Solution
A distributing board with a position locking device that includes a positioning bracket with concave and convex parts and a locking mechanism, allowing the electric device unit to be locked or unlocked to specific positions, preventing movement and ensuring stable operation, while also providing audible feedback and visual indicators for position recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electric device unit is made detachable for maintenance, then ease of operation is improved, but reliability deteriorates due to potential incomplete connections and over-handling damage
Solution Approach 1:
The locking device is activated before the electric device unit is fully removed from the cabinet, securing it in place during the detachment process. This preliminary locking action prevents accidental displacement and ensures complete disconnection of electrical connections before maintenance begins, thereby maintaining reliability while enabling easy operation
Solution Approach 2:
The locking device acts as an intermediary mechanism between the electric device unit and the cabinet. It provides a controlled transition state during detachment, ensuring that connections are properly managed and secured before the unit is fully removed, thus preventing both incomplete connections and over-handling damage
2Ease of operation
If the electric device unit can be freely moved between positions, then ease of operation is improved, but manufacturing precision deteriorates due to inability to maintain exact positioning
Solution Approach 1:
The locking device provides localized precision at specific positions (service position, test position, disconnect position) while allowing free movement between these positions. Each locking position is precisely defined by corresponding convex and concave structures, ensuring manufacturing precision is maintained at critical points while preserving overall ease of operation
Solution Approach 2:
The positioning bracket and locking device are pre-configured with specific convex and concave structures that define exact positioning points. When the electric device unit is moved to a desired position, the locking mechanism automatically engages with these pre-defined structures, ensuring precise positioning without requiring manual adjustment, thus maintaining manufacturing precision while enabling ease of operation
3Device complexity
If no position locking mechanism is provided, then device complexity is reduced, but reliability deteriorates due to inability to secure units in specific positions
Solution Approach 1:
The locking device operates on a self-service principle where the convex structure on the electric device unit automatically engages with the corresponding concave structure on the positioning bracket when the unit is moved to a correct position. This automatic engagement provides reliable position security without requiring complex external locking mechanisms, thus maintaining relative simplicity while improving reliability
Solution Approach 2:
The locking mechanism is segmented into simple, discrete components: the positioning bracket with convex and concave structures, and the locking device with corresponding engagement features. This segmentation allows the system to achieve reliable position security through simple geometric interlocking rather than complex mechanical systems, balancing device complexity with reliability
