Rotatable Plug With Fixable Converter And Hook Locks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotatable plugs have weak mechanical structures, leading to damage, unreliability, and safety concerns due to the lack of a fixing mechanism between the converters and the plug, which affects the durability and reliability of electric power connectors in consumer electronics.
Innovation Solution
A rotatable plug with a fixable converter design that includes a lower case with through holes and plug receiving slots, a locking member with hook locks, a fixing member with clamping fixtures, and a converter with hooks that pass through openings in the lower case and are locked by the hook locks, providing a secure attachment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional foldable or rotatable fixtures are used without a fixing mechanism, then the device complexity is reduced and ease of manufacture is improved, but the mechanical structure becomes weak causing damage, unreliability, and safety concerns
Solution Approach 1:
The fixing mechanism is divided into separate functional components: a locking member with hook locks on the lower case, a fixing member with clamping fixtures, and hooks on the converter. This segmentation allows each component to perform its specific function while maintaining overall simplicity and manufacturability.
Solution Approach 2:
The fixing mechanism is designed to be self-securing through the interaction of hooks passing through openings and being locked by hook locks, with clamping fixtures that automatically engage. The spring provides automatic tensioning, eliminating the need for additional fixing operations or complex assembly steps.
2Reliability
If a fixing mechanism with locking member and clamping fixtures is added to the rotatable plug, then the durability and reliability are improved, but the device complexity increases
Solution Approach 1:
Multiple fixing functions are merged into a compact integrated mechanism: the locking member combines hook locks with the lower case, the fixing member integrates clamping fixtures, and the spring provides both tensioning and positioning. This merging reduces the number of separate components and simplifies the overall structure.
Solution Approach 2:
The locking member serves multiple functions: it provides structural support as part of the lower case, contains the hook locks for securing the converter, and houses the spring mechanism. The fixing member simultaneously provides clamping force and positional alignment through its clamping fixtures.
3Ease of operation
If the converter is attached without a fixing mechanism, then the ease of operation is improved and the device is easier to assemble, but the converter falls off during use causing safety issues
Solution Approach 1:
The hook locks act as an intermediary between the converter hooks and the lower case, providing a secure mechanical connection. The spring serves as an intermediary that maintains continuous tension on the locking mechanism, ensuring the converter remains firmly attached during operation.
4Duration of action of stationary object
If a robust fixing mechanism with multiple components is implemented, then the durability for long-term use is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The spring's elastic properties are utilized to provide dynamic tensioning and compensation for manufacturing tolerances. By changing the physical state from rigid to elastic, the mechanism accommodates variations in component dimensions while maintaining secure attachment over extended periods.
