Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral nursing devices have complex structures for connecting the power output shaft and nursing head, leading to a tedious disassembly and assembly process, which negatively impacts user experience.
Innovation Solution
The device features a clamping member with a connecting arm and clamping protrusion that allows for quick detachment and assembly of the nursing head by elastic deformation, combined with a limiting bracket and quick detachment bracket for stable mounting and sealing, ensuring easy replacement and improved user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex structure is used to connect the power output shaft and nursing head, then the connection stability is improved, but the disassembly and assembly process becomes tedious
Solution Approach 1:
The connection structure is divided into modular components: a limiting bracket with an internal through hole, a quick detachment bracket with an assembly through hole, and a clamping member with connecting and clamping ends. This segmentation allows each component to perform its specific function while enabling quick assembly and disassembly through simple alignment and engagement actions.
Solution Approach 2:
The clamping member acts as an intermediary element between the power output shaft and the nursing head mounting structure. It transmits power while providing a simple clamping mechanism that requires minimal操作步骤 for assembly and disassembly, thus resolving the contradiction between connection stability and ease of operation.
2Adaptability or versatility
If frequent disassembly and assembly is required for nursing head replacement, then the nursing head can be replaced in time, but the user experience deteriorates due to tedious process
Solution Approach 1:
The limiting bracket and quick detachment bracket are pre-configured with aligned through holes and positioning features before use. This preliminary arrangement ensures that when the clamping member is engaged, the nursing head is automatically positioned correctly, enabling quick replacement without complex alignment steps and maintaining high user experience.
3Ease of operation
If a simple connection structure is used, then the disassembly and assembly process is simplified, but the power transmission stability deteriorates
Solution Approach 1:
The clamping member is nested within the quick detachment bracket, with the connecting end attached to the bracket and the clamping end extending through the assembly through hole to engage with the power output shaft. This nested configuration provides a stable power transmission path while maintaining a compact structure that is easy to assemble and disassemble.
