Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injection member assemblies for bidets suffer from jittering and slipping issues during the extension and retraction of the injection member, which affects their stability and operational smoothness.
Innovation Solution
A compact and durable injection member assembly is achieved by immovably fixing the driving assembly to the bracket assembly, utilizing a motor-driven gear system with a dentate guiding surface to minimize jittering and slipping, allowing the injection member to extend and retract smoothly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driving assembly is provided to realize extension and retraction of the injection member, then the functionality is improved, but jittering and slipping occur during operation
Solution Approach 1:
The guiding surface is designed with a curved shape that matches the arcuate path of the injection member's movement. This curved guiding surface ensures continuous contact and proper engagement between the driving gear and the guiding surface throughout the extension and retraction cycle, eliminating jittering and slipping while maintaining smooth operation.
Solution Approach 2:
The patent introduces a guiding surface as an intermediary element between the driving assembly and the bracket assembly. This guiding surface acts as a mediator that translates the rotational motion of the driving gear into smooth linear motion of the injection member, ensuring stable operation without direct rigid connection that would cause jittering.
2Reliability
If the driving assembly is coupled with the incurved segment of the bracket assembly, then jittering is minimized, but the device complexity increases
Solution Approach 1:
The driving assembly is integrated with the bracket assembly by coupling the driving gear directly to the incurved segment of the bracket. This merging of components eliminates the need for separate mounting structures and reduces overall device complexity while maintaining the jitter-reducing benefits of the curved engagement surface.
Solution Approach 2:
The incurved segment of the bracket assembly provides a curved engagement surface that naturally guides the driving gear's motion. This curved geometry simplifies the overall structure by eliminating the need for additional guiding mechanisms while effectively minimizing jittering through proper force distribution.
