Solution Overview

Problem

Conventional injection assemblies for bidets often suffer from jittering or slipping issues when the injection member extends and retracts.

Innovation Solution

The injection member assembly includes a driving assembly and a bracket assembly with a coupling member that minimizes slipping and jittering by using a guiding surface, such as an incurved rack or slot, allowing the injection member to move smoothly and be fixedly connected to either the driving assembly or the bracket, which can be immovably fixed for enhanced stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional injection assemblies are used, then the structure is simple, but the injection member experiences jittering or slipping during extension and retraction

Engineering Contradiction:

Improvestability during extension and retractionVSAvoidassembly structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

A coupling member is introduced as an intermediary element between the driving assembly and the injection member. This coupling member includes a coupling surface that engages with a guiding surface on the bracket assembly, serving as a mediator that transmits motion while maintaining stability and preventing jittering or slipping during extension and retraction operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The coupling member incorporates a coupling surface with a specific curvature that matches the guiding surface on the bracket assembly. This curved surface design allows for smooth engagement and guidance during the extension and retraction movements, eliminating jittering while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Reliability

If the injection member is fixedly connected to the driving assembly or bracket, then operational stability is improved, but the design flexibility is reduced

Engineering Contradiction:

Improveoperational stabilityVSAvoidpositioning versatility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The coupling member is designed to dynamically engage with the guiding surface during operation. The coupling surface maintains stable engagement during extension and retraction while allowing the injection member to be positioned at different locations along the guiding surface, providing both operational stability and positioning versatility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The connection system is segmented into distinct components: the driving assembly, the coupling member, and the bracket assembly with guiding surface. This segmentation allows the injection member to be firmly connected during operation for stability, while the modular design enables flexible positioning and configuration adjustments.

Inventive Principle:

Principle #1Segmentation
