Solution Overview

Problem

Existing surface cleaning implements often fail to prevent incorrect container attachment, leading to potential damage and user exposure to unintended substances, and lack user control over fluid dispensing, especially when cleaning fabric surfaces like carpets.

Innovation Solution

A surface cleaning implement with a container receiver and nozzle assembly featuring a valve or locking mechanism operated by a container member, ensuring correct container fitment and user-controlled dispensing of cleaning compositions, including a rotation valve and locking system to prevent over-rotation and accidental discharge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple container attachment system is used, then the device complexity is reduced, but incorrect container attachment cannot be prevented

Engineering Contradiction:
Improvecontainer attachment systemVSAvoidcontainer fitment prevention
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The container member and receiving orifice are designed with asymmetric geometries including bayonet projections and complementary recesses. This asymmetric design ensures that only containers with the correct orientation and configuration can be properly attached to the implement, preventing incorrect container attachment while maintaining a relatively simple overall system structure.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

A valve member acts as an intermediary between the container and the fluid conduit system. The valve member includes a valve body with a receiving orifice that interfaces with the container member, providing both a mechanical connection interface and a fluid control function. This intermediary component enables correct container fitment verification while controlling fluid dispensing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a valve system is added to control fluid dispensing, then user control over dispensing is improved, but the device complexity increases

Engineering Contradiction:
Improvefluid dispensing controlVSAvoidvalve system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The valve control function is merged with the container attachment mechanism. The valve member is integrated into the container receiver assembly, and the valve operation is coupled with the container insertion and rotation motions. This merging allows users to control fluid dispensing through the existing container attachment operations without adding separate complex control mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The valve system utilizes dynamic motion sequences during container attachment. The valve member transitions between different positions (closed, opening, open) as the container is inserted and rotated into place. This dynamic operation allows the valve to automatically respond to container attachment status, providing user control through natural operational sequences rather than static control mechanisms.

Inventive Principle:
Principle #15Dynamics

3Reliability

If a locking mechanism is implemented, then container disconnection is prevented, but the ease of container removal is reduced

Engineering Contradiction:
Improvecontainer connection stabilityVSAvoidcontainer removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking mechanism operates through periodic cyclic motions during container attachment and removal. The bayonet-style connection requires rotation in one direction to engage the lock, and rotation in the opposite direction to disengage it. This periodic action provides strong locking during use while maintaining relatively easy removal through simple reverse rotation, avoiding the need for complex tool-based removal systems.

Inventive Principle:
Principle #19Periodic action
