Solution Overview

Problem

Existing car wash systems fail to effectively clean the bristles of handle brush heads due to limited cleaning access, often resulting in unsatisfactory outcomes.

Innovation Solution

A handle brush head receiving container with an insertion opening and a cleaning opening designed to allow bristles to extend partially out, featuring an internal guide mechanism for secure handling and a cleaning mechanism that ensures thorough bristle exposure, along with optional features like a liquid intake and retention elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the container has a lateral slot for cleaning the brush head, then the brush head can be cleaned with washing fluid or water, but the cleaning results are unsatisfactory because cleaning is only possible from the side

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidcleaning access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent transitions from lateral (side) cleaning access to top-down cleaning access by positioning the cleaning opening at the top of the container. This dimensional change allows the high-pressure jet to approach the brush head from above, enabling the bristles to extend upward and be cleaned more effectively from multiple angles rather than being limited to side-only access.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The container is segmented into distinct functional zones: an insertion opening at the top for loading brush heads, a cleaning opening also at the top for cleaning operations, and an internal guide structure. This segmentation allows independent optimization of each function, with the cleaning opening specifically designed to allow bristles to extend outward for effective high-pressure cleaning.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the brush head is inserted into a virtually closed container, then the brush head is securely held, but the bristles cannot be effectively exposed for thorough cleaning

Engineering Contradiction:
Improvebrush head retentionVSAvoidbristle cleaning thoroughness
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The container wall is designed with differentiated local qualities: most of the container wall is closed to provide secure retention and structural integrity, while the cleaning opening region is locally opened to allow bristle exposure. This localized opening maintains overall container security while enabling effective cleaning access where needed.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The internal guide structure acts as an intermediary element between the closed container environment and the cleaning process. It positions and holds the brush head while allowing the bristles to extend through the cleaning opening, mediating between the conflicting requirements of secure containment and effective bristle exposure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the container is designed as a closed structure, then it provides secure storage for the brush head, but it prevents effective cleaning of the bristles from multiple angles

Engineering Contradiction:
Improvecontainer structural integrityVSAvoidbristle accessibility for cleaning
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The cleaning opening is positioned at the top of the container rather than on the side, changing the spatial dimension of access. This top-down approach allows bristles to extend vertically outward from the container, enabling effective cleaning from above while maintaining the closed structure's structural integrity for secure storage.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Handle brush head receiving container in/for vehicle, in particular car, washing facilities, with a receiving base body which has at least one insertion opening for inserting a handle brush head of a handle brush with bristles, and at least one cleaning opening corresponding to the insertion opening for cleaning the handle brush head and/or its bristles, characterized in that the cleaning opening is designed such that the bristles of the handle brush head extend at least partially out of the cleaning opening during use.
