Solution Overview

Problem

Existing squeegee systems are limited by their fixed installation, leading to issues with cleanliness and availability of cleaning fluid, especially in non-stationary environments like vehicle interiors, which affects driver visibility and safety.

Innovation Solution

A portable squeegee system with a carrying strap and a container for cleaning fluid, allowing for convenient and portable cleaning of vehicle surfaces, including windows, headlights, and mirrors, ensuring visibility and safety by providing a self-contained cleaning solution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a squeegee station is permanently installed at a location, then cleaning fluid is always available at that station, but the system lacks portability and cannot be moved to different locations

Engineering Contradiction:
Improveavailability of cleaning fluidVSAvoidportability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The squeegee apparatus is nested within a container that holds cleaning fluid. The container serves as a portable reservoir that can be carried to different locations, while the squeegee mechanism is integrated inside the container structure, allowing the entire system to be transported as a single unit.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The system is divided into separable components: a container holding cleaning fluid, a squeegee mechanism, and a carrying strap. These segments can be assembled and disassembled, allowing the container with fluid to be transported independently or with the squeegee attached, providing flexibility in portability while maintaining fluid availability.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a squeegee container is made portable with a carrying strap, then the system can be moved to different locations, but the structural complexity increases

Engineering Contradiction:
ImproveportabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The carrying strap is integrated into the container structure, merging the portability feature with the existing container design. The lid of the container incorporates attachment points for the strap, combining multiple functions (fluid containment, squeegee housing, and portability) into a single integrated structure rather than adding separate components.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If cleaning fluid is stored in a portable container, then the system can be used anywhere, but the container requires secure locking mechanisms to prevent fluid leakage

Engineering Contradiction:
ImproveportabilityVSAvoidlocking mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The locking mechanism is designed to automatically engage when the lid is closed, using the lid's own closure action to trigger the lock. The tab and slot geometry causes automatic locking without requiring separate manual locking operations, making the security feature self-activating rather than requiring additional user intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

A tab-slot locking mechanism serves as an intermediary between the lid and container body, providing a simple mechanical interface that secures the lid in place. The tab on the lid engages with a slot in the container, creating a reliable locking connection through a straightforward geometric interface rather than complex fastening systems.

Inventive Principle:
Principle #24Intermediary (Mediator)
