Solution Overview

Problem

The existing water application devices for gardening and yard maintenance require multiple tools with different characteristics, leading to increased production costs and complexity due to the need for various specific devices.

Innovation Solution

A modular water application device design that includes a main body with interchangeable components such as an operable member and applicator head, allowing for different ergonomic and functional characteristics by attaching various panels and applicator heads, reducing the need for multiple manufacturing lines and simplifying production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manufacturers produce various different devices with various different characteristics to meet different gardening needs, then customer requirements are satisfied, but production cost and complexity increase

Engineering Contradiction:
Improvevariety of water application characteristicsVSAvoidproduction process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The water application device is divided into separate modular components: a main body and interchangeable applicator heads. Each applicator head can be detached and replaced with another, allowing the same main body to provide multiple water application characteristics (stream, jet, spray, sprinkle) through different heads, thereby reducing the need to manufacture multiple complete devices

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The main body of the device is designed with a universal interface that can accommodate multiple types of applicator heads. This allows a single main body unit to perform multiple functions by simply changing the applicator head, satisfying different gardening needs without requiring separate specialized devices for each function

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If manufacturers produce various different devices with various different characteristics to meet different gardening needs, then customer requirements are satisfied, but production cost increases

Engineering Contradiction:
Improvevariety of water application characteristicsVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting the device into a shared main body and interchangeable applicator heads, the manufacturing process can produce large quantities of a single main body design and multiple simpler applicator head variants. This reduces tooling costs, simplifies production lines, and allows economies of scale on the main body component

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The universal main body design serves as a cost-effective platform that can be mass-produced once and then paired with various applicator heads. This eliminates the need to manufacture multiple complete device variants, each requiring separate production lines and tooling, thereby significantly reducing overall production costs

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A modular water application device (10, 300) may include a main body (20, 110) graspable along a portion thereof by an operator, an operable member (30) and an applicator head (40). The main body (20, 110) may house a flow control assembly (50) configured to enable the device to execute a control function relative to flow of water through the device. The operable member (30) may be attachable to the main body (20, 110) to interface with the flow control assembly to alternately start and stop flow based on a position of the operable member (30). The applicator head (40) may be attachable to an outlet portion of the main body (20, 110) to apply water passing through the applicator head (40) based on an application characteristic of the applicator head (40). The main body (20, 110) may include a plurality of attachment portions (60) in addition to the outlet portion (24). The attachment portion may be configured to receive a rear panel (70) or front panel (72) having different functional or ergonomic characteristics.
