Solution Overview

Problem

Existing portable sprayers lack intuitive and comfortable attachment and removal mechanisms to belt elements, often requiring complex adjustments and modifications to the sprayer housing.

Innovation Solution

A portable sprayer design featuring a resiliently deformable belt holder with a mounting section, intermediate section, and holding section that allows for a 180° angled attachment to a belt element without modifying the sprayer housing, enabling easy and secure fastening and removal by displacing the belt element or sprayer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional belt mount is used that extends toward one end of the housing, then the sprayer can be attached to a belt element, but the attachment is not intuitive and requires complex adjustments

Engineering Contradiction:
Improveintuitiveness of attachment and removalVSAvoidcomplexity of attachment mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The belt holder is inverted by 180° compared to conventional designs. Instead of extending toward one end of the housing, the holding section extends toward the opposite end, with the intermediate section bridging between them. This inversion creates an intuitive attachment mechanism where the belt element naturally slides between the holding section and intermediate section without requiring complex adjustments or modifications to the housing.

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If the belt holder extends along the housing toward one end, then the structure is simple, but the attachment angle does not accommodate user preferences

Engineering Contradiction:
Improveattachment angle orientationVSAvoidbelt holder structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The belt holder is segmented into three distinct sections: a mounting section mounted on the housing, an intermediate section extending from the mounting section toward one end region, and a holding section extending from the intermediate section toward the opposite end region. This segmentation allows the belt holder to achieve 180° angled attachment orientation while maintaining structural simplicity and avoiding modifications to the housing.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the holding section and intermediate section are connected, then the sprayer is securely fastened to the belt element, but removal requires deliberate action

Engineering Contradiction:
Improvesecurity of attachmentVSAvoidease of removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The belt holder utilizes resilient deformability in its structure, allowing dynamic adjustment during attachment and removal. The holding section and intermediate section are connected in a way that permits controlled movement: during attachment, the sections deform to accommodate the belt element, securing it firmly; during removal, the same resilient properties allow deliberate displacement in the extension direction to release the belt element easily.

Principle #15Dynamics

AI summary

The invention relates to a portable spray device (10), comprising: an elongate housing (12) having two end regions (14, 16) with respect to its longitudinal extent; and a belt holder (30) having at least one mounting section (32), an intermediate section (34), and a holding section (36), wherein the belt holder is mounted on the housing by the mounting section, wherein the intermediate section adjoins the mounting section and extends in the direction of a first end region of the end regions, and wherein the holding section adjoins the intermediate section and extends in the direction of a second end region of the end regions, such that a belt element (52) can be inserted between the holding section and the intermediate section by displacement in an insertion direction (54) facing the first end region of the end regions, in order to fasten the spray device to the belt element.
