Solution Overview

Problem

Existing portable devices for treating insect bites or stings using piezoelectric technology face challenges in complex and time-consuming assembly processes, leading to increased production costs and potential quality issues due to the use of multiple half-shells, which can result in inconsistent color and structural integrity problems.

Innovation Solution

A portable device with a monolithic containing body that houses the piezoelectric element, actuating element, and discharge area, featuring a single-piece shell with a guide and housing portion for precise alignment and snap closure, reducing assembly complexity and enabling easier production while ensuring correct component positioning and ergonomic design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a complex multi-piece shell construction is used, then the device can accommodate multiple components, but the assembly time and production cost increase significantly

Engineering Contradiction:
Improveshell constructionVSAvoidassembly time
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent merges multiple separate shell pieces into a single monolithic shell structure. This single shell integrates the housing, guide portions, and positioning features that were previously distributed across multiple components, thereby eliminating assembly steps while maintaining all necessary functional capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The monolithic shell serves multiple functions simultaneously: it provides structural housing, incorporates guide portions for component alignment, integrates positioning features, and maintains ergonomic form factors. This multi-functionality eliminates the need for separate specialized components.

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

2Ease of manufacture

If multiple half-shells are assembled together, then the device can be manufactured modularly, but quality consistency deteriorates due to color variations and alignment issues

Engineering Contradiction:
Improvemodular manufacturingVSAvoidquality consistency
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

By combining multiple half-shells into a single monolithic shell manufactured as one piece, the patent eliminates interfaces between components that cause color mismatches and alignment variations. The single-piece construction ensures uniform material properties and consistent appearance across the entire device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The monolithic shell is constructed from homogeneous material throughout, ensuring uniform color, texture, and physical properties. This eliminates the heterogeneity introduced by assembling multiple parts with potential variations in material batches, storage conditions, or manufacturing tolerances.

Inventive Principle:
Principle #33Homogeneity

3Adaptability or versatility

If numerous components are assembled and aligned, then the device achieves complete functionality, but the production cost increases due to labor-intensive processes

Engineering Contradiction:
Improvedevice functionalityVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent combines multiple functional components into the monolithic shell structure itself, eliminating the need for separate assembly operations. The guide portions, housing features, and positioning elements are integrated directly into the shell during its formation process, reducing manual labor and assembly complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The monolithic shell is pre-formed with all necessary guide portions, positioning features, and structural elements integrated during its initial manufacturing process. This preliminary incorporation of alignment and positioning features eliminates subsequent assembly and alignment operations.

Inventive Principle:
Principle #10Preliminary action
