Solution Overview

Problem

Households face difficulties in finding and scheduling competent individuals for part-time, specialized household services, while service providers struggle to connect with clients due to irregular needs and logistical issues.

Innovation Solution

A system and method for an In-home Assistant Service that collects information on service providers' skills and availability, allowing households to submit detailed job requests, with a matching algorithm that screens providers based on essential and secondary criteria for efficient booking and confirmation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If households seek specialized part-time service providers, then service quality and competence are improved, but the difficulty of locating and scheduling providers increases

Engineering Contradiction:
Improveservice qualityVSAvoiddifficulty of locating and scheduling
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a marketplace platform as an intermediary that connects households with service providers. The platform collects provider information, skills, and availability, then matches providers to household requests using automated algorithms. This intermediary system resolves the contradiction by making specialized providers easily locatable and schedulable without compromising service quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces manual searching and scheduling processes with automated computer-based systems. The matching algorithm automatically screens providers against essential and secondary criteria, and the electronic booking system automates scheduling and confirmation. This substitution of mechanical manual processes with automated systems improves ease of operation while maintaining reliable service matching.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If service providers accept irregular part-time work, then flexibility and income opportunities are improved, but logistical coordination difficulties increase

Engineering Contradiction:
ImproveflexibilityVSAvoidlogistical coordination
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic availability scheduling where service providers can specify their available time slots and the system automatically matches them with appropriate requests. The electronic booking system dynamically updates provider schedules and sends automated reminders, adapting to irregular part-time work patterns. This dynamic approach maintains flexibility while reducing logistical coordination complexity through automation.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If detailed criteria are used to match households with providers, then matching precision is improved, but the complexity of the screening process increases

Engineering Contradiction:
Improvematching precisionVSAvoidscreening process complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the matching criteria into essential criteria (must-have qualifications) and secondary criteria (preferred qualifications). The system first screens providers against essential criteria to create a qualified pool, then applies secondary criteria to select the best match. This segmentation reduces screening complexity by breaking down the detailed matching process into manageable stages while maintaining high matching precision.

Inventive Principle:
Principle #1Segmentation

AI summary

A system and method are disclosed for the operation of an In-home Assistant Service. The service provides a marketplace to connect households with assistants for frequent and specialized jobs. The service collects profile data of potential assistants including multiple skills the assistant can provide. It also enables the household to provide detailed request criteria. A locate process is then performed to determine, which assistants best meet the identified criteria.
