Solution Overview

Problem

Domestic appliances, such as floor treatment robots and personal weighing scales, often occupy significant space when stored together, leading to inefficient use of room space.

Innovation Solution

Integration of a load cell system within the floor treatment robot's housing to enable weight measurement, allowing the appliance to function as a personal weighing scale, either when stationary or at the base station, thereby reducing space requirements by combining two functions into one device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate appliances (floor treatment robot and personal weighing scale) are stored in the same room, then both appliances can be easily accessed, but the space requirement for storage increases

Engineering Contradiction:
ImproveAccessibility of appliancesVSAvoidStorage space requirement
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent combines a personal weighing scale with a floor treatment robot into a single integrated device. The load cell measuring device is incorporated into the robot's housing, allowing the same appliance to perform both cleaning functions and weight measurement functions, thereby eliminating the need for separate storage space for two distinct appliances

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The floor treatment robot is designed with multi-functionality by integrating a weighing scale capability. The device can switch between its primary cleaning function and a secondary weight measurement function, making it a universal appliance that serves multiple purposes and reduces the need for specialized single-function devices

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

2Adaptability or versatility

If the weighing function is integrated in the floor treatment appliance, then the appliance can measure body weight independently of its location, but the device complexity increases

Engineering Contradiction:
ImproveWeight measurement capabilityVSAvoidStructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The floor treatment robot utilizes its own structural components (housing and support points) to serve the additional function of weight measurement. The existing load-bearing structure is instrumented with load cells, allowing the robot to measure weight without requiring a separate weighing platform or additional support infrastructure

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
