Solution Overview

Problem

Stick vacuum cleaners with cameras and displays struggle to conserve battery power due to continuous activation of these components during sweeping of easily accessible areas, leading to reduced energy efficiency.

Innovation Solution

A stick vacuum cleaner design featuring a camera and display that remain dormant during normal use, with an angular position sensor and control unit that activate these components only when the brush head angle falls below a predetermined limit, ensuring efficient battery use by adjusting the display's angle relative to the body for ergonomic viewing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the camera, light source and display are continuously activated during sweeping, then the user can always see the area being swept, but the battery power is depleted rapidly

Engineering Contradiction:
Improvevisibility of swept areaVSAvoidbattery power consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The camera, light source and display are activated periodically based on detected sweeping conditions rather than continuously. The control unit activates these components only when dark or narrow areas are detected, allowing the system to conserve energy during normal sweeping while providing visual feedback when needed.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The angular position sensor provides feedback about the brush head's position and angle to the control unit. This feedback enables the system to intelligently determine when to activate the camera, light source and display based on the detected angle, optimizing both energy consumption and user visibility needs.

Inventive Principle:
Principle #23Feedback

2Use of energy by moving object

If the camera and display are activated only when needed, then battery life is extended, but the user may not see dark areas that require illumination

Engineering Contradiction:
Improvebattery power consumptionVSAvoidvisibility of dark areas
Core Design Contradiction:
Use of energy by moving objectVSIllumination intensity

Solution Approach 1:

The angular position sensor continuously monitors the brush head angle and provides feedback to the control unit. When the sensor detects angles indicating the brush is in a dark or narrow area, the control unit activates the light source and display, ensuring illumination is provided precisely when and where needed while conserving battery power during normal sweeping.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system uses the angular position sensor to automatically detect when illumination is needed and activates the light source and display without user intervention. The system serves itself by monitoring its own operational state and making appropriate adjustments to lighting and display activation.

Inventive Principle:
Principle #25Self-service

3Device complexity

If the display angle is fixed, then the device structure is simple, but the user cannot maintain an ergonomic viewing position when sweeping under furniture

Engineering Contradiction:
Improvedisplay mounting structureVSAvoidergonomic viewing position
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The display is mounted on a rotatable hinge that allows it to change its angle dynamically. The DC motor adjusts the display angle in real-time based on feedback from the angular position sensor, enabling the display to maintain an ergonomic position relative to the user even when sweeping under furniture or at different angles.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The angular position sensor provides continuous feedback about the brush head's angular position to the control unit. The control unit uses this feedback to adjust the display angle via the DC motor, ensuring the display remains optimally positioned for the user's line of sight regardless of the sweeping angle or position.

Inventive Principle:
Principle #23Feedback
