Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with moving functions, such as robot cleaners and movable projectors, face challenges in maintaining sensor balance during acceleration, deceleration, and changes in pitch and roll angles, leading to incorrect sensing results.
Innovation Solution
The electronic device incorporates a sensor module with a support, a hinge part for rotational connection, and a balance element to maintain balance during movement. This module includes a tilt detection sensor and electromagnets to adjust the sensor's position and maintain balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sensor is embedded in the body of the robot, then the sensor rotates together with the body during movement, but this causes the sensing direction to vary and incorrect sensing results
Solution Approach 1:
The sensor module is separated from the main body through a hinge connection, allowing the sensor support to be divided into a fixed portion (attached to main body) and a movable portion (supporting the sensor). This segmentation enables the sensor to maintain a separate orientation from the rotating body.
Solution Approach 2:
A hinge mechanism serves as an intermediary between the main body and the sensor support, enabling relative motion compensation. The hinge allows the sensor support to rotate independently from the main body, mediating the conflict between body movement and sensor orientation stability.
2Device complexity
If the sensor module is fixed rigidly to the main body, then the structure is simple, but the sensor cannot maintain balance during acceleration and deceleration
Solution Approach 1:
The sensor support is transformed from a rigid fixed connection to a dynamic hinge-connected structure. The hinge enables the sensor support to rotate and adjust its position dynamically in response to acceleration and deceleration forces, maintaining sensor balance during movement while adding minimal structural complexity.
3Measurement precision
If a balance element is added to maintain sensor balance during movement, then sensing accuracy is improved, but the device complexity increases
Solution Approach 1:
A balance element is introduced as a counterweight to offset the inertial forces acting on the sensor during acceleration and deceleration. This counterbalance mechanism compensates for the sensor's tendency to tilt, maintaining sensing accuracy while adding a single functional component rather than a complex system.
