Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple abnormal vibration sensing apparatuses are installed to detect vibrations in multiple directions, then the vibration detection capability is improved, but the device complexity and fabrication cost increase
Solution Approach 1:
The sensing rod is designed to detect vibrations in multiple directions (front-rear, left-right, and diagonal directions) through a single apparatus. The rod can rotate about its longitudinal axis and the contact sensing unit can be positioned at different locations, enabling one sensing apparatus to perform the function of multiple separate sensors would otherwise be needed.
Solution Approach 2:
Multiple vibration detection functions are merged into a single sensing apparatus. The sensing rod integrates multiple detection capabilities by allowing the contact sensing unit to detect vibrations from different directions through strategic positioning and rotation, combining what would traditionally require multiple separate sensing apparatuses into one unified device.
2Measurement precision
If multiple abnormal vibration sensing apparatuses are installed to detect vibrations in multiple directions, then the vibration detection capability is improved, but the assembly time increases
Solution Approach 1:
The sensing rod serves multiple detection purposes simultaneously. By positioning the contact sensing unit at strategic locations on the rod and allowing rotation about the longitudinal axis, a single apparatus can monitor vibrations in front-rear, left-right, and diagonal directions, eliminating the need to assemble multiple separate sensing devices.
Solution Approach 2:
The invention merges multiple vibration detection functions into one sensing apparatus, reducing the number of components that need to be assembled. The single sensing rod with strategically positioned contact sensing units replaces what would otherwise require multiple separate sensing apparatuses, thereby reducing assembly time and complexity.
3Measurement precision
If multiple abnormal vibration sensing apparatuses are installed to detect vibrations in multiple directions, then the vibration detection capability is improved, but the fabrication cost increases
Solution Approach 1:
The sensing rod is designed as a universal detection component that can monitor vibrations in multiple directions. By positioning the contact sensing unit at different locations on the rod and enabling rotation, a single apparatus performs the function of multiple separate sensors, reducing the total number of components that need to be manufactured and assembled.
Solution Approach 2:
The invention combines multiple vibration detection functions into one sensing apparatus, reducing the total component count. The sensing rod with strategically positioned contact sensing units integrates the functionality of multiple separate sensing devices, thereby reducing fabrication costs associated with manufacturing, sourcing, and assembling multiple individual components.

AI summary
A washing machine has an abnormal vibration sensing apparatus. The abnormal vibration sensing apparatus includes a limiter having at least one opened side and connected to one of a vibrating body and a fixing body, a sensing rod having one end that is received in the limiter and separated from an inner wall of the limiter, and the other end that is connected to another of the vibrating body and the fixing body, and a contact sensing unit sensing whether the limiter and the sensing rod are in contact with each other so as to sense abnormal vibration of the vibrating body. According to this construction, it is possible to easily detect abnormal vibration in a plurality of directions without increasing the number of installing abnormal vibration sensing apparatuses.
