Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the control assembly and the product body are integrated in one, then the control functions are complete, but the volume of the electronic product becomes large

Engineering Contradiction:

Improvecontrol functionsVSAvoidvolume of electronic product

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent divides the electronic product into two independent parts: a rotary control assembly and an electronic body. The control assembly contains the control component, rotating member, and magnetic detection components, while the electronic body contains the controlled components. This segmentation allows the control functions to be complete while reducing the volume of each individual component and enabling separate storage and transportation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The control assembly is extracted from the electronic body as a separate, independent unit. The control assembly can be detached and stored separately from the electronic body, allowing consumers to only carry the electronic body when the control functions are not needed, thereby reducing the overall volume requirement for storage and transportation.

Inventive Principle:

Principle #2Taking out (Extraction)

2Volume of moving object

If the control assembly is separate from the electronic body, then the volume is reduced, but the communication and control reliability may be affected

Engineering Contradiction:

Improvevolume of electronic productVSAvoidcommunication reliability

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The patent replaces traditional mechanical or wired connection systems with a wireless communication system. The control assembly and electronic body communicate through wireless signals, eliminating the need for physical connections while maintaining communication reliability. This allows the control assembly to be separate and portable without compromising the control function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If the control assembly is integrated, then the control precision is high, but the ease of storage and transportation is reduced

Engineering Contradiction:

Improvecontrol precisionVSAvoidease of storage and transportation

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

By segmenting the control assembly from the electronic body, the patent enables the control assembly to be stored separately in a compact form. The magnetic detection components and rotating member are designed to work together as a compact unit that can be easily transported and stored when not in use, while maintaining high control precision during operation.

Inventive Principle:

Principle #1Segmentation

AI summary

This application provides a rotary control assembly and an electronic product, the rotary control assembly comprises a substrate plate, a rotating member rotationally connected to the substrate plate, a magnetic member arranged on the rotating member, a magnetic signal detection member, and a control assembly arranged on the substrate plate or the rotating member; a magnetic field generated by the magnetic member changes with a rotation of the rotating member; the magnetic signal detection member is arranged on the substrate plate, and located in the magnetic field, and detects magnetic field changes of the magnetic member. The control assembly receives a magnetic field change signal detected by the magnetic signal detection member, and the magnetic field change signal is processed as a control signal. The control assembly further transmits the control signal to the electronic body to control the electronic body to execute a corresponding instruction.
