Solution Overview

Problem

Existing load regulation devices, particularly those with integrated display screens, face challenges in effectively incorporating a push switch function, leading to structural unreliability and difficulty in integrating the push switch mechanism.

Innovation Solution

A load regulation device featuring a knob frame with an elastic portion that deforms upon force application, triggering a switch component, and returns to its original position to release the trigger, with the switch component positioned adjacent to the display assembly, eliminating the need for a hard switch on the display screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a push switch function is integrated into a knob assembly with display screen, then the functionality is enhanced, but the structural reliability deteriorates due to difficulty in integrating the push switch mechanism

Engineering Contradiction:

Improvepush switch function integrationVSAvoidstructural reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines the push switch trigger mechanism with the elastic portion of the knob frame, merging two functions (knob operation and switch triggering) into a single integrated structure. The elastic portion serves both as part of the knob assembly and as the trigger mechanism for the push switch, eliminating the need for separate switch components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The elastic portion of the knob frame is designed to serve multiple functions: it provides the elastic response for normal knob operation and simultaneously acts as the trigger component for the push switch function. This multi-functional design simplifies the overall structure while maintaining reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a hard switch is placed on the display screen for push switch function, then the switch triggering is simplified, but the structural reliability deteriorates and the display screen becomes vulnerable

Engineering Contradiction:

Improveswitch triggeringVSAvoiddisplay screen integrity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent extracts the switch trigger function from the display screen and relocates it to the elastic portion of the knob frame. This separates the display function from the switch triggering function, protecting the display screen from mechanical stress while maintaining ease of operation through the elastic trigger mechanism.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The elastic portion acts as an intermediary between the user's push action and the switch component. Instead of directly pressing a hard switch on the display screen, the user's force is transmitted through the elastic portion, which then triggers the switch, providing mechanical advantage and protecting the display screen.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the switch component is positioned away from the display assembly, then the display screen is protected, but the device complexity increases due to longer trigger components

Engineering Contradiction:

Improvedisplay screen protectionVSAvoidtrigger component structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the switch trigger component with the elastic portion of the knob frame, eliminating the need for separate, long trigger components. The elastic portion itself becomes the trigger mechanism, reducing structural complexity while maintaining display screen protection through proper component positioning.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A load control device for regulating an electrical load includes: a support component including a connection portion; a knob frame including a gripping portion and an elastic portion, the gripping portion at least partially surrounding the support component and configured to drive the knob frame to rotate in response to a rotational force acting thereon, the elastic portion configured to move toward the connecting portion in response to the knob frame moving in a first direction, thereby undergoing elastic deformation; a display assembly disposed on a side surface of the knob frame facing away from the support component; a circuit board component disposed adjacent the display assembly; a switch component disposed on the circuit board component, for controlling the load in response to triggering and releasing the triggering; a switch trigger component for applying the triggering and releasing the triggering to the switch trigger component; and an adjustment component for adjusting the load in response to the rotation of the knob frame. The load control device allows for a more flexible arrangements of the switch trigger component, and makes the structure more reliable. A system including the load control device is also disclosed.
