Solution Overview

Problem

Existing display systems lack a unified control mechanism that allows for simultaneous adjustment of screen parameters and execution of computer hotkey operations using a single input device.

Innovation Solution

A display assembly with a hotkey controller that includes a switching key and control keys, enabling switching between on-screen display mode for screen parameter adjustment and computer hotkey mode for executing computer commands. The display assembly includes a judgment unit, screen adjustment unit, instruction processing unit, and data transmission unit for signal conversion and command execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate input devices are used for display adjustment and computer control, then each device can be optimized for its specific function, but the user must manage multiple devices and signal contents cannot be shared

Engineering Contradiction:
Improvefunction-specific optimizationVSAvoidmultiple device management
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent combines display adjustment functions and computer hotkey functions into a single unified remote controller. The controller includes a switching key that enables the user to toggle between display adjustment mode and computer hotkey mode, allowing both functions to be accessed through one device rather than requiring separate input devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The remote controller is designed with multi-functionality to perform both display parameter adjustment and computer hotkey operations. By incorporating a mode switching mechanism, the single controller can adapt to different operational contexts, making it a universal control device that eliminates the need for multiple specialized input devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If a unified control device is used for both display adjustment and computer hotkey operations, then device complexity increases, but signal sharing and unified control become possible

Engineering Contradiction:
Improveunified controlVSAvoidcontroller structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The unified remote controller is segmented into distinct functional modes through a switching key mechanism. The controller can be divided into at least two operational states: display adjustment mode and computer hotkey mode. This segmentation allows the single device to handle different signal types appropriately without requiring complex integrated processing, as the switching key简单地 routes signals to the appropriate processing path.

Inventive Principle:
Principle #1Segmentation

3Reliability

If multiple input devices are used, then each device can have dedicated signal content, but time is lost switching between devices and operations cannot be shared

Engineering Contradiction:
Improvededicated signal contentVSAvoiddevice switching time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The remote controller performs preliminary action by pre-configuring both display adjustment and computer hotkey functionalities within a single device. The switching key is prepared in advance to enable rapid mode switching, eliminating the need for physical device switching. This preliminary integration allows the user to access both signal types without time loss associated with picking up or switching between separate devices.

Inventive Principle:
Principle #10Preliminary action

AI summary

A display assembly, a method for operating a display assembly and a display are provided. The display assembly includes a hotkey controller and a display. The hotkey controller includes a switching key and a plurality of control keys. The switching key is used for switching between an on-screen display mode and a computer hotkey mode. When the hotkey controller is in the on-screen display mode and one or more of the control keys are pressed, a screen adjustment command is generated; when the hotkey controller is in the computer hotkey mode and one or more of the control keys are pressed, a computer hotkey command is generated. The display includes a judgment unit, a screen adjustment unit, an instruction processing unit, and a data transmission unit. The instruction processing unit converts the computer hotkey command into a human interface device command for performing a hotkey operation on the computer.
