Solution Overview

Problem

Existing display systems require an additional WLAN module for communication with human input devices, increasing product costs and limiting the use of the second WLAN module to only recognize devices as HID, preventing network device communication.

Innovation Solution

A display apparatus allocates a dedicated communication channel for human input devices and restricts other network devices from connecting to it, allowing simultaneous communication with an access point using the same WLAN module, eliminating the need for a dedicated module for HID communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a second WLAN module is added for HID communication, then communication with human input devices is enabled, but product cost increases

Engineering Contradiction:

Improvecommunication capability with HIDVSAvoidnumber of WLAN modules

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes a single WLAN module universal by enabling it to perform multiple functions: it can communicate with both access points (network devices) and human input devices (HID) through channel allocation. The WLAN module dynamically allocates different communication channels for different device types, eliminating the need for separate dedicated modules and reducing overall system complexity while maintaining full communication capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a second WLAN module is added for HID communication, then HID communication is possible, but product cost increases

Engineering Contradiction:

ImproveHID communication capabilityVSAvoidnumber of WLAN modules

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent merges the functionality of two separate WLAN modules (one for AP communication and one for HID communication) into a single WLAN module. By implementing channel allocation mechanisms, the single module can simultaneously handle both types of communication, thereby reducing the quantity of hardware components and lowering product cost.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the second WLAN module is used for HID communication, then HID data transmission is enabled, but the module cannot communicate with network devices

Engineering Contradiction:

ImproveHID data input capabilityVSAvoidnetwork device communication capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent segments the communication functionality by allocating different communication channels within a single WLAN module. One channel is dedicated to HID communication while another channel handles AP/network device communication. This channel segmentation allows the WLAN module to simultaneously support both HID data input and network device communication without interference, resolving the mutual exclusivity problem.

Inventive Principle:

Principle #1Segmentation
