1Adaptability or versatility

If multiple input methods are integrated into a single input area, then the device can support diverse input types, but the input areas overlap and cause signal interference leading to delayed response

Engineering Contradiction:

Improveinput method diversityVSAvoidresponse speed

Core Design Contradiction:

Adaptability or versatilityVSSpeed

Solution Approach 1:

The input area is segmented into multiple distinct input areas, each dedicated to a specific input method. The controller identifies the type of input signal and determines the corresponding input area, ensuring that signals are processed in their designated zones without interference from other input methods, thereby maintaining fast response times while supporting diverse input types.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the input area are assigned different functional qualities based on the input method used. Each input area is optimized for its specific signal type (e.g., electromagnetic pen vs. finger touch), allowing each zone to process its designated signals efficiently without being affected by signals from other input methods.

Inventive Principle:

2Area of stationary object

If multiple input methods share the same input area, then space is utilized efficiently, but signal detection becomes inaccurate due to overlapping signals

Engineering Contradiction:

Improveinput area utilizationVSAvoidsignal detection accuracy

Core Design Contradiction:

Area of stationary objectVSMeasurement precision

Solution Approach 1:

The input area is divided into multiple non-overlapping input areas, each dedicated to a specific input method. This segmentation ensures that signals from different input methods are detected in their respective zones without interference, maintaining high detection accuracy while still utilizing the entire input area through proper spatial organization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The controller acts as an intermediary that receives input signals, identifies their type, and routes them to the appropriate input area for processing. This mediation ensures that even though multiple input methods are supported, each signal is processed in its designated zone, preventing cross-interference and maintaining detection precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the entire input area detects all input signals, then comprehensive input support is achieved, but synchronous operation cannot be maintained due to signal conflicts

Engineering Contradiction:

Improveinput signal supportVSAvoidoperational synchrony

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The input area is segmented into multiple dedicated input areas, each assigned to a specific input method. This segmentation allows the system to maintain stable, synchronous operation within each input area while supporting multiple input methods across the entire device. Each input area operates independently according to its signal type, preventing conflicts that would disrupt operational synchrony.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically determines which input area is active based on the type of input signal received. The controller adapts by identifying the signal type and routing it to the appropriate input area, allowing the system to maintain stable and synchronous operation for each input method while supporting diverse input types through dynamic signal routing.
