Solution Overview

Problem

Display apparatuses require multiple user inputs to perform operations and lack mechanisms to prevent unintended operations, making them inconvenient and difficult for users to confirm if intended actions are executed based on their inputs.

Innovation Solution

A display apparatus with a touch receiver, sensor, and processor that detects user input and environmental states to minimize touch inputs, prevent unintended operations, and intuitively indicate if operations are user-intended by controlling actions based on preset states, positions, and postures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple user inputs are required to perform operations, then operation accuracy can be improved, but ease of operation deteriorates

Engineering Contradiction:

Improveoperation accuracyVSAvoiduser input convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by detecting user position and environmental states before the actual operation. The processor identifies whether a touch input is intended based on pre-detected position information and environmental conditions, so that when the user makes a touch input, the system already knows whether to execute the operation or not, eliminating the need for multiple confirmation inputs

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary mechanism using position detection and environmental state detection as intermediaries between the user's touch input and the operation execution. These intermediaries (position detection module, environmental state detection module) evaluate whether the touch input should trigger an operation before execution, acting as a filter that prevents unintended operations while maintaining ease of use for intended actions

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the display apparatus performs operations based on touch input, then productivity is improved, but harmful factors increase due to unintended operations

Engineering Contradiction:

Improveoperation execution speedVSAvoidunintended operations

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system applies preliminary anti-action by detecting environmental states and user position before the touch input occurs. The processor proactively identifies conditions that would lead to unintended operations (such as when the display apparatus is being moved) and prepares countermeasures in advance. When a touch input is detected, the system immediately checks the pre-detected environmental state and position information to determine whether to execute the operation, thereby preventing harmful unintended operations while maintaining efficient execution for intended actions

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The system implements feedback mechanisms where the processor continuously monitors environmental states and user position, using this information to feedback control whether to execute operations based on touch inputs. The environmental state detection module and position detection module provide continuous feedback to the processor, which adjusts operation execution accordingly, creating a closed-loop system that prevents unintended operations while maintaining high productivity

Inventive Principle:

Principle #23Feedback

3Device complexity

If the display apparatus lacks state detection, then device complexity is reduced, but reliability of operation execution deteriorates

Engineering Contradiction:

Improvesystem structure simplicityVSAvoidoperation execution accuracy

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system achieves multi-functionality by having the processor perform multiple functions: it processes touch inputs, detects environmental states, determines user position, and decides whether to execute operations. By consolidating these functions in the processor rather than adding separate dedicated hardware for each function, the system improves reliability through comprehensive state detection while keeping device complexity relatively low

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system replaces complex mechanical or hardware-based state detection mechanisms with software-based processing. Instead of using separate physical sensors for every possible state, the processor uses software algorithms to analyze available data (touch coordinates, environmental sensor data, movement information) to determine user intent and operational context, thereby improving reliability through sophisticated software analysis rather than additional hardware complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
