Solution Overview

Problem

Conventional cushioned remote control units, such as pillows or plush toys, face challenges in providing stable button presentation and accessibility, especially for children, due to deformation when buttons are pressed on soft surfaces and difficulties in triggering sensors with insufficient strength or small hands.

Innovation Solution

Integration of an electronic circuit within a cushioned carrier body, equipped with sensors like gyroscopes and accelerometers, allows remote control signals to be triggered by moving the entire unit, featuring a manual input unit, display via LEDs, and communication protocols like Bluetooth and Wi-Fi, with a salient part for user input and a charging system for inductive charging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If buttons are integrated into a soft cushion surface, then the remote control unit becomes comfortable and safe for users (including children), but the buttons become unstable and change position when pressed

Engineering Contradiction:
Improvecomfort and safetyVSAvoidbutton position stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent replaces mechanical button pressing with sensor-based detection. Instead of physical buttons that deform the cushion, the system uses pressure sensors, infrared sensors, or other non-mechanical sensing methods to detect user input, eliminating the stability problem while maintaining comfort

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces sensor technology as an intermediary between the user and the electronic circuit. The sensors detect user intent without requiring direct mechanical contact with unstable button elements, allowing the soft cushion to remain stable while still enabling control

Inventive Principle:
Principle #24Intermediary (Mediator)

2Use of energy by moving object

If a pressure sensor is used to detect presence, then energy consumption is reduced in stand-by mode, but children cannot trigger the sensor with insufficient hand strength

Engineering Contradiction:
Improveenergy consumptionVSAvoidsensor triggerability
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent implements multiple sensor types (pressure sensors, infrared sensors, and other sensing technologies) that can detect different forms of user interaction. This multi-functional sensing approach ensures that children can trigger the remote control through various methods such as hand warmth detection or light reflection, not just pressure

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

Solution Approach 2:

The patent changes the detection parameters of the sensors to be more sensitive to child users. Infrared sensors can detect the warmth of small hands, and the system can adjust sensitivity thresholds to accommodate weaker interaction forces while maintaining energy-efficient stand-by mode

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If the electronic circuit is fully integrated into the cushion material, then the remote control unit becomes soft and safe, but the electronic parts lack stability for reliable operation

Engineering Contradiction:
ImprovesafetyVSAvoidelectronic circuit stability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent applies different material properties to different parts of the remote control unit. The carrier body uses soft cushion material for safety, while the electronic circuit board and critical components are positioned in localized stable regions where the cushion material provides sufficient support for reliable electronic operation

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent segments the remote control unit into distinct functional zones: soft cushion areas for user contact and safety, and stabilized electronic zones for reliable circuit operation. This segmentation allows each part to optimize its properties without compromising the whole system

Inventive Principle:
Principle #1Segmentation
