Solution Overview

Problem

Existing temperature-controlled cup holders for vehicles are inefficient in terms of energy consumption and lack effective visual feedback for temperature settings, which can lead to user safety concerns and discomfort.

Innovation Solution

A cup holder arrangement with a control unit and RGB lighting system that adjusts color gradient based on the relative temperature setting, providing intuitive temperature feedback and preventing user injury from residual heat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If temperature-controlled cup holders are implemented, then user comfort and functionality are improved, but energy consumption increases

Engineering Contradiction:
Improveuser comfortVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent implements a feedback mechanism where a temperature sensor continuously monitors the cup holder temperature and sends signals to the control unit. The control unit adjusts the heating or cooling operation based on this feedback, ensuring energy is only consumed when temperature adjustment is needed, thus resolving the contradiction between user comfort and energy consumption.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically changes operational parameters (heating/cooling power levels) based on the temperature difference between the setpoint and actual temperature. By adjusting the degree of temperature control rather than maintaining constant high-power operation, the system reduces energy consumption while maintaining user comfort.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If visual temperature indicators are added to cup holders, then user safety and information feedback are improved, but device complexity increases

Engineering Contradiction:
Improveuser safetyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses color-changing LEDs to indicate different temperature states and operational modes of the cup holder. Different colors represent different temperature levels or operational states, providing intuitive visual feedback to users without requiring complex display systems or multiple indicator components, thus improving safety while minimizing complexity increase.

Inventive Principle:
Principle #32Color changes

3Loss of information

If RGB lighting system is integrated into cup holder, then visual feedback and user interface are improved, but manufacturing cost and device complexity increase

Engineering Contradiction:
Improvevisual feedbackVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The RGB lighting system is designed to serve multiple functions: indicating temperature levels, showing operational status, and providing user interface feedback. By consolidating these functions into a single multi-functional lighting system rather than separate indicators for each function, the patent reduces overall device complexity while maintaining comprehensive visual feedback capabilities.

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

AI summary

The cup-holder arrangement (1) has a lighting unit (5) fixed into a cup-holder (3) and provides red green blue lighting. A control unit (7) controls color gradient and light intensity of the lighting unit as functions of a temperature setting of the cup-holder. The cup-holder is a temperature-adjustable cup-holder for heating or cooling the contents of the cup-holder. A human-machine interface activates or sets the control unit. A relative temperature corresponds to temperature difference between target-temperature and actual temperature, which are the absolute temperatures of the cup-holder. An independent claim is included for a method for operating a cup-holder arrangement.
