Solution Overview

Problem

Multimedia systems require intuitive and easy control of parameters like volume, bass, and track selection, but existing designs often clutter the surface with control buttons and displays, limiting design possibilities and user experience.

Innovation Solution

A control unit with a bracket that allows physical manipulation of the multimedia system relative to a neutral position, using sensors like accelerometers and gyroscopes to register movements and alter parameters, enabling intuitive control without surface-mounted controls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If control buttons and displays are provided on the surface of the multimedia system, then control functionality is achieved, but the design aesthetics and surface neutrality are compromised

Engineering Contradiction:
Improvecontrol functionalityVSAvoiddesign aesthetics
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The control buttons and displays are extracted from the surface of the multimedia system and relocated to a remote control device. This allows the multimedia system surface to maintain its neutral, aesthetically pleasing design while control functionality is preserved through the separate remote control interface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A remote control device serves as an intermediary between the user and the multimedia system. The remote control transmits control signals to the multimedia system without requiring physical buttons or displays on the system itself, thus maintaining design aesthetics while enabling control functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Shape

If control buttons and displays are removed from the surface, then design aesthetics are improved, but control intuitiveness and user feedback are reduced

Engineering Contradiction:
Improvedesign aestheticsVSAvoidcontrol intuitiveness
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The remote control device incorporates feedback mechanisms such as LED indicators, display screens, and tactile buttons that provide immediate visual and tactile feedback to the user. This maintains control intuitiveness by allowing users to see and feel their input actions, even though the physical controls are removed from the multimedia system surface.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The mechanical control interface on the multimedia system surface is replaced with a remote control device that uses wireless communication (infrared, radio frequency) to transmit control signals. This substitution maintains control functionality and intuitiveness through the remote interface while eliminating the need for surface-mounted mechanical controls.

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

3Adaptability or versatility

If multiple control elements are placed on the surface, then comprehensive parameter control is achieved, but the surface becomes cluttered and design flexibility is limited

Engineering Contradiction:
Improveparameter control capabilityVSAvoidsurface clutter
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

All control elements for parameter adjustment are extracted from the multimedia system surface and consolidated into a remote control device. This allows comprehensive parameter control capability to be maintained while the multimedia system surface remains clean and uncluttered, providing full design flexibility.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The remote control device serves as a universal control interface that can adjust multiple parameters (volume, bass, treble, track selection, etc.) through a single integrated device. This multi-functional approach maintains comprehensive control capability while eliminating the need for multiple separate control elements on the multimedia system surface.

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