Solution Overview

Problem

Existing vinyl turntables are uncomfortable for DJs to use during performance as the strobe dots on the platter edge are abrasive, making it difficult to control the rotation speed with finger control.

Innovation Solution

A turntable platter configuration with a groove on the edge for ergonomic finger control and regularly spaced shapes for strobe monitoring, allowing DJs to comfortably alter rotation speed while maintaining traditional functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If regularly spaced relief structures (strobe dots) are added to the platter edge for speed monitoring, then the platter provides visual feedback for RPM control, but the relief structures become abrasive and uncomfortable for DJ finger control

Engineering Contradiction:

Improvespeed monitoring accuracyVSAvoidfinger control comfort

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The platter edge is divided into two distinct zones: an upper portion with relief structures for strobe monitoring and a lower portion with a groove for comfortable finger control. Each zone has optimized local properties - the upper portion provides visual feedback while the lower portion provides tactile comfort, resolving the contradiction between measurement precision and ease of operation.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The platter edge profile is segmented into multiple functional portions: an upper portion containing regularly spaced relief structures for strobe light reflection, and a lower portion with a groove for finger placement. This segmentation allows each portion to independently fulfill its specific function without interfering with the other, enabling both accurate speed monitoring and comfortable manual control.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the platter edge is made smooth for comfortable finger control, then DJ performance comfort is improved, but the ability to provide visual speed feedback through strobe dots is lost

Engineering Contradiction:

Improvefinger control comfortVSAvoidspeed monitoring capability

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

Different portions of the platter edge are assigned different surface qualities: the upper portion has relief structures for optical feedback, while the lower portion has a smooth groove for tactile comfort. This local differentiation resolves the contradiction by providing both speed monitoring capability and finger control comfort in their respective zones.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The platter edge is segmented vertically into functional zones - the upper portion maintains relief structures for strobe monitoring while the lower portion incorporates a groove for comfortable finger placement. This segmentation enables the platter to simultaneously provide both visual speed feedback and tactile comfort during DJ manipulation.

Inventive Principle:

Principle #1Segmentation

3Manufacturing precision

If the platter edge is designed with relief structures for strobe monitoring, then speed control accuracy is improved, but the platter becomes abrasive during beat matching operations

Engineering Contradiction:

Improverotation speed accuracyVSAvoidabrasion to DJ fingers

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The platter edge features localized quality differentiation: the upper portion contains relief structures optimized for strobe light reflection and speed accuracy, while the lower portion provides a smooth groove that eliminates abrasion during finger-based beat matching operations. This resolves the contradiction between manufacturing precision and reduction of harmful factors.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The platter edge profile is segmented into functional portions where the upper portion with relief structures provides accurate speed monitoring while the lower groove portion provides an non-abrasive surface for finger control during beat matching, eliminating the harmful abrasive effect while preserving speed control accuracy.

Inventive Principle:

Principle #1Segmentation
