Solution Overview

Problem

Existing electronic device panels face challenges in clearly conveying device status due to inadequate contrast, space constraints, and cost issues, particularly with matrix displays and single LED indicators, which can confuse users and complicate button placement.

Innovation Solution

A panel with an annular sign featuring three indicia means, each an annular segment with small angular gaps, using bicolor or tricolor LEDs for clear visibility, and optionally a central button with standardized symbols, along with a process to transfer data to a computer for remote display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a matrix display is used to show graphical symbols and text information, then the information transmission capability is improved, but the space occupation and cost increase

Engineering Contradiction:
Improveinformation transmission capabilityVSAvoidpanel surface occupation
Core Design Contradiction:
Loss of informationVSArea of stationary object

Solution Approach 1:

The annular sign is segmented into multiple indicia means (at least three) arranged along the annular path, with each indicium representing a specific device status. This segmentation allows comprehensive status information to be displayed using minimal space, as each segment conveys distinct information without requiring a full matrix display.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a two-dimensional matrix display to an annular (circular) arrangement of indicia. By organizing status indicators along an annular path rather than in a grid, the design achieves efficient space utilization while maintaining clear visual distinction between different status states through angular positioning.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If several LED indicators are used to represent different device statuses, then the information display capability is improved, but the user interpretation difficulty increases due to lack of visual contrast

Engineering Contradiction:
Improvestatus information display capabilityVSAvoiduser interpretation difficulty
Core Design Contradiction:
Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent employs color changes as a primary visual differentiation mechanism. Different indicia means are assigned different colors (e.g., green for normal operation, red for error conditions, yellow for warnings), allowing users to instantly interpret device status without requiring labels or manuals. The color-coded annular segments provide intuitive visual feedback that resolves interpretation difficulties.

Inventive Principle:
Principle #32Color changes

3Adaptability or versatility

If buttons are added to the panel for device control, then the device functionality is improved, but the panel surface space is significantly occupied

Engineering Contradiction:
Improvedevice functionalityVSAvoidpanel surface space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent merges the status indication function and control function into a single integrated annular interface. The same annular sign that displays device status also serves as the control interface, with users interacting by touching or activating specific indicia. This merging eliminates the need for separate buttons, maintaining full device functionality while minimizing panel space occupation.

Inventive Principle:
Principle #5Merging (Combining)
