Solution Overview

Problem

Existing switching devices are limited by their design, which privileges either vertical or horizontal installation configurations, leading to suboptimal user interface functionality and increased risk and cost due to manual adjustments required for different orientations.

Innovation Solution

A switching device with user interface means that allow selection of the viewing direction independently of the installation configuration, using either manual or automatic selection means such as push buttons, micro dip switches, or gravitational sensors, ensuring functional reliability and ease of use without hardware modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the display is mounted in a fixed position on the case, then the structure is simplified and reliability is improved, but the user interface functionality becomes suboptimal when installed in different orientations

Engineering Contradiction:
Improvestructural reliabilityVSAvoiduser interface functionality
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent changes the parameter of viewing direction through software control rather than physical repositioning. The control unit rotates the display image by 90 degrees based on installation orientation detection, allowing the fixed-mounted display to provide optimal viewing functionality in both vertical and horizontal configurations without compromising structural reliability

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If manual operations are performed to adjust the display angle for different installation configurations, then the user interface functionality is optimized, but the device complexity increases and reliability decreases due to additional moving parts

Engineering Contradiction:
Improveuser interface functionalityVSAvoidoperational reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical adjustment system with an electronic/software-based solution. Instead of physically rotating the display through manual operations, the control unit electronically rotates the display image based on signals from orientation detection means, eliminating moving parts and improving reliability while maintaining optimal user interface functionality

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

Solution Approach 2:

The system automatically detects the installation orientation through gravitational sensors or limit switches and autonomously adjusts the display viewing direction through software control. This self-service mechanism eliminates the need for manual intervention, reducing operational complexity and improving reliability by removing human error and mechanical wear

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the display is repositioned manually for different installation configurations, then the viewing direction is optimized, but the manufacturing cost increases due to additional moving parts and coupling means

Engineering Contradiction:
Improveviewing direction optimizationVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent substitutes mechanical repositioning mechanisms with an electronic control system. The display remains fixed-mounted, and the viewing direction is optimized through software-based image rotation controlled by orientation detection means, thereby eliminating the need for expensive moving parts, coupling mechanisms, and sealing components while reducing manufacturing complexity

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