Solution Overview

Problem

Modern meters often face installation challenges due to space constraints and difficult access, leading to suboptimal positioning and orientation that can result in reading errors and hinder user benefits.

Innovation Solution

A meter with a main measuring device, orientation sensor, processing unit, and display that automatically adapts the display orientation based on the meter's position relative to gravity, ensuring visibility and readability without requiring operator intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the meter is mounted in a position that satisfies integration constraints (space limitations, pipe positioning), then the meter can be installed in difficult-to-access or compact spaces, but the display orientation becomes suboptimal and readability deteriorates

Engineering Contradiction:
ImproveInstallation flexibilityVSAvoidDisplay readability
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The display orientation is made dynamic by using an orientation sensor to detect the meter's installation position and automatically adjusting the display character orientation accordingly. This allows the display to adapt to different mounting positions (horizontal, vertical, inverted) without requiring manual reconfiguration, thus maintaining readability while preserving installation flexibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs self-adjustment of the display orientation based on automatic detection of its own installation position. The processing unit receives orientation data from the sensor and autonomously reorients the display characters, eliminating the need for operator intervention and ensuring the display is always optimally oriented regardless of how the meter was installed.

Inventive Principle:
Principle #25Self-service

2Device complexity

If the display orientation is fixed during manufacturing, then the device structure remains simple, but the display may be upside down or difficult to read when the meter is installed in non-standard positions

Engineering Contradiction:
ImproveDisplay system complexityVSAvoidDisplay adaptability to installation position
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The display character orientation parameter is changed dynamically based on the detected installation position. The system modifies the orientation parameter (0°, 90°, 180°, 270°) according to the meter's mounting orientation, allowing the same display hardware to present information correctly in various installation scenarios without requiring multiple display units or complex mechanical adjustments.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The display system achieves multi-functionality by being able to present information correctly in multiple installation orientations (horizontal, vertical, inverted, different rotational positions). A single display unit with automatic orientation adjustment replaces what would otherwise require multiple specialized display configurations, making the meter universally adaptable to different mounting positions.

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