Solution Overview

Problem

Existing hanging scales have a fixed internal structure that limits sensor mounting positions and require complex protective structures, making them unsuitable for super-thin designs.

Innovation Solution

A hanging scale sensor apparatus with an adapter beam and support base, connected via a limiting structure, allows adjustable installation and two-way protection, enabling flexible placement within the scale body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the sensor is mounted on the outer side of the scale body, then the sensor can be easily accessed and mounted, but an additional external cover is needed to cover the sensor, resulting in a complicated protective structure

Engineering Contradiction:
Improvesensor mounting easeVSAvoidprotective structure complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The adapter beam is integrated with the scale body structure, merging the sensor mounting function into the existing scale body framework. This eliminates the need for separate external covers and reduces structural complexity while maintaining easy sensor access and mounting capabilities.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the internal structure of the hanging scale is fixed, then the structure is simple and stable, but the position of the sensor mounted therein is limited

Engineering Contradiction:
Improvesensor positioning flexibilityVSAvoidinternal structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter beam is designed with adjustable positioning capabilities, allowing the sensor to be mounted at different positions along the beam. This dynamic positioning system provides flexibility in sensor placement while maintaining structural stability through the adapter beam's integration with the scale body.

Inventive Principle:
Principle #15Dynamics

3Volume of moving object

If a super-thin scale body structure is used, then the scale body occupies minimal space, but existing hanging scale sensors are not suitable

Engineering Contradiction:
Improvescale body volumeVSAvoidsensor compatibility
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The sensor mounting system is segmented into modular components: the adapter beam and the support base. This segmentation allows the sensor apparatus to be designed as a separate, compact unit that can be integrated into super-thin scale bodies without compromising sensor functionality or requiring excessive space.

Inventive Principle:
Principle #1Segmentation

4Reliability

If the adapter beam and support base are connected without limiting structure, then the assembly is simple, but the sensor apparatus cannot prevent overloading

Engineering Contradiction:
Improveoverloading preventionVSAvoidlimiting structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The limiting structure includes preset limiting members (such as limiting blocks or limiting slots) that are pre-positioned between the adapter beam and support base. These members proactively prevent excessive displacement or overloading of the sensor apparatus before harmful forces can damage the sensor, thereby ensuring reliability without requiring complex active control systems.

Inventive Principle:
Principle #9Preliminary anti-action
