Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a large number of sensors are used to accurately detect and monitor object quantity and status in suspension-based support systems, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:

Improveobject quantity detection accuracyVSAvoidnumber of sensors

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The suspension support is divided into multiple sensing zones along its length, with each zone containing a sensor element. This segmentation allows the system to detect object quantity at different locations along the support, improving measurement precision without requiring a single complex sensor system. The controller processes signals from multiple segmented sensing zones to determine total object quantity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces complex mechanical counting mechanisms with sensor-based detection systems that use electrical or optical signals to detect object presence and quantity. This substitution reduces mechanical complexity while improving measurement precision through non-contact sensing capabilities.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If more sensor elements are installed on the suspension support to improve monitoring accuracy, then measurement precision is improved, but use of energy and hardware resources increase

Engineering Contradiction:

Improveinventory status detection accuracyVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The sensor elements operate in a periodic or event-driven manner rather than continuously, activating only when objects are detected or status changes occur. This periodic operation significantly reduces power consumption while maintaining measurement precision for inventory monitoring.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

Multiple sensor elements are electrically and functionally merged into a unified detection system where signals from individual sensors are combined and processed by a single controller. This merging approach reduces the total energy consumption compared to independent sensor systems while maintaining comprehensive monitoring capability.

Inventive Principle:

Principle #5Merging (Combining)

3Measurement precision

If a large number of sensors are used to monitor object quantity, then measurement precision is improved, but loss of resources and cost increase

Engineering Contradiction:

Improveobject quantity detection accuracyVSAvoidhardware resources

Core Design Contradiction:

Measurement precisionVSLoss of substance

Solution Approach 1:

The sensor elements are designed to serve multiple functions: detecting object presence, determining object quantity, and monitoring status changes. This multi-functionality reduces the need for separate specialized sensors, thereby reducing hardware resource consumption while maintaining measurement precision.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system changes the operational parameters of sensor elements based on detection needs, adjusting sensitivity, sampling rates, and activation thresholds dynamically. This parameter optimization allows accurate object quantity detection with fewer sensors, reducing hardware resource requirements.

Inventive Principle:

Principle #35Parameter changes
