Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If actuator modules are mounted using a complex mounting device with multiple support brackets and alignment features, then the manufacturing precision and positioning accuracy improve, but the device complexity increases

Engineering Contradiction:
Improvepositioning accuracy of actuator modulesVSAvoidcomplexity of mounting device
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The mounting device is segmented into multiple support brackets (5), each independently mounted to support bars (21) and each providing localized support at grid nodes. This segmentation allows each bracket to be a simple, standardized component while collectively achieving precise positioning of actuator modules through their coordinated arrangement at regular intervals.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If actuator modules are firmly fixed in position, then the stability of the transport device improves, but the adaptability and flexibility for reconfiguration decrease

Engineering Contradiction:
Improvestability of actuator module positioningVSAvoidflexibility of transport device configuration
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The support brackets (5) are designed as universal mounting elements that can be positioned at various locations along the support bars (21) and can accommodate different actuator module configurations. The standardized interface and grid-based arrangement allow the same mounting structure to support different numbers and arrangements of actuator modules, providing both stable fixation and reconfiguration flexibility.

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

3Strength

If multiple support brackets are used to hold actuator modules, then the mechanical strength and support stability improve, but the ease of assembly and disassembly decreases

Engineering Contradiction:
Improvesupport strength of mounting structureVSAvoidease of assembly of transport device
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The support brackets (5) are pre-mounted to the support bars (21) at predetermined positions corresponding to grid nodes before the actuator modules are installed. This preliminary arrangement creates a ready-made, stable support framework that simplifies the subsequent assembly of actuator modules, as they can be directly placed onto the pre-positioned brackets without requiring complex real-time alignment procedures.

Inventive Principle:
Principle #10Preliminary action
