Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If complex corner profiles with hollow structures are used, then structural strength is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvestructural strengthVSAvoiddevice complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The corner profile is segmented into a U-shaped base element and separate connecting elements that attach to the load carrier structure. This segmentation simplifies the main corner profile while distributing connection functions to separate standardized components, reducing overall device complexity while maintaining structural integrity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The U-shaped corner elements serve multiple functions: they provide structural support, enable detachable connections, and allow for standardized assembly. This multi-functionality reduces the need for specialized complex components, simplifying the overall system while maintaining strength

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

2Ease of manufacture

If standardized connecting elements are used, then ease of manufacture and cost-effectiveness are improved, but adaptability to different cargo configurations may be limited

Engineering Contradiction:
Improveease of manufactureVSAvoidadaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The system employs detachable and reconfigurable connecting elements that can be dynamically assembled and disassembled to adapt to different cargo configurations. This dynamic reconfigurability maintains versatility while using standardized components for ease of manufacture

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connecting elements can be positioned at different locations and configured in various arrangements to change the effective parameters of the load carrier system, enabling adaptability to different cargo sizes and shapes while using the same standardized components

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If modular detachable connections are implemented, then adaptability to different loads is improved, but connection strength and structural reliability may be reduced

Engineering Contradiction:
ImproveadaptabilityVSAvoidconnection strength
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connecting elements are pre-designed with optimized connection geometries and attachment points that ensure reliable and strong connections when assembled. This preliminary design of connection features maintains structural reliability while enabling detachable modular assembly for adaptability

Inventive Principle:
Principle #10Preliminary action

AI summary

The modular load carrier system (LS) comprises a bottom portion (1) and a main structure in which the floor elements (2) and strut elements (3) are mounted. The main structure includes several U-shaped connecting elements (6) which are connected detachably to assemble the carrier system, such that the outer and/or inner dimensions of the system are made variable. The main structure further comprises a cladding element (4). Two connecting elements each having a floor element, are detachably connected and oriented at right angles to each other.
