Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If columns are stored in the cavity of the base frame during empty return transport, then space is utilized, but the columns are randomly oriented causing noise and handling difficulties

Engineering Contradiction:

Improvehandling of load carrierVSAvoidnoise during transport

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The base frame cavity is segmented into multiple storage compartments by introducing vertical dividers and horizontal support bars. These compartments guide columns to be stored in specific orientations rather than randomly, with each compartment accommodating columns in a defined direction. This segmentation resolves the contradiction by organizing columns to reduce noise while maintaining space utilization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Support bars and dividers are introduced as intermediary elements between the columns and the base frame cavity. These intermediaries hold columns in specific positions and orientations during transport, preventing random movement and noise generation. The intermediaries act as mediators that organize the stored columns without requiring complex active control mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If columns are stored randomly in the base cavity, then storage capacity is maximized, but directionality and organization are lost

Engineering Contradiction:

Improvenumber of columns storedVSAvoidorientation consistency of columns

Core Design Contradiction:

Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The storage compartments are designed with asymmetric features including vertical dividers of different heights and support bars positioned at specific locations. These asymmetric elements create defined spaces that accommodate columns in specific orientations, ensuring orientation consistency while maintaining high storage capacity. The asymmetry prevents columns from being stored in multiple random orientations within the same compartment.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The base frame structure is pre-configured with dividers and support bars during manufacturing to create organized storage compartments. This preliminary action ensures that when columns are loaded for empty return transport, they are guided into specific orientations from the beginning, maintaining organization and directionality throughout the transport process without requiring active management during transit.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the base frame has a large open space for column storage, then columns can be easily accessed, but noise is generated when run over uneven foundations

Engineering Contradiction:

Improveaccess to columnsVSAvoidnoise from column movement

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

Different regions of the base frame cavity are assigned different functions through local quality differentiation. Storage compartments are created with specific local characteristics including dividers and support bars in areas where columns are stored, while other areas maintain open space for accessibility. This local differentiation allows columns to be securely organized in specific zones while maintaining ease of access to the overall storage area.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The storage compartment structure uses a nested arrangement where vertical dividers and horizontal support bars are integrated within the base frame cavity. The dividers and support bars are nested between the columns and the frame walls, creating organized storage spaces that reduce column movement and noise while maintaining access. The nested structure allows columns to be stored in defined orientations without requiring a completely enclosed rigid container.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A load carrier comprising a rectangular base frame and a plurality of support bars and/or plate portions surround by a frame portion is provided. The support bars may be transverse or longitudinal. Wheels may be provided on a bottom portion of the base frame. Connecting pieces may be provided on the base frame, for example at corners of the base frame, for receiving columns during use of the load carrier. Substantially U-shaped members may be provided on the support bars for receiving the columns when the load carrier is not in use. The substantially U-shaped members may have an upwardly open channel having sides and a base.
