Solution Overview

Problem

Existing container floor structures fail to effectively restrict the movement of various cargoes within a container, particularly those not adjacent to the inner wall, and often require customization, leading to high costs and inefficiencies.

Innovation Solution

A container floor assembly comprising a floor unit, a blocking member, and a limiting member, where the blocking member is supported on the floor unit, and the limiting member connects the blocking and floor units to restrict lateral movement, using a combination of plates and reinforcement ribs, with detachable limiting structures that can be reused across different cargo configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If shelves are used to restrict cargo movement, then cargo stability is improved, but device complexity and cost increase due to needing different shelves for different cargoes

Engineering Contradiction:

Improvecargo stabilityVSAvoidshelf configuration complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The blocking member with limiting structure is designed as a universal component that can restrict cargo movement in multiple directions and be positioned at various locations within the container. The same blocking member can serve different cargoes by adjusting its position and orientation, eliminating the need for cargo-specific shelves.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The limiting structure is divided into separable components: the blocking member and the floor unit with limiting hole. This segmentation allows the blocking member to be independently positioned and reconfigured for different cargo arrangements while maintaining the connection through the limiting member.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If buffering beams are arranged on the inner wall, then cargo protection from wall impact is improved, but cargo movement restriction capability deteriorates as it only applies to cargoes adjacent to the inner wall

Engineering Contradiction:

Improveprotection from wall impactVSAvoidapplicability to different cargo positions

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The limiting structure extends the protection concept from the wall dimension to the floor dimension. By placing the limiting hole in the floor unit rather than attaching beams to walls, the system can restrict cargo movement at any position within the container footprint, not just near walls.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The limiting member acts as an intermediary that connects the blocking member to the floor unit, transferring lateral forces from cargo to the floor structure. This mediator enables force transmission without requiring direct wall attachment.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If foamed material is used to prevent cargo collision, then cargo protection is improved, but cost increases due to non-reusability and it fails to restrict cargo movement

Engineering Contradiction:

Improveprotection from cargo collisionVSAvoidcargo movement restriction capability

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent replaces the passive foam material system with an active mechanical limiting structure. Instead of relying on deformable foam to absorb impact, the rigid blocking member with limiting structure actively prevents cargo from reaching collision positions through deterministic geometric constraints.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the protective mechanism from material-based (foam density, compression) to geometry-based (limiting hole dimensions, blocking member position). By adjusting geometric parameters rather than material properties, the system achieves both movement restriction and protection functions.

Inventive Principle:

Principle #35Parameter changes

4Ease of repair

If detachable limiting structures are used, then reusability and cost efficiency are improved, but connection reliability may deteriorate compared to fixed structures

Engineering Contradiction:

Improvereusability of limiting structureVSAvoidconnection reliability

Core Design Contradiction:

Ease of repairVSReliability

Solution Approach 1:

The limiting structure is pre-assembled as an integrated unit with the blocking member, ensuring proper alignment and connection integrity before deployment. The limiting hole and blocking member are designed with precise tolerances to maintain reliable connection upon reassembly after use.

Inventive Principle:

Principle #10Preliminary action
