Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional mortarless retaining walls lack the ability to create setbacks and have limited arrangement options, with blocks typically requiring coplanar alignment and lacking an attractive finished appearance, necessitating additional installation steps and limited contouring on the bottom surface for structural integrity.

Innovation Solution

Retaining wall blocks with spaced-apart front and rear sections interconnected by side sections defining a through-cavity, featuring protuberances on the top face and a groove on the bottom face, allowing for staggered stacking and textured front faces with simulated dress joints, enabling high-speed production and aesthetically pleasing designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional mortarless retaining wall blocks are used with coplanar arrangement, then assembly is simplified and construction speed increases, but setbacks cannot be created and arrangement options are limited

Engineering Contradiction:

Improveassembly speedVSAvoidarrangement options

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The block is divided into distinct functional zones: a first course-receiving surface with a groove for setbacks, and a second course-providing surface for the next layer. This segmentation allows different portions of the block to serve different purposes, enabling both rapid assembly and setback creation simultaneously.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention introduces setback capability by utilizing the lateral dimension through the groove feature, rather than requiring all blocks to be coplanar. This dimensional change allows courses to be offset horizontally while maintaining interconnection, expanding arrangement options without sacrificing assembly efficiency.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If conventional blocks require coplanar alignment for interconnection, then structural stability is maintained, but aesthetic appeal is reduced and additional installation steps are needed

Engineering Contradiction:

Improvestructural stabilityVSAvoidinstallation simplicity

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The groove and protrusion features are designed to automatically guide block placement and self-align courses during assembly. The interlocking mechanism inherently maintains structural stability while the self-aligning nature eliminates the need for additional installation steps or specialized skills.

Inventive Principle:

Principle #25Self-service

3Ease of manufacture

If conventional blocks lack groove features on bottom surfaces, then manufacturing is simpler, but staggered stacking and setback capability are not achieved

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidstacking arrangements

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The groove is pre-formed in the bottom surface of each block during manufacturing, preparing the block in advance for staggered stacking and setback arrangements. This preliminary action integrates the setback capability into the basic block structure without adding complex assembly procedures.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If blocks are arranged in thick courses with random placement, then setback capability is achieved, but course height is dictated by vertical blocks and true random arrangement is not possible

Engineering Contradiction:

Improvesetback capabilityVSAvoidarrangement constraints

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The groove feature serves multiple functions: it enables setbacks, facilitates staggered stacking, and allows various stacking patterns including running bond and random arrangements. This multi-functionality provides true versatility without the constraints of thick courses or vertical block requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A retaining wall block has spaced-apart front and rear sections interconnected by two laterally spaced-apart side sections that jointly define a through-cavity that extends through the block from a top face thereof to a bottom face thereof. Two or more protuberances protrude outwardly from the top face of the front section frontwardly of the through-cavity. A groove extends laterally in the bottom face of the front section frontwardly of the through-cavity. The groove is located and dimensioned relative to the protuberances so that two blocks can be stacked one atop another in staggered relation with one or more protuberances of the lower block engaged with one but not both of a front wall and a rear wall of the groove of the upper block and the upper block setback with respect to the lower block.
