Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional masonry wall construction requires the use of mortar, which can be time-consuming and may not provide a structurally sound or aesthetically pleasing solution, especially in modular block systems where alignment and load distribution are critical.
Innovation Solution
A modular block system comprising inner and outer structural members with retaining grooves and spanning members that allow for slidable engagement, eliminating the need for mortar by using retaining features to align and secure block modules vertically and laterally, while incorporating insulation for thermal efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If mortar is used to hold masonry units together, then structural stability is improved, but construction time increases and aesthetic quality deteriorates
Solution Approach 1:
The patent removes mortar from the construction system entirely, replacing it with a mechanical interlocking mechanism consisting of retaining grooves and spanning members. This extraction of the problematic material (mortar) allows for faster assembly while maintaining structural integrity through the groove-spanner engagement system.
Solution Approach 2:
The patent replaces the chemical bonding mechanism of mortar with a mechanical interlocking system. The retaining grooves on structural members engage with spanning members to create a purely mechanical connection, eliminating the need for adhesive materials and reducing construction time while maintaining stability.
2Strength
If mortar is used to secure block modules, then structural soundness is improved, but aesthetic quality deteriorates
Solution Approach 1:
The patent eliminates mortar from the system, removing the source of aesthetic defects such as visible joints and uneven surfaces. The mechanical interlocking system provides structural soundness without the visual imperfections associated with mortar application, resulting in cleaner, more aesthetically pleasing block walls.
Solution Approach 2:
The mechanical interlocking mechanism replaces mortar-based bonding, providing structural strength through precise geometric engagement rather than adhesive materials. This substitution eliminates the need for mortar joints, creating a smoother, more aesthetically pleasing surface while maintaining structural integrity.
3Ease of operation
If traditional masonry stacking is used, then ease of assembly is improved, but alignment precision deteriorates
Solution Approach 1:
The patent replaces simple stacking with a mechanical interlocking system that inherently provides alignment precision. The retaining grooves and spanning members are designed with specific geometries that guide and constrain the assembly process, ensuring accurate alignment while maintaining ease of operation through the intuitive groove-spanner engagement mechanism.
4Strength
If mortar-based construction is used, then load distribution is improved, but device complexity increases
Solution Approach 1:
The patent removes mortar from the load distribution system, replacing it with a mechanical interlocking mechanism. This simplification eliminates the complexity of mortar application, mixing, and curing processes while maintaining load distribution capabilities through the engineered groove-spanner engagement system.

AI summary
A modular masonry system includes a plurality of masonry modules each having inner and outer structural members. Top and bottom spanning members extend the length of the inner and outer structural members and are retained within respective upper and lower retaining grooves of the inner and outer structural members. The top spanning member includes a second retaining feature that cooperates with a first retaining feature of the bottom spanning member of an adjacent masonry module. An insulation member is disposed within an interior volume defined between the inner and outer structural members and the top and bottom spanning members. The first retaining feature of each bottom spanning member slidably engages the second retaining feature of at least one vertically adjacent top spanning member. The engagement of the first and second retaining features aligns and secures the engaged masonry modules without the use of mortar.
