Solution Overview

Problem

Existing methods for manufacturing resilient rail support block assemblies for railway tracks are inefficient and require additional adhesive steps, increasing complexity and potential for errors during installation.

Innovation Solution

A manufacturing method involving a prefabricated resilient member with an outer and inner tray, where the resilient intermediate structure is bonded to both, allowing the concrete block to adhere directly to the inner tray during hardening, eliminating the need for separate adhesives and simplifying the installation process by integrating transverse tie bars and enhancing anchoring with specific tray designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate adhesive step is used to fix the block to the resilient member, then the block can be securely attached, but the manufacturing process becomes more complex and less efficient

Engineering Contradiction:
Improveblock attachment reliabilityVSAvoidmanufacturing process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the block attachment function with the resilient member structure itself. The resilient member is designed with an integrated bonding interface that directly bonds to the block during the concrete pouring process, eliminating the need for separate adhesive application steps and tools.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The resilient member is pre-fabricated with built-in bonding characteristics before the block is assembled. The bonding surface and adhesive properties are prepared in advance during resilient member manufacturing, so no additional adhesive preparation is needed at the assembly stage.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If multiple separate steps are used for assembly, then each step can be optimized, but the overall installation time and complexity increase

Engineering Contradiction:
Improveassembly precisionVSAvoidmanufacturing efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent merges multiple assembly operations into a single integrated process. The resilient member, block, and anchoring elements are combined into one assembly operation where the concrete is poured directly over the pre-assembled resilient member and block combination, achieving both precision and efficiency.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If additional adhesives and materials are used, then the bonding strength is improved, but the material cost and potential for errors increase

Engineering Contradiction:
Improvebonding strengthVSAvoidmaterial quantity
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The resilient member is designed to be self-sufficient with built-in bonding capabilities. The material itself provides the necessary adhesive properties through its composition and structure, eliminating the need for additional adhesive materials and reducing the quantity of substances required.

Inventive Principle:
Principle #25Self-service

AI summary

A method for manufacturing a resilient rail support block assembly (1), which assembly is adapted to be mounted embedded in or mounted on a railway substructure and which assembly comprises a prefabricated resilient member (10) as well as a moulded block (20) of a suitable mouldable material, preferably of concrete, having a top, a bottom and peripheral wall, said block being adapted for fastening one or more rails on the top of said block. The prefabricated resilient member (10) has an outer tray (12) and inner tray (13) arranged within said outer tray, and comprises a resilient intermediate structure (15) arranged between said outer and inner trays (12, 13). The prefabricated resilient member (10) is used to form a part of the block mould, so that one or more additional mould members combined with said prefabricated resilient member delimit the mould for the block, the mouldable material being introduced into said block mould and thereby adhering directly to the inner tray (13) of the prefabricated resilient member (10).
