Solution Overview

Problem

Existing securing devices for railings on construction sites are not versatile and can fall off, posing safety risks and structural issues, and there is a need for a more secure and easy-to-mount solution for both windows and doors.

Innovation Solution

A kit of parts comprising a securing device with a rectangular opening and a circular wall attachment, featuring protrusions and sectional grooves, made of recyclable materials, to securely hold railings in place using fastening holes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional securing device with long connections is used, then the railing can be disengaged and fall off, but the device becomes complex and difficult to install

Engineering Contradiction:
Improverailing securityVSAvoidsecuring device structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The securing device is divided into separate modular components: a securing device body with mounting holes, a railing component with receiving slots, and a wall attachment. This segmentation allows each component to be optimized independently while simplifying installation and improving reliability through precise fitting interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The railing is nested within the securing device structure, with the railing component fitting into the securing device body through complementary geometric shapes (rectangular opening with protrusions fitting into corresponding grooves). This nesting provides inherent mechanical interlocking that prevents disengagement without complex fastening mechanisms.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a versatile securing device with rectangular opening and multiple grooves is used, then the railing can be securely held for both windows and doors, but the manufacturing complexity increases

Engineering Contradiction:
Improveapplicability to windows and doorsVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The securing device is designed with a universal rectangular opening structure and multiple sectional grooves that can accommodate different railing configurations for both window and door applications. The standardized geometry allows the same device to serve multiple functions across different installation contexts without requiring custom manufacturing for each application.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device incorporates adjustable parameters through its multiple sectional grooves and protrusions, allowing the same basic structure to adapt to varying railing dimensions and installation requirements. By changing the engagement position within the available grooves, the device can accommodate different railing types while maintaining consistent manufacturing processes.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the railing is left open-ended during construction, then installation is simple, but it affects worker safety and construction quality

Engineering Contradiction:
Improveinstallation simplicityVSAvoidworker safety risks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The securing device is pre-configured with mounting holes and engagement features that allow the railing to be immediately secured to the wall surface during installation. This preliminary preparation of the securing mechanism ensures that the railing can be quickly fixed in place without complex assembly steps, thereby maintaining installation simplicity while eliminating safety risks from open-ended railings.

Inventive Principle:
Principle #10Preliminary action

AI summary

A kit of parts (100) for securing railings (112) in doors and windows on the construction site, are disclosed. The kit of parts (100) for securing railings (112), comprises: a securing device (102, 104, 106, 108, 110) and a circular wall attachment (116). The securing device (102, 104, 106, 108, 110) comprises a rectangular opening (102) for securing rails between a pair of first outer side walls and a pair of second outer side walls where each of said walls constitute a side of said rectangular opening (102). The first pair of outer side walls (104 and 106) include one or more protrusions at both the side walls (104 and 106). The circular wall attachment (116) having a circular base (118) for being attached to a wall surface (114), wherein the circular wall attachment (116) holds the railing in place on the wall surface (114) when in use. The circular base (118) includes a plurality of sectional grooves (120) for receiving and holding the railing (112) in place in the circular base (118).
