Window Securing Part with Resilient Lip and Blocking Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window constructions are vulnerable to unauthorized disassembly of glass sections, allowing burglars to remove and reassemble windows without leaving obvious signs of entry, due to inadequate securing mechanisms, particularly relying on easily removable glazing beads.
Innovation Solution
A glass securing part is designed with a resilient lip and blocking part that snaps into a groove in the casement, providing enhanced security by preventing disassembly, using a plastic glass block with inclined lips and a steel blocking part to resist forces and prevent access, without adding significant production costs or complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If only an outside applied glazing bead is used to hold the window section in place, then the construction is simple and easy to manufacture, but the window section can be easily disassembled and removed
Solution Approach 1:
The glass block is nested within the casement groove, with the resilient lip inserting into the groove to create a secured position. The blocking part is positioned behind the glass block, creating a nested arrangement where components are embedded within each other to prevent removal while maintaining a compact structure.
Solution Approach 2:
The blocking part extends from the rear of the glass block into the groove, adding a dimensional element that prevents disassembly from the front. This creates a multi-dimensional securing mechanism where the block is restrained both by the groove engagement and the blocking part extending into the groove space.
2Reliability
If silicone glue is applied to reinforce protection against disassembly, then security is improved, but additional cost and environmental problems are introduced
Solution Approach 1:
The chemical bonding mechanism of silicone glue is replaced with a mechanical securing system consisting of the resilient lip engaging with the groove and the blocking part preventing disassembly. This substitution eliminates the need for adhesives while providing equivalent or superior security through pure mechanical means.
Solution Approach 2:
The mechanical securing system uses simple, inexpensive components that can be easily manufactured and installed without the need for expensive adhesive materials. The resilient lip and blocking part are designed as durable but low-cost elements that provide effective security.
3Reliability
If a resilient lip and blocking part are added to secure the glass block in the groove, then security against disassembly is improved, but device complexity increases
Solution Approach 1:
The glass block serves multiple functions: it acts as the window glass support, provides structural spacing, engages with the groove through the resilient lip for securing, and works with the blocking part to prevent disassembly. This multi-functionality reduces the need for separate dedicated securing components.
Solution Approach 2:
The securing function is merged into the glass block assembly itself, with the resilient lip and blocking part becoming integral components of the glass block unit. This integration eliminates the need for separate securing mechanisms and reduces overall system complexity.

AI summary
A device for assembling in a window section (1) and in its casement (2) and where this device is a complete glass securing part (11) which is constructed of a glass block (10) and a blocking part 12. The glass securing part (11) and its glass block (10) has resilient lips (4) which engage in grooves (3) of the casement and which, when these lips is snapping in the groove, prevents that the glass securing part can be disassembled. Since the blocking part (12) extends upwards and in front of the lower part of the window section the window section cannot be removed from the casement. With the present device is consequently a protection against simple burglaries obtained, which in some cases are difficult to prove.
