Flush Sliding Window Lock Rotor for Transparent Showcase Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window locking devices for luxury stores are either expensive and aesthetically unsuitable due to bulky protrusions or unattractive and costly, failing to provide a balance between aesthetics, transparency, and affordability for sliding windows.
Innovation Solution
A sliding rotor lock mounted directly in a moving part of the sabot or end piece, with a bolt mechanism that engages in an opening of the rear shoe, featuring a flat profile for minimal visibility, elastic return means, and helical guiding for ergonomic operation, allowing secure and aesthetic locking without compromising transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a mechanical locking device is used, then the cost is reduced, but the aesthetic appearance and transparency are compromised due to visible protrusions
Solution Approach 1:
The locking mechanism is moved from a protruding cylindrical design into the plane of the shoe, utilizing the thickness dimension of the shoe to house the rotor and bolt mechanism. This allows the lock to be flush with the shoe surface when locked, eliminating the stepped protuberance while maintaining mechanical functionality.
Solution Approach 2:
The rotor and bolt mechanism are nested within the shoe structure itself. The rotor is mounted in the front shoe, and the bolt extends through the shoe thickness to engage with the rear shoe, effectively hiding the locking components within the existing structural boundaries rather than adding external protrusions.
2Reliability
If a bulky locking device is used to ensure security, then the locking reliability is improved, but the transparency and refined shape are compromised
Solution Approach 1:
The locking action occurs within the thickness dimension of the shoe rather than projecting outward. The bolt travels through the shoe's thickness to engage the rear shoe, maintaining security through proper engagement depth while keeping the external profile flush and refined.
Solution Approach 2:
The shoe structure is designed with localized features (opening in the rear shoe, rotor mounting in the front shoe) that enable reliable locking engagement without requiring a bulky overall structure. The locking components are precisely positioned to achieve secure engagement with minimal external projection.
3Shape
If a lock rotor is mounted in the shoe, then the aesthetic appearance is improved, but the device complexity increases
Solution Approach 1:
The shoe structure serves multiple functions: it provides structural support for the window, guides the sliding motion, and houses the locking mechanism. By integrating the rotor mounting and bolt engagement features into the existing shoe design, the patent avoids adding separate complex locking assemblies while achieving aesthetic flush mounting.
