Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical locking systems face challenges in adapting to various door thicknesses, leading to increased complexity and costs due to the need for multiple inventory models and potential installation errors.
Innovation Solution
The introduction of a telescoping wire conduit that can be extended and locked to accommodate different door thicknesses, allowing for a single locking system model to be used across multiple door sizes by providing a flexible electrical connection between the outer and inner housings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different locking system models are provided for different door thicknesses, then adaptability to various door sizes is improved, but device complexity and inventory management complexity increase
Solution Approach 1:
The patent implements a universal locking system model that can accommodate multiple door thicknesses through a telescoping wire conduit. The conduit can be adjusted to different lengths and positions, allowing a single lock model to function across various door sizes (e.g., 1.375" to 2.5" thicknesses), thereby eliminating the need for multiple specialized models and simplifying inventory management.
Solution Approach 2:
The wire conduit is designed with dynamic adjustability, allowing it to be extended or retracted to different lengths and positions depending on the door thickness. This dynamic characteristic enables the locking system to adapt to various door configurations without requiring multiple fixed models, resolving the contradiction between adaptability and complexity.
2Manufacturing precision
If a fixed-length wire conduit is used, then manufacturing precision is improved, but adaptability to various door thicknesses deteriorates
Solution Approach 1:
The wire conduit incorporates a telescoping mechanism that allows it to be adjusted to different lengths and positions after manufacturing. This dynamic adjustment capability enables a single precision-manufactured conduit to serve multiple door thickness requirements, resolving the contradiction between manufacturing precision and adaptability.
Solution Approach 2:
The wire conduit is divided into adjustable segments or sections that can be extended or retracted to achieve the required length and positioning for different door thicknesses. This segmentation allows the conduit to maintain manufacturing precision while gaining adaptability through configuration adjustments.
3Adaptability or versatility
If multiple locking system models are maintained for different door sizes, then adaptability is improved, but installation error probability increases
Solution Approach 1:
By implementing a universal locking system model with an adjustable wire conduit, the patent reduces the number of different models that need to be selected and installed. This universality minimizes the opportunity for installation errors related to model selection and ensures consistent installation procedures across different door sizes, thereby improving reliability while maintaining adaptability.

AI summary
The locking system can have an outer housing mounted to an outside face of the door, and an inner housing mounted to an inside face of the door, a wire conduit mounted to one of the inner housing and the outer housing and extending across the door to the other one of the inner housing and the outer housing, the wire conduit having two telescoping members, and at least one wire extending inside the wire conduit and connected between a first locking system component housed in the outer housing and a second locking system component housed in the inner housing.
