Solution Overview

Problem

Existing access control devices require multiple holes or openings in barriers for data and power transmission, which compromises durability, ease of installation, and fire safety ratings.

Innovation Solution

An access control device utilizing a multi-core cable within a fixing member to transmit data and power signals between locking and user interface components on opposite sides of a moveable barrier, reducing the need for additional holes and enhancing durability and installation ease.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate holes are made in the barrier for data and power transmission, then data and power can be transmitted between components, but the durability and fire safety rating of the barrier are compromised

Engineering Contradiction:

Improvebarrier durability and fire safetyVSAvoidnumber of holes in barrier

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate holes (one for data cable, one for power cable) into a single hole that accommodates both data and power transmission. The fixing member integrates multiple functions: it mechanically secures components to the barrier while simultaneously providing electrical connections for both data signals and power supply through its conductive structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fixing member serves multiple functions: it acts as a mechanical fastener to secure the locking and user interface components, serves as a structural support element, and functions as an electrical conductor for both data transmission and power supply. This multi-functionality eliminates the need for separate dedicated holes for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If multiple separate holes are made in the barrier for data and power transmission, then data and power can be transmitted between components, but the ease of installation is reduced

Engineering Contradiction:

Improveinstallation simplicityVSAvoidnumber of holes in barrier

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines multiple separate holes (one for data cable, one for power cable) into a single hole that accommodates both data and power transmission. The fixing member integrates multiple functions: it mechanically secures components to the barrier while simultaneously providing electrical connections for both data signals and power supply through its conductive structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fixing member is pre-configured with integrated data and power transmission capabilities before installation. The conductive structure is built into the fixing member itself, so that when the fixing member is installed through a single hole, both data and power connections are automatically established without requiring separate routing or connection steps.
