Solution Overview

Problem

Existing sliding door systems with motor-driven carriages and sensors face issues with sensor placement, aesthetics, and vulnerability to damage, as sensors are typically placed externally and require separate housings with openings for wiring, leading to unfavorable housing structures and increased risk of damage.

Innovation Solution

A sliding door system with a base body having a partially closed housing that accommodates sensor units internally, allowing for flexible and protected sensor placement, pre-assembly as a module, and adjustable positioning within the housing, using a sensor disk for electromagnetic wave reception and a profile element for easy attachment and adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If sensors are placed on the outside of the housing, then sensors can be easily accessed and installed, but the housing structure becomes unfavorable and sensors are exposed to damage

Engineering Contradiction:
Improvesensor installation easeVSAvoidsensor protection
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The sensor unit is integrated within the housing structure, with the sensor recessed into the housing body and protected by a protective cover. This nesting approach allows the sensor to be shielded from external damage while remaining accessible for installation and maintenance, resolving the contradiction between ease of installation and sensor protection.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If sensors are placed on the housing, then sensor installation is straightforward, but the housing requires openings for wiring and creates visual unattractiveness

Engineering Contradiction:
Improvesensor placement simplicityVSAvoidhousing aesthetic
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The sensor unit is merged with the housing structure, where the sensor is recessed into the housing and the protective cover integrates with the housing exterior. This combination eliminates the need for separate sensor housings and wiring openings, simplifying the overall structure while maintaining aesthetic appearance and ease of installation.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If sensors are exposed on the housing, then wiring access is easier, but sensors are vulnerable to unwanted damage

Engineering Contradiction:
Improvewiring accessVSAvoidsensor damage risk
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The sensor is nested within the housing with a protective cover that shields the sensor from external damage. The protective cover includes integrated wiring access features, allowing wires to be routed through or alongside the cover without exposing the sensor itself, thus reducing damage risk while maintaining wiring accessibility.

Inventive Principle:
Principle #7Nested doll (Nesting)
