Solution Overview

Problem

Conventional methods for installing elevator car lining panels are cumbersome and do not efficiently address the need for rapid and easy installation without significantly increasing the weight of the panels.

Innovation Solution

The elevator car lining panels feature a first connection portion for connecting with adjacent panels, incorporating a fixing structure that allows for secure attachment to structural panels, utilizing a clipping mechanism and hidden fixing elements to facilitate faster and easier installation while maintaining aesthetic and safety standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional methods are used to install elevator car lining panels, then the installation process is simple, but the installation speed is slow and the process is cumbersome

Engineering Contradiction:
Improveinstallation speedVSAvoidinstallation process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The lining panel is divided into multiple segments with connection portions at the edges. Each segment can be independently installed and connected to adjacent segments through the connection portions, enabling faster modular installation while maintaining structural integrity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection portions are pre-formed as integral parts of the lining panel during manufacturing. This preliminary preparation of connection structures eliminates the need for on-site assembly operations, significantly speeding up the installation process without adding complexity

Inventive Principle:
Principle #10Preliminary action

2Ease of repair

If fixing elements are made visible and accessible for easy maintenance, then the ease of repair is improved, but the safety and aesthetic standards are compromised

Engineering Contradiction:
Improveaccessibility of fixing elementsVSAvoidsafety hazards from visible fixing elements
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The connection portions serve as intermediaries that hide the fixing elements within their structure. The fixing elements are embedded in the connection portions rather than being directly exposed, eliminating safety hazards while maintaining aesthetic standards. Maintenance personnel can access these hidden fixing elements through the connection portions when repair is needed

Inventive Principle:
Principle #24Intermediary (Mediator)
