Solution Overview

Problem

The manipulation of existing gateways for display panels, particularly in public places, is cumbersome and requires significant effort due to their size and weight, making maintenance operations like replacing posters labor-intensive.

Innovation Solution

The proposed assembly includes a display panel with a gateway featuring low protection members at a height of 40-70 cm and a high protection member at 100-120 cm, along with a gantry system that can automatically deploy and lock into position, reducing the effort required for handling and positioning the gateway.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional gateways with full high protection members are used, then safety protection is improved, but the size and weight increase making manipulation difficult

Engineering Contradiction:
Improvesafety protectionVSAvoidmanipulation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The gateway barriers are segmented into two distinct parts: low protection members (40-70 cm height) that are always present, and high protection members (100-120 cm height) that can be selectively deployed. This segmentation allows the gateway to provide necessary safety protection while reducing overall size and weight for easier manipulation during maintenance operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The high protection members are designed to be movable rather than fixed, allowing them to be deployed when needed for safety and retracted when not needed. This dynamic configuration enables the gateway to adapt its protection level based on operational requirements, maintaining safety while improving ease of operation during maintenance tasks.

Inventive Principle:
Principle #15Dynamics

2Reliability

If full high protection members are installed on both barriers, then safety is improved, but the gateway becomes too heavy and large for easy handling

Engineering Contradiction:
ImprovesafetyVSAvoidgateway weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The protection system is divided into permanent low protection members and optional high protection members. By separating these functions, the gateway maintains adequate safety protection through the low members while avoiding the excessive weight and size that would result from permanently installing high protection members on both barriers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

High protection members are deployed selectively at specific locations (first barrier or second barrier) based on the maintenance task requirements, rather than uniformly on both barriers. This local quality approach ensures safety where needed while minimizing overall gateway weight and size for easier handling.

Inventive Principle:
Principle #3Local quality

3Reliability

If the gateway includes complete high protection members on both sides, then protection coverage is improved, but the device complexity and handling difficulty increase

Engineering Contradiction:
Improveprotection coverageVSAvoidgateway structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The gateway structure is segmented into simple permanent low protection members and optional high protection members that can be selectively deployed. This segmentation reduces the permanent structural complexity while maintaining comprehensive protection coverage when needed, as the high members are only added temporarily for specific maintenance operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The selective deployability of high protection members reduces permanent device complexity. The gateway structure remains simple and easy to handle in its basic configuration, with the capability to add protection coverage dynamically when required, rather than requiring a permanently complex structure with all protection elements always present.

Inventive Principle:
Principle #15Dynamics

AI summary

The panel has a rigid metal structure (2) comprising a glazed posting face (5) for displaying a posting. Support jambs (10) are mounted to move on the structure between a utilization position in which the jambs are adapted to receive a horizontal footbridge (11) for allowing an operator (12) to access the structure and a retracted position in which the jambs are retracted in the structure. The support jambs are suspended to the structure. The structure has vertical tubular guides, each comprising horizontal lower and upper cross-pieces (7, 9) and vertical lateral uprights (8).
