Solution Overview

Problem

Existing protective casings for automatic door automation components are bulky, limiting operator space and complicating maintenance and repair processes due to their extensive length and instability when opened.

Innovation Solution

A protective casing with a support bracket and a lid that can be manually moved between a closed position, a release position, and an opening position, allowing operators to choose whether to remove the lid for maintenance or keep it stable for operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the protective casing extends along the entire length of the automatic door to provide comprehensive protection, then the protection effectiveness is improved, but the device bulkiness increases and operator workspace is reduced

Engineering Contradiction:
Improveprotection effectivenessVSAvoiddevice bulkiness
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The protective casing is divided into multiple separate casings, each protecting a specific automation component (motor, sensor, control system) rather than covering the entire door length. This segmentation reduces the volume of any single protective casing while maintaining comprehensive protection across all components.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the lid is hinged to the support bracket to allow easy opening, then the ease of operation is improved, but the stability of the lid during operation deteriorates

Engineering Contradiction:
Improveease of lid openingVSAvoidlid stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The lid connection system allows dynamic adaptation: it can be hinged for easy opening during maintenance, or interlocked for stable protection during normal operation. This dynamic switching between connection modes resolves the contradiction between ease of operation and stability.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If the lid is interlocked to the support bracket to improve stability, then the stability is improved, but the ease of repair deteriorates due to removal complexity

Engineering Contradiction:
Improvelid stabilityVSAvoidease of lid removal
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The connection system dynamically switches between interlocked mode for stable protection during operation and hinged mode for easy removal during maintenance. This allows the same lid to provide both stability and ease of repair at different operational stages.

Inventive Principle:
Principle #15Dynamics

4Ease of repair

If the protective casing is designed to be removable for maintenance, then the ease of repair is improved, but the protection effectiveness deteriorates due to potential gaps

Engineering Contradiction:
Improveease of component accessVSAvoidprotection effectiveness
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The protective system is segmented into removable lid and support bracket components, allowing the lid to be detached for maintenance while the support bracket remains fixed and continues providing structural protection. This segmentation enables both ease of repair and maintained protection effectiveness.

Inventive Principle:
Principle #1Segmentation
