Solution Overview

Problem

Existing workshop pit covers face challenges due to their significant weight when moving between open and closed positions, leading to deterioration of drive and guide means.

Innovation Solution

The design incorporates supporting elements arranged in strips with a guide device featuring internal and external bearing tracks, a double-bearing device for vertical storage, and a motor-driven system with flexible fabric elements to reduce weight and ensure smooth movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If supporting elements are arranged in a continuous train to cover the workshop pit, then the cover provides complete protection and structural integrity, but the weight of the cover increases significantly during horizontal movements

Engineering Contradiction:
Improvecover protection integrityVSAvoidcover weight during movement
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The cover is divided into multiple independent strips (first strip, second strip, etc.) that can move separately rather than as a single continuous structure. Each strip has its own supporting elements arranged in series, allowing the cover to maintain protection integrity while reducing the weight each drive mechanism must move and enabling vertical storage when not in use

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the cover is moved horizontally between open and closed positions, then the pit can be accessed or protected as needed, but the drive means and guide means suffer deterioration due to the significant weight

Engineering Contradiction:
Improvecover position flexibilityVSAvoiddrive means durability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The cover system transitions from a static continuous structure to a dynamic segmented system where strips can be positioned horizontally for operation/protection and vertically stored when not needed. This dynamic reconfiguration reduces the weight burden on drive means during movements and extends their lifespan

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cover strips can transition between horizontal positioning (for covering the pit) and vertical positioning (for storage). This addition of the vertical dimension allows the system to reduce wear on drive and guide means by minimizing horizontal movement weight burden when the cover is not actively protecting the pit

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If guide rails are arranged on the upper edges of the pit to support the cover, then the cover can be guided between positions, but the guide means deteriorates due to the continuous heavy load

Engineering Contradiction:
Improvecover guidance capabilityVSAvoidguide means service life
Core Design Contradiction:
Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The guide system is segmented to work with individual cover strips rather than supporting a continuous heavy train. Each strip can be guided independently, reducing the continuous load on guide rails and extending their service life while maintaining ease of operation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide rails work with dynamically positioned strips that can be stored vertically when not in use, reducing the continuous horizontal load that causes deterioration. The guide means only needs to support and guide strips during active operation, not continuously bear the full weight

Inventive Principle:
Principle #15Dynamics

4Stability of the object's composition

If supporting elements are interconnected in a continuous train, then the cover maintains structural integrity during movement, but the friction and wear on drive and guide components increases

Engineering Contradiction:
Improvecover structural integrityVSAvoiddrive means and guide means longevity
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The cover is segmented into multiple independent strips rather than a continuous train. Each strip maintains its own structural integrity through internally connected supporting elements, while the segmentation reduces overall friction and wear on drive and guide means by allowing independent movement and vertical storage capability

Inventive Principle:
Principle #1Segmentation
