Solution Overview

Problem

Existing lifting tables in food and pharmaceutical manufacturing have hard-to-reach areas that are difficult to clean and disinfect due to limited penetration of cleaning fluids, making the processes time-consuming.

Innovation Solution

A lifting table design with two side members along its sides, spaced 1-8 mm apart, forming an anti-squeezing mechanism that allows cleaning foam to penetrate into the gap, combined with a switch element to prevent table displacement, and features like slots and apertures for enhanced cleaning access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the table top includes corners and hard-to-reach areas, then the lifting table can maintain structural integrity and support, but the cleaning process becomes time-consuming and cleaning fluid penetration is limited

Engineering Contradiction:
Improvestructural integrityVSAvoidcleaning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The side members are segmented with gaps between them, creating discrete openings that allow cleaning fluid to penetrate into previously inaccessible areas. The side members are divided into sections rather than forming continuous barriers, enabling cleaning access while maintaining structural support function.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the side members are fixed in position to ensure safety, then structural stability is maintained, but cleaning access to blind areas is blocked

Engineering Contradiction:
Improvestructural stabilityVSAvoidcleaning access
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The side members transition from a fixed to a movable configuration, allowing the system to adapt between operational modes. During normal operation, side members provide structural stability; during cleaning operations, they can be moved to provide access while maintaining controlled stability through the switch element safety mechanism.

Inventive Principle:
Principle #15Dynamics

3Reliability

If cleaning foam is applied to hard-to-reach areas, then disinfection effectiveness improves, but the foam has limited capability to penetrate into corners

Engineering Contradiction:
Improvedisinfection effectivenessVSAvoidcleaning fluid penetration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The continuous side member structure is segmented into separate sections with gaps between them. This segmentation creates direct pathways for cleaning foam penetration into areas that would otherwise be blocked, allowing disinfection fluid to reach previously inaccessible corners and blind areas without requiring complex delivery mechanisms.

Inventive Principle:
Principle #1Segmentation
