Solution Overview

Problem

Existing gap seals for movable dock levelers are not cost-effective, durable, or resistant to damage, and they fail to provide optimal thermal insulation due to air leakage, which affects building thermal performance.

Innovation Solution

A gap seal designed with a textile-like deformable surface element for both the holding and sealing sections, which can be easily cut to various dimensions, magnetically attached, and features a foldable omega-shaped cross-section for enhanced sealing and ease of cleaning, with an optional sealing strip for reduced wear and improved hygiene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If a generic gap seal with frame profile and sealing section is used, then the gap can be sealed, but the thermal insulation is significantly affected due to air flow through the gap

Engineering Contradiction:
Improvethermal insulationVSAvoidair flow through gap
Core Design Contradiction:
Loss of energyVSObject-affected harmful factors

Solution Approach 1:

The patent employs a flexible planar element (textile-like deformable surface) that can conform to the gap geometry and provide effective sealing. This flexible membrane approach allows the seal to adapt to the movable dock leveler's position changes while maintaining thermal insulation by blocking air flow through the gap.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If traditional gap seals are used, then sealing is provided, but they are not cost-effective and durable

Engineering Contradiction:
ImprovedurabilityVSAvoidcost-effectiveness
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent changes the material parameters by using a textile-like deformable surface instead of traditional rigid or semi-rigid sealing materials. This material substitution provides both improved durability through flexibility and resistance to damage, while also reducing manufacturing costs due to the simplicity of cutting and attaching the textile material.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The textile-like deformable surface can be easily replaced if damaged, and the simple construction allows for cost-effective replacement. The seal's design enables it to be cut from larger pieces of textile material, making it inexpensive to manufacture and replace when needed.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of manufacture

If the holding and sealing sections are made from separate components, then assembly is possible, but production is more complex and costly

Engineering Contradiction:
Improveproduction simplicityVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the holding section and sealing section into a single integrated planar element. The textile-like deformable surface serves dual functions: it provides structural support for mounting (holding function) and creates the sealing barrier (sealing function) through its foldable omega-shaped configuration. This eliminates the need for separate components and simplifies both manufacturing and assembly.

Inventive Principle:
Principle #5Merging (Combining)

4Strength

If the sealing section is made rigid, then structural stability is provided, but it cannot be easily cleaned and is susceptible to damage

Engineering Contradiction:
Improveresistance to damageVSAvoidease of cleaning
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent makes the sealing section dynamic and flexible rather than rigid. The textile-like deformable surface can bend and fold into an omega-shaped configuration, allowing it to be easily cleaned by flushing while maintaining structural integrity through its material properties. The flexibility provides resistance to damage from cleaning operations and environmental factors.

Inventive Principle:
Principle #15Dynamics
