Dock Seal Segmentation and Nesting for Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dock weather barriers face challenges in providing effective sealing and minimizing wear, particularly at the intersections of side seal members and header structures, which can interfere with vehicle operations and lead to premature wear, while also consuming significant wall space and being susceptible to damage from vehicles.
Innovation Solution
The weather barrier apparatus features a horizontally elongate upper seal member and vertically elongate side seal members with strategically designed openings and hook-style rear edge seals, allowing the upper seal member to pass through the side seal members without displacement, and includes a side support member that deflects to seal effectively against vehicles of varying sizes and shapes, reducing wear and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dock seal side members are compressed to form a seal, then sealing quality is improved, but the side members are displaced into the opening and interfere with forklift and operator operations
Solution Approach 1:
The side members are divided into multiple independently movable segments that can deflect locally when compressed by a vehicle, rather than moving as a single unit. This segmentation allows the seal to contact the vehicle while limiting displacement into the opening, maintaining both sealing quality and operational access.
Solution Approach 2:
The side members are designed with dynamic deflection capabilities, allowing them to move elastically when compressed by a vehicle. This dynamic response enables the seal to adapt to vehicle positions while the segmented structure prevents excessive displacement that would block forklift and operator access.
2Strength
If dock shelter side members are mounted well outside the building wall to prevent impact damage, then protection from vehicle impact is improved, but wall space consumption increases
Solution Approach 1:
The side members are nested within or integrated with the building wall structure, utilizing the wall space efficiently. This nesting approach allows the side members to be positioned close to the wall while maintaining impact resistance, reducing the overall wall space consumption compared to traditional outward-mounted configurations.
Solution Approach 2:
The side members incorporate flexible, resilient materials that can absorb impact forces without requiring excessive distance from the building wall. This flexibility allows the side members to deflect under impact while maintaining protection, reducing the space needed beyond the wall while preserving impact resistance.
3Reliability
If header structure includes a weighted fabric curtain to form an environmental barrier, then sealing effectiveness is improved, but the structure becomes more complex and susceptible to damage
Solution Approach 1:
The weighted fabric curtain is extracted from the main header structure and implemented as a separate, removable component. This extraction simplifies the primary header structure while maintaining sealing effectiveness through the standalone curtain, reducing overall complexity and susceptibility to damage.
Solution Approach 2:
The header structure utilizes adjustable parameters such as curtain weight, length, and tension to optimize sealing effectiveness without increasing structural complexity. By varying these parameters rather than adding complex mechanical components, the system maintains reliability while minimizing device complexity.

AI summary
Example weather barrier apparatuses for sealing or sheltering vehicles at loading docks are disclosed herein. An example apparatus includes a first seal to be engaged by a vehicle as the vehicle moves between a departed position and a parked position relative to the first seal. The first seal has a penetration portion movable between a relaxed condition when the vehicle releases the first seal and an activated condition when the vehicle engages the first seal. A second seal is coupled adjacent the first seal. The second seal has an opening to be positioned adjacent the penetration portion of the first seal such that at least a portion of the penetration portion extends across at least a portion of the opening when the first seal is in the relaxed condition, and the opening of the second seal receives at least the penetration portion of the first seal when the first seal is in the activated condition.
