Adjustable Inspection Hatch With Modular Support Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard fixed dimensions of inspection hatches result in high delivery times and production costs for customized hatches, as manufacturers must adapt to specific customer requests.
Innovation Solution
An inspection hatch design featuring a modular outer framework with L-shaped support section bars and a rotary inner door, allowing for customizable dimensions through adjustable coupling sections and locking mechanisms, enabling users to set desired dimensions and assemble the inner closing panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard fixed dimensions are used for inspection hatches, then manufacturing cost and delivery time are reduced, but adaptability to different customer requirements deteriorates
Solution Approach 1:
The outer framework is divided into multiple modular support section bars that can be selectively assembled. Each support section bar is a standardized component that can be combined in different quantities and configurations to create inspection hatches of various dimensions, allowing customization without requiring entirely new manufacturing processes.
Solution Approach 2:
The standardized support section bars serve multiple functions: they provide structural support, define the dimensions of the inspection hatch, and can be assembled in various configurations to meet different customer requirements. This universal component design allows a single standardized part to fulfill multiple customization needs.
2Adaptability or versatility
If standard fixed dimensions are used for inspection hatches, then manufacturing simplicity is maintained, but adaptability to different customer requirements deteriorates
Solution Approach 1:
The framework is segmented into standardized support section bars that can be independently manufactured and then assembled. This segmentation creates a modular system where complexity is distributed across identical components rather than concentrated in custom-designed parts, making the overall system more manageable despite its adaptability.
Solution Approach 2:
The inspection hatch design transitions from a fixed, static structure to a dynamic, reconfigurable system. The standardized support section bars can be selectively assembled and disassembled to change the dimensions and configuration of the inspection hatch, providing dynamic adaptability while maintaining structural integrity through consistent connection mechanisms.

AI summary
An inspection hatch has an inner door (11), which extends inside an outer framework (2) with a quadrilateral shape, is movable, relative to the outer framework (2), between an opening position and a closing position to open and close the inspection hatch, and is provided with an outer frame (12) and with an inner closing panel; the outer framework (2) and the outer frame (12) being each defined by at least two respective support section bars (7, 18), which are coupled to one another in a sliding manner, so as to selectively control the size of the outer framework (2) and of the outer frame (12) in at least one direction (4, 6).
