Lateral Display Press Seal for Confined Space Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing press seals with display elements are limited in accessibility, as the display region is typically exposed only in a top view, making it difficult to inspect the tensioned state, especially in confined spaces.
Innovation Solution
A press seal design with a display region exposed laterally, allowing the display element to be visible perpendicular to the longitudinal axis of the tensioning bolt, enabling easier inspection without the need to view from directly above, and incorporating a deformation element that widens asymmetrically to enhance visibility and space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display region is arranged at the top view (axial direction), then the display element can be read out along the longitudinal axis of the tensioning bolt, but the accessibility is limited and inspection is difficult in confined spaces
Solution Approach 1:
The display region is repositioned from the axial direction (top view) to a lateral direction perpendicular to the longitudinal axis of the tensioning bolt. This dimensional change allows inspection from the side rather than requiring top-down access, significantly improving accessibility in confined spaces where the line is led through walls close to the floor or under limited space conditions.
2Ease of operation
If the display region is exposed laterally perpendicular to the longitudinal axis, then accessibility and inspection ease are improved, but the structural arrangement becomes more complex
Solution Approach 1:
The press body is divided into a first press body part and a second press body part that are movable with respect to each other in the axial direction. The display element is arranged between these parts, and the display region is formed on the lateral surface of one of the press body parts. This segmentation allows the display to be accessed laterally while maintaining the functional integrity of the press seal.
Solution Approach 2:
A deformation element is introduced that widens asymmetrically when compressed by the tensioning bolt. This asymmetric deformation enhances the visibility of the display element in the lateral display region while efficiently using the available space, and the press body is adapted to accommodate this asymmetric widening pattern.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easier assembly and inspection of the press seal in restricted spaces by providing lateral access to the display region, ensuring the tensioned state can be verified without kneeling, while maintaining effective sealing and preventing material damage.
Implementation Method 1
the press body is pressed against the elastomer body by tensioning the tensioning bolt, so that the elastomer body is tensioned and contacts the line sealingly
Implementation Method 2
the press body comprises a first and a second press body part, the press body parts being movable with respect to each other in an axial direction parallel to the longitudinal axis of the tensioning bolt, the relative movement being supported by a deformation element

AI summary
A press seal (1) with an elastomer body (2) includes a press body (9, 10) which can be pressed against the elastomer body (2) by tightening a clamping bolt (4) and as a result, the elastomer body (2) is sealed on a line. The pressing body (9, 10) includes a display element (11) which can be visible in a display range (18) when a clamping state of the elastomer body (2) is reached. The pressing body (9, 10) includes a first (13) and a second press body part (14) movably mounted with respect to each other in an axial direction (3) parallel to the longitudinal axis (7) of the clamping bolt (4) such that when the elastomer body (2) is in the clamped state, it adopts a relative position modified with respect to the non-clamped initial state, which can be read on the display element (11).
