L-Shaped Insert Element for Drainage Cover Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yard drains made of composite materials face issues with air inclusions and bumps at the edge of recesses formed during casting, leading to compromised locking security and optical defects.
Innovation Solution
An insert element with an L-shaped cross-section, featuring a depression, collar, and anchor elements is used, which is positioned in a mold before casting to create a secure locking mechanism for the cover element, eliminating the need for slides and reducing air pocket formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If slides or permanent formwork are used to form recesses during casting, then the locking device receptacles can be formed, but air inclusions and bumps occur at the upper edge of the recesses, deteriorating locking security and creating optical defects
Solution Approach 1:
The locking device receptacle is divided into two parts: a recess formed in the base body and a separate insert element that is positioned in the mold before casting. This segmentation allows the insert element to provide a precise, bump-free upper edge for the receptacle, eliminating the air inclusion problems associated with forming the entire receptacle using slides or permanent formwork.
Solution Approach 2:
The insert element is positioned in the mold before the casting process begins. This preliminary action ensures that the insert element is already in place to form the upper edge of the recess receptacle, preventing air inclusions and bumps from occurring during the casting process while maintaining high locking security.
2Manufacturing precision
If slides or permanent formwork are used to form recesses, then the locking device receptacles can be created, but bumps form on the edge which represent optical defects
Solution Approach 1:
By segmenting the receptacle into a recess in the base body and a separate insert element, the insert element can provide a perfectly flat upper edge without bumps. This eliminates optical defects while the insert element itself remains a simple component that is easily positioned in the mold before casting.
Solution Approach 2:
The insert element acts as an intermediary component between the base body and the locking device. It provides the precise, bump-free upper edge for the recess receptacle, eliminating optical defects without complicating the overall manufacturing process, as the insert element is simply positioned in the mold before casting.
3Reliability
If the insert element is used to form the locking device receptacle, then locking security is improved, but the device complexity increases due to the additional component
Solution Approach 1:
The insert element combines multiple functions into a single component: it forms the upper edge of the recess receptacle, provides a bearing surface for the cover element, and includes anchor elements for secure attachment to the base body. This merging of functions improves locking security without requiring multiple separate components.
Solution Approach 2:
The insert element is a multi-functional component that serves as both the receptacle structure and the locking mechanism support. It provides the recess for the locking device, the bearing surface for the cover, and the anchor points for attachment, thereby improving locking security while adding only one universal component to the system.

AI summary
The invention relates to an insert element, in particular for the manufacture of a drainage object or for locking a cover on a polymer concrete body or a concrete body, for example on a yard drain or on a drainage channel, which is cast with a composite material, in particular concrete or polymer concrete, comprising at least one recess (11) which forms a receiving pocket for a locking element, a collar (12) which at least partially limits the recess and on which a bearing surface (13) for a cover element is arranged such that the collar (12) and the bearing surface (13) are essentially L-shaped in cross-section, wherein the insert element (10) has at least one anchor element (14) on the back side for a positive locking connection with the composite material.
