Door Frame Mounting Aid With Telescopic Spacer And Eccentric Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly aids for door frames are complex and do not simplify the process of inserting and adjusting the frame within a door opening, requiring multiple adjustments and additional components like spindles and tendons.
Innovation Solution
The assembly aid device features adjustable clamping devices with a telescopic spacer element and an eccentric lever system, allowing for precise alignment and parallel positioning of the frame legs, along with a tendon carrier for additional tension, enabling easier insertion and centering within the door opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional assembly aids with multiple spindles and tendons are used, then adjustment capability is improved, but device complexity increases
Solution Approach 1:
The assembly aid is divided into modular components: a clamping device with a jaw for gripping the frame, a separate telescopic spacer element for distance adjustment, and a tendon carrier for tensioning. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while maintaining full adjustment capability.
Solution Approach 2:
The telescopic spacer element acts as an intermediary between the two clamping devices, providing adjustable distance control without requiring direct mechanical connection between the clamping devices themselves. This mediator simplifies the overall mechanism by decoupling the clamping function from the adjustment function.
2Adaptability or versatility
If the adjusting jaw protrudes laterally beyond the clamping device, then adjustment range is improved, but ease of insertion worsens
Solution Approach 1:
The adjusting jaw is designed to be movable relative to the clamping device housing, allowing it to protrude laterally only when needed for adjustment. During insertion, the jaw can be retracted into the housing, presenting a compact profile that passes through door openings without obstruction. This dynamic positioning resolves the contradiction between adjustment range and ease of insertion.
3Manufacturing precision
If the spacer element is fixed in extended position, then manufacturing precision is improved, but ease of operation worsens
Solution Approach 1:
The spacer element employs a telescopic design with movable tubes that can be extended or retracted relative to each other. Once the desired distance is achieved, a locking mechanism secures the position, providing both adjustability during installation and precision during operation. This dynamic structure allows the spacer to adapt to different door frame configurations while maintaining accurate spacing.
Solution Approach 2:
The spacer element's length parameter can be changed by extending or retracting the telescopic tubes. The locking mechanism maintains the selected parameter value during operation, ensuring manufacturing precision, while allowing parameter changes during the adjustment phase, providing ease of operation.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the assembly process by allowing the door frame to be easily aligned and inserted, with the ability to apply tension for precise fitting, reducing the complexity and effort required for alignment and adjustment.
Implementation Method 1
The spacer element consists of two tubular elements that are telescopically inserted into one another and which can be fixed to one another in different extended positions using a clamping device
Implementation Method 2
An eccentric lever can be used to clamp the clamping jaw to the chuck
Implementation Method 3
The adjusting jaw or the clamping device does not have any elements that protrude laterally beyond the adjusting jaw
Implementation Method 4
a tendon is provided here, which is supported on the masonry in order to pull the frame against the opposite wall of the door opening
Implementation Method 5
To relocate the adjusting piston, a threaded spindle is preferably provided, which has a handle at its free end
