Adjustable Door Frame Wall Clamp for Variable Wall Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door frames are not flexible in terms of wall thickness and usability, as the wall clamp is a fixed part that does not accommodate varying wall conditions effectively.
Innovation Solution
A door frame with a groove on the rear of the frame post at an angle of 10-50 degrees, where the second clamping part's fastening part protrudes into the groove and is adjustable using displacing means, such as screws, allowing for movement and adjustment of the clamping jaws to accommodate different wall thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wall clamp is made as a fixed part on the frame post, then the manufacturing process is simplified, but the adaptability to different wall thicknesses deteriorates
Solution Approach 1:
The second clamping part is made movable relative to the frame post through a groove and displacing means (screw mechanism), allowing the clamping jaw position to be adjusted dynamically. This enables the wall clamp to adapt to different wall thicknesses while maintaining a relatively simple fixed structure for the first clamping part, thus balancing manufacturing ease with adaptability.
2Adaptability or versatility
If the second clamping part is made movable with displacing means, then the adaptability to different wall thicknesses is improved, but the device complexity increases
Solution Approach 1:
The wall clamp is divided into two clamping parts: a first clamping part that is fixed to the frame post and a second clamping part that is movable. This segmentation allows the complex adjustable mechanism to be isolated to only the necessary second clamping part, rather than making the entire wall clamp complex, thus reducing overall device complexity while maintaining adaptability.
3Adaptability or versatility
If the groove is provided at an angle of 10-50 degrees, then the universality of the door frame is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The groove is designed with a specific angle range (10-50 degrees) that optimizes the balance between universality and manufacturing precision. This angular parameter allows the displacing means to effectively move the second clamping part along the groove while accommodating various wall thicknesses, providing universal applicability without requiring extremely precise manufacturing tolerances.

AI summary
A door frame 1 has a frame post 3 which is secured with a rear side 5 against a reveal 7 of a wall opening 9 by means of a number of wall clamps 13. Each wall clamp 13 has two clamping parts 15, 17, each consisting of a fastening part 19, 21 and a clamping jaw 23, 25. At the rear 5, the frame post 3 is provided with a groove 27 which extends over the entire length of the frame post 3 and is present at an angle 29 of 10-50 degrees to the rear side. The fastening part 21 of the clamping part 17 partly protrudes into the groove 27 and is displaceable in and out of the groove 27 by turning screws 31 more or less in the door frame 3, which screws protrude through holes 35 present in the clamping jaw 25.
