Adjustable Packer Apparatus for Door Frame Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packers used in door and window frame adjustments are often inadequate, as they can be difficult to adjust, prone to falling out of place, require frequent maintenance, and are not easily reusable due to damage during installation and removal, leading to increased construction time and costs.
Innovation Solution
An adjustable packer apparatus comprising two planar members with adjustment means, such as a bolt and threaded members, allowing for perpendicular movement to adjust the clearance space between support members, enabling easy adjustment and reuse by rotating the bolt to narrow or widen the gap without the need for extensive woodworking or reinstallation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing make-shift packers are used for adjusting door frames, then adjustment can be achieved, but the packers require frequent maintenance, are prone to falling out of place, and are not easily reusable
Solution Approach 1:
The packer incorporates an adjustable mechanism with a bolt and threaded member that allows dynamic adjustment of the clearance space. The bolt can be rotated to move the first planar member perpendicular to the second planar member, enabling the packer to adapt to different adjustment requirements while maintaining stable positioning without frequent maintenance
Solution Approach 2:
The packer is divided into separate components including a first planar member, a second planar member, and an adjustment mechanism with bolt and threaded member. This segmentation allows the adjustable component to be removed and reused for different adjustments without damaging the entire packer assembly, improving reusability and reducing maintenance requirements
2Manufacturing precision
If multiple packers or reworked packers are used to achieve adjustment, then the desired clearance adjustment can be obtained, but construction time and costs significantly increase
Solution Approach 1:
The packer design with adjustable mechanism serves multiple functions: it can adjust clearance spaces of different sizes, accommodate various door frame positions, and be reused for multiple adjustments. This eliminates the need to use multiple different packers or perform rework, significantly reducing construction time while maintaining precise clearance adjustment capability
Solution Approach 2:
The packer is pre-assembled with the adjustment mechanism in place, allowing the clearance space to be adjusted simply by rotating the bolt without requiring on-site woodworking or complex installation procedures. This preliminary preparation of the adjustment mechanism greatly accelerates the construction process
3Adaptability or versatility
If existing packers are used, then adjustment is possible, but they require fiddly woodworking to make them fit in small confined gaps and may need trimming or shaping
Solution Approach 1:
The adjustable mechanism allows the packer to dynamically adapt to different clearance space dimensions by rotating the bolt to move the first planar member perpendicular to the second planar member. This eliminates the need for fiddly woodworking or trimming to make fixed-size packers fit, as the adjustment is achieved through simple rotational movement of the bolt
Solution Approach 2:
The threaded member is nested within the first planar member, and the bolt is inserted through the second planar member to engage with the threaded member. This nested configuration allows the adjustment mechanism to be compact and easy to install in small confined gaps without requiring extensive woodworking
4Manufacturing precision
If planar packer members are used for adjustment, then clearance adjustment can be achieved, but inadvertent unwanted rotation of one planar member with respect to the other requires regular re-adjustment
Solution Approach 1:
The adjustment mechanism uses a bolt that moves the first planar member perpendicular to the second planar member rather than allowing rotation. This dynamic linear adjustment mechanism maintains stable orientation of the planar members while achieving the desired clearance adjustment, eliminating the need for regular re-adjustment due to rotation

Function Achieved in This Case
The adjustable packer apparatus simplifies the adjustment process, reduces construction time and costs, and allows for easy re-adjustment of door frames without removing them, while being durable and reusable, addressing the limitations of existing packers.
Implementation Method 1
adjustment means includes at least one bolt having a head at one end, adjusting end at other end and outer thread body movably attached to and protruding from the rear or second planar member and the first or front planar member has a threaded member protruding therefrom, wherein the bolt is threadingly engaged with the threaded member

AI summary
An adjustable packer apparatus for adjusting a clearance space between at least two support members. The adjustable packer apparatus having at least one first and one second planar member and adjustment means. The planar members are configured and spaced from each other and each include an one aperture there through whereby one planar member is movably attachable by the adjustment means through alignment of the at least one aperture of one planar member to the other planar member. The adjustment means includes at least one bolt attached to the second planar member. The first planar member has a threaded member protruding therefrom, wherein the bolt is threadingly engaged with the threaded member. The second planar member is attachable to one of the two support members which provides a stiffer or less flexible support than that provided by or for the first planar member. A method of installation is also disclosed.
