Spring Clamp Face Frame Assembly Without Visible Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for securing a face frame to a cabinet box are labor-intensive and require the use of nails, staples, pocket screws, or other visible fastening elements, which complicate the process and result in unsightly nail holes that need filling.
Innovation Solution
A modified spring clamp with elongated lever arms and a clamping mechanism that allows for secure attachment of the face frame to the cabinet box without the need for nails or other fasteners, using glue and strategically placed holes or shelf adjustment openings to clamp the face frame onto the cabinet box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If nails, staples, pocket screws, or other fasteners are used to secure the face frame to the cabinet box, then the face frame is securely attached, but visible fastening elements and nail holes are created that require filling and concealment
Solution Approach 1:
The patent removes traditional fasteners (nails, screws, staples) from the attachment process entirely. Instead, it uses spring clamps with pins that engage through pre-drilled holes in the cabinet box sides to secure the face frame, eliminating the need for visible fastening elements on the face frame surface.
Solution Approach 2:
The spring clamp acts as an intermediary device between the face frame and cabinet box. The clamp with its elongated lever arms and clamping jaws provides the securing force, while the pin engages through holes in the cabinet box sides rather than through the face frame, thus avoiding visible fasteners on the finished surface.
2Strength
If conventional fastening methods are used to secure the face frame, then the attachment is secure, but the process becomes labor-intensive requiring filling and concealing fastener holes
Solution Approach 1:
The patent eliminates the time-consuming steps of driving nails or screws and subsequently filling and sanding holes. The spring clamp system secures the face frame through a single operation, and the pins engage through holes in the cabinet box sides rather than the face frame, eliminating the finishing step entirely.
3Ease of operation
If spring clamps with modified lever arms are used to clamp the face frame to the cabinet box, then the attachment process is simplified and fasteners are hidden, but the clamp design becomes more complex
Solution Approach 1:
The spring clamp uses elastic deformation of the spring mechanism to provide clamping force. The elongated lever arms are designed to flex and apply consistent pressure on the face frame and cabinet box, maintaining secure attachment while accommodating slight variations in positioning.
Solution Approach 2:
The patent extends the lever arms of the spring clamp in the longitudinal direction to reach from the front of the cabinet box to the rear. This dimensional extension allows the clamp to engage and secure the face frame effectively while the pin engages through holes in the side walls, distributing the fastening function across different spatial dimensions.
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
This method simplifies the attachment process, eliminates the need for visible fasteners, and allows for a more aesthetically pleasing finish by using glue and spring clamps to secure the face frame, reducing labor and hiding fastener holes with caps or finish panels.
Implementation Method 1
a spring mounted on the pivot pin and engaging the inner sides of the lever arms to yieldably urge the lever arms to their clamping positions
Implementation Method 2
using glue and strategically placed holes or shelf adjustment openings to clamp the face frame onto the cabinet box
