Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional c-clamps used in solid surface fabrication are inefficient, leading to poor lamination quality, high replacement costs, and increased risk of repetitive motion injuries due to uneven clamping pressure, user fatigue, and contamination issues with adhesive materials.
Innovation Solution
A solid surface clamp with a top jaw and bottom jaw connected by a bolt, featuring an elongated stiffening member for even force distribution and alignment surfaces, along with a shroud to protect the compression device from adhesive contamination, allowing for fewer clamps and easier alignment during the lamination process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional c-clamps are used for laminating, then the basic clamping function is achieved, but uneven clamping pressure and poor lamination quality result
Solution Approach 1:
The clamp is divided into multiple independent jaws (at least three jaws) distributed along an elongated member, allowing each jaw to apply clamping force at different locations. This segmentation enables even pressure distribution across the laminated material without requiring perfect manual tightening of each individual clamp.
Solution Approach 2:
Multiple clamping jaws are combined onto a single elongated member body, creating one integrated clamping device that functions as multiple clamps would. This merging allows simultaneous multi-point clamping with uniform pressure distribution while reducing the number of separate clamp operations needed.
2Manufacturing precision
If multiple c-clamps are spaced closely together to achieve even pressure, then lamination quality improves, but the number of clamps and complexity increases
Solution Approach 1:
Multiple clamping jaws are merged onto a single elongated member, creating one integrated device that provides multi-point clamping. This eliminates the need for multiple separate c-clamps while achieving even pressure distribution across the workpiece.
Solution Approach 2:
The single clamp body with multiple jaws serves the function of multiple individual clamps simultaneously. Each jaw can independently contact the workpiece at different locations, providing universal clamping capability across the entire width of the material being laminated.
3Reliability
If c-clamps are tightened manually to achieve even torque, then clamping function is achieved, but user fatigue and risk of repetitive motion injuries increase
Solution Approach 1:
The clamping force is segmented and applied at multiple locations by different jaws simultaneously through a single operating mechanism. This segmentation allows the operator to apply force once at the handle, which is then distributed evenly to multiple jaws, eliminating the need for repeated manual tightening operations.
Solution Approach 2:
Multiple clamping actions are merged into a single operating motion. The handle rotation simultaneously actuates all jaws to engage and apply clamping force, combining what would otherwise require multiple separate tightening operations into one action.
4Ease of manufacture
If compression device threads are exposed during lamination, then the clamping mechanism functions, but adhesive contamination renders threads inoperable requiring replacement
Solution Approach 1:
The compression device threads are extracted from the main body and relocated to the distal end of the elongated member, away from the clamping zone where adhesive is applied. This spatial separation protects the threads from contamination while maintaining the mechanical function of the clamping mechanism.
Solution Approach 2:
The elongated member acts as an intermediary between the compression device and the clamping jaws. It transmits the clamping force from the protected compression device to the jaws while physically isolating the threads from direct exposure to adhesive materials.
5Productivity
If fewer clamps are used to reduce complexity, then operation time decreases, but clamping pressure distribution becomes insufficient
Solution Approach 1:
Multiple clamping functions are merged into a single clamp device with multiple jaws, allowing one clamp to perform the work of several traditional clamps. This maintains even pressure distribution across the material while reducing the total number of clamp operations needed.
Solution Approach 2:
The clamp extends in the lateral dimension with multiple jaws distributed along its length, rather than concentrating force at a single point. This dimensional expansion allows a single clamp to cover the entire width of the material, providing even pressure distribution without needing multiple clamps spaced along the edge.

AI summary
A solid surface clamp is provided. The solid surface clamp has a top jaw and a bottom jaw. A connecting rod is attached to one of the jaws, and slideably extends through the other jaw. Alignment surfaces may be incorporated into the jaws to assist in accurately positioning the material to be laminated. A compression device is connected to the portion of the connecting rod that extends through the jaw. A shroud shields the compression device, thereby protecting the compression device from contamination by the laminating adhesive. An elongated stiffening member may be used to apply the clamping force over a longer surface, allowing for greater spacing between clamps and extended regions of even clamping pressure.
