Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scaffold plank clamps do not adequately secure planks, leading to relative movement and safety hazards, and existing solutions are either inefficient or pose tripping risks due to their placement.
Innovation Solution
A clamp with adjustable telescopic tubing and upright stops that secures planks from beneath, eliminating vertical deflection and relative movement, and allows for fine adjustments using a ⅞ socket, preventing tampering and ensuring stability across various scaffold widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If planks are not secured together, then installation is simple and quick, but relative movement between planks occurs creating safety hazards
Solution Approach 1:
The clamp apparatus is designed to be self-aligning through its upright stops that engage with the outer edges of adjacent planks, automatically positioning itself correctly during installation without requiring precise manual alignment or complex adjustment procedures
Solution Approach 2:
The clamp apparatus is divided into distinct functional segments: upright stops for engagement, an adjustable bar for compression, and a fastening mechanism. This segmentation allows for simple installation while providing reliable plank stabilization through coordinated action of each component
2Reliability
If a transverse board is attached to the upper surface of planks, then planks are secured together, but workers may trip over it
Solution Approach 1:
Instead of placing the securing mechanism on top of the planks where it would create a tripping hazard, the clamp apparatus is inverted and positioned beneath the planks. The upright stops engage with the outer edges from below, securing the planks together while remaining hidden and non-obtrusive to workers walking on the platform
3Object-affected harmful factors
If a transverse board is attached to the lower side of planks, then tripping risk is eliminated, but attachment is difficult and time-consuming
Solution Approach 1:
The clamp apparatus replaces the complex mechanical operation of attaching boards from underneath with a simplified system using upright stops that slide onto plank edges and an adjustable bar that compresses planks together. This substitution maintains the safety benefit of lower-side attachment while dramatically reducing installation complexity and time
4Adaptability or versatility
If plank width varies, then different scaffold configurations are possible, but clamp must be adjusted for each width
Solution Approach 1:
The bar component of the clamp apparatus is designed to be longitudinally adjustable, allowing dynamic adaptation to different plank widths and scaffold configurations. This adjustability enables the same clamp design to serve multiple purposes across various scaffold types without requiring multiple specialized tools
5Reliability
If clamp is placed on top of planks, then plank security is improved, but it becomes a tripping hazard
Solution Approach 1:
The clamp apparatus inverts the conventional placement by positioning its main body beneath the planks rather than on top. The upright stops extend upward to engage with plank edges, providing effective stabilization while keeping the bulk of the apparatus hidden below the walking surface, eliminating the tripping hazard
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
The clamp provides a stronger, safer platform by uniformly distributing loads and reducing the risk of plank movement, enhancing safety and load capacity while avoiding tripping hazards and unauthorized tampering.
Implementation Method 1
The clamp features a threaded adjustment mechanism that converts rotational motion into linear compression, applying clamping force to the planks
Implementation Method 2
The clamp features adjustable telescopic tubing which allows for the user to adjust the clamp to be utilized on a number of different scaffolding frame widths

AI summary
The invention comprises a clamp that is easily and quickly attached to planks such as those in a scaffold platform that is defined by plural planks laid side-by-side to define a platform in a scaffold structure. The clamp resides beneath the planks and is therefore not a trip-hazard for workers, and the clamp is readily adjustable to compress the planks to one another to stabilize the platform. The invention creates a stronger and more stable platform by eliminating the vertical deflection of each individual plank as well as any other relative movement. The inventive clamp features adjustable telescopic tubing which allows for the user to adjust the clamp to be utilized on a number of different scaffolding frame widths. Fine adjustments to the width of the clamp are made available through a threaded clamping nut that can only be adjusted using a ⅞th inch socket, which is a size typically carried by a scaffolding worker. A guard post apparatus may be attached to the clamps to allow for a safety railing.
