Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assembling cladding profiles on joinery frames are inefficient, leading to inconsistent tightening, noise pollution, and increased risk of musculoskeletal disorders due to repetitive hammering and clamp usage.
Innovation Solution
A tool comprising a first member with a through opening and a second member that rotates relative to the first member, allowing the tool to transition between unlocking and locking positions. This tool securely clamps two profiles together, compressing a longitudinal sealing joint for watertight assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamps are used to hold the added tap in position, then the added tap can be secured to the frame profile, but the tightening is not controlled and constant along the entire length
Solution Approach 1:
A compression tool acts as an intermediary device between the operator and the added tap, providing controlled and constant compression force through its mechanical design. The tool includes a compression element that distributes force evenly along the added tap length, ensuring uniform tightening without the variability inherent in manual clamp placement.
Solution Approach 2:
The compression tool transforms the application method by changing from discrete clamp forces to continuous compression force. The tool's design parameters (compression element geometry, force distribution) are optimized to deliver constant tightening pressure along the entire added tap length, improving manufacturing precision.
2Ease of operation
If hammers are used to tap the added tap to compress the sealant, then the added tap can be positioned, but additional noise is created and operators can develop musculoskeletal disorders
Solution Approach 1:
The patent replaces the hammer-tapping mechanical system with a compression tool system. Instead of impact forces from hammers, the tool uses controlled compression forces applied through a compression element, eliminating noise and health risks while maintaining positioning effectiveness.
Solution Approach 2:
The compression tool is designed to be self-regulating, where the compression force is automatically applied and maintained through the tool's mechanical design. The tool's weight and structure provide the necessary force without requiring repetitive manual hammering, reducing operator strain and health risks.
3Reliability
If multiple clamps are arranged along the profiles for tightening, then the added tap can be held in position, but the assembly process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent merges multiple clamp functions into a single compression tool. Instead of using multiple discrete clamps arranged along the profile, the compression tool integrates a compression element that contacts and secures the added tap at multiple points simultaneously, reducing the number of tools and operations required.
Solution Approach 2:
The compression tool serves multiple functions: it positions the added tap, compresses the sealant, and holds the assembly in position—all through a single tool operation. This multi-functionality eliminates the need for multiple specialized clamps and operations, improving productivity.
4Reliability
If sealant is applied in a longitudinal groove and the added tap is clipped in, then watertight assembly can be achieved, but excess sealant must be cleaned and the process is complex
Solution Approach 1:
The compression tool applies preliminary compression force to the added tap, ensuring the sealant is properly compressed and sealed before final assembly steps. This preliminary action prevents sealant leakage and eliminates the need for subsequent cleaning operations, simplifying the overall process.
Solution Approach 2:
The patent converts the potential harm of excess sealant leakage into a benefit by using the compression tool to control sealant compression from the outset. The controlled compression ensures optimal sealant distribution without overflow, turning a potential cleaning problem into a seamless assembly process.

AI summary
The invention relates to an assembly comprising a tool (100) and two profiles, the tool being intended for temporarily clamping the profiles together. The tool comprises: - a first member (200) comprising a fixing element (240), - a second member (300), movable by rotation relative to said first member, around an axis of rotation A, and comprising a fixing member (340) at the head (330). The tool moves between an unlocking position, in which the fixing element (240) and the fixing member (340) are spaced apart from each other, and a locking position in which the fixing element (240) and the fixing member (340) are brought closer to each other, each bearing respectively on one of the two profiles. The transition from the unlocked position to the locked position is carried out by a rotation, along the axis of rotation A, of the second member relative to the first member.
