Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual and motor-driven riveting tools are often cumbersome, expensive, and unsuitable for narrow spaces due to their size and weight, and require complex adaptations for different rivet dimensions, making them impractical for sporadic or hard-to-reach riveting tasks.
Innovation Solution
A simplified hand riveting tool comprising a spacer element, thrust bearing unit, and screw/nut configuration that is lightweight, adaptable to various rivet diameters, and easily maneuverable, allowing for efficient fixing of collapsable rivets in tight spaces with minimal components and low manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If motor-driven riveting tools are used, then riveting power and efficiency are improved, but tool weight and dimensions increase making them difficult to transport and use in narrow spaces
Solution Approach 1:
The invention extracts and removes the motor-driven power source from the riveting tool, replacing it with a purely manual operating mechanism. This eliminates the heavy motor, battery, and power transmission components while retaining the core riveting function through direct manual manipulation of a simplified gripping unit and deformation mechanism.
Solution Approach 2:
The invention employs a simple, lightweight, disposable-like manual tool design that sacrifices the sustained high power of motor-driven tools in exchange for extreme portability and simplicity. The tool is designed to be light enough for easy transport and storage, accepting that it provides manual-level power rather than motor-level power.
2Weight of moving object
If manual riveting tools are used, then tool weight and dimensions are reduced, but riveting power and operational efficiency decrease
Solution Approach 1:
The invention incorporates a dynamic gripping unit that can be manually adjusted and deformed to match different rivet sizes and types. The gripping unit features movable jaws and adjustable positioning mechanisms that adapt to various rivet diameters, allowing a single lightweight tool to maintain effective riveting power across multiple applications through user-adjustable configuration rather than fixed rigid components.
Solution Approach 2:
The tool is divided into modular segments including a separate gripping unit, deformation mechanism, and handling components. This segmentation allows each part to be optimized for its specific function while keeping individual component weights low, and enables the operator to manipulate each segment independently to achieve the required riveting force through coordinated manual action.
3Adaptability or versatility
If manual riveting tools are designed for different rivet dimensions, then adaptability is improved, but tool complexity and number of replaceable parts increase
Solution Approach 1:
The gripping unit is designed as a universal component that can accommodate multiple rivet types and dimensions through adjustable jaw positioning and deformable gripping surfaces. The unit incorporates standardized measurement markings and adjustment mechanisms that allow a single gripping unit to serve multiple rivet sizes, eliminating the need for multiple specialized gripping units or complex replacement systems.
Solution Approach 2:
The tool employs nested or telescopic components within the gripping unit that can be adjusted to different positions to match various rivet diameters. Internal adjustment mechanisms are housed within the external gripping structure, allowing size adaptation without adding external complexity or requiring separate adjustment tools.

AI summary
Hand riveting tool (1; 101) for fixing a mechanical insert (2; 102), such as a rivet (2; 102) of collapsible type in a housing seat (3), comprises: a spacer element (5; 105) provided with an axial passage opening (6; 106) and comprising a contrasting end (7;107) that is suitable for coming to rest on, and contrasting, a front edge zone (B) of the rivet (2; 102); a thrust bearing unit (8; 108) arranged for resting on a second end (9; 109) of the spacer element (5; 105); a pulling member (10; 110) having a shape that is oblong and shaped for extending, along a longitudinal axis (A), through the thrust bearing unit (8; 108) and the passage opening (6; 106) of the spacer element (5; 105) for coupling through screwing with the rivet (2; 102); a threaded nut element (11; 111) that is screwable on said pulling member (10; 110) and arranged for resting on said thrust bearing unit (8; 108) opposite the spacer element (5; 105). The pulling member (10; 110) is provided with a shaped head (12; 112) for engaging a first key (C1) to counter rotation of the pulling member (10; 110) in relation to the rivet (2; 102). The nut element (11; 111) is shaped to engage a second key (C2) to be rotated with respect to the pulling member (10; 110). An unscrewing rotation of the nut element (11; 111) with respect to the pulling member (10; 110) is matched by an axial movement (T) of the pulling member (10; 110) such as to pull the rivet (2; 102) to deform the rivet (2; 102) into a collapsed configuration (W) in which it remains fixed in the housing seat (3).
