Solution Overview

Problem

Existing splinter catchers for pliers are difficult to assemble and tend to slip when in use, inadequately protecting against flying nail splinters, which poses hygiene and safety risks and requires frequent realignment.

Innovation Solution

A splinter catcher with a spring clamp that securely attaches to the pliers head, using a curved leaf spring design that engages behind the pliers' handle, ensuring stable storage and preventing slipping during use, and optionally featuring hooks for additional grip.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a splinter catching plate is detachably mounted on the pliers head, then it can be removed and replaced, but it becomes cumbersome to install and easily slips during use

Engineering Contradiction:
Improvedetachable mountingVSAvoidmounting stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The spring clip is integrated into the splinter catching plate structure, with the clip forming part of the plate assembly. This nested integration ensures the clip and plate move together as a unit during attachment and detachment, preventing separation or slippage while maintaining ease of installation.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The spring clip automatically engages with the pliers joint through elastic deformation, creating self-locking functionality. When the plate is attached, the spring clip compresses and then locks into place on its own, providing secure mounting without requiring additional fastening steps or tools.

Inventive Principle:
Principle #25Self-service

2Reliability

If the splinter catching plate is securely attached to prevent slipping, then mounting stability improves, but the assembly process becomes more complex

Engineering Contradiction:
Improvemounting stabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The spring clip is designed as a separate functional element integrated into the plate, allowing independent optimization of the clipping mechanism from the catching plate. This segmentation enables simple manufacturing of each component while achieving complex secure mounting functionality when assembled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring clip utilizes elastic deformation parameters to transition from a compressed state during installation to a locked state during use. By changing the physical state of the spring material through elasticity, the system achieves secure attachment without complex mechanical fasteners.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If the cutting edges are covered when pliers are closed, then protection against flying nail splinters improves, but the device structure becomes more complex

Engineering Contradiction:
Improveprotection against flying splintersVSAvoiddevice structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The splinter catching plate serves multiple functions: it collects flying nail splinters, covers the cutting edges when closed, and provides a mounting surface for the spring clip attachment mechanism. This multi-functionality reduces the need for separate protective components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The protective function of covering cutting edges is merged with the splinter collection function in a single plate structure. The plate simultaneously performs edge coverage and splinter containment, eliminating the need for separate protective shields or covers.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to a splinter catcher for detachable connection to pliers, wherein the pliers have two double-sided levers, each with a handle section for actuating the pliers, connected to each other via a joint, and forming a plier head with cutting edges. The splinter catcher has a splinter catcher plate which, when the splinter catcher is mounted, covers the cutting edges of the plier head in the closed position. The invention further relates to a combination of pliers and a splinter catcher that can be detachably connected to the pliers. To propose a splinter catcher for pliers that is easy to mount and provides lasting protection against flying nail splinters during normal use, the invention suggests that the splinter catcher plate has a spring clamp which, when the splinter catcher is mounted, engages the joint.
