Pliers Illumination Structure for Unobstructed Workpiece Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination structures for pliers mount light emitting elements on the clamping jaws, causing the jaws to shield the light when expanded, making it inconvenient to maintain a workpiece in a dim area as the worker needs to hold a flashlight with one hand and pliers with the other.
Innovation Solution
The illumination structure fixes a light emitting element between the first and second clamping jaws, with a rotatable connecting portion housing the illumination device, allowing the light to be emitted directly without being obstructed by the jaws, featuring a coupling seat with a control button and a fixing column for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the light emitting element is mounted on the two clamping jaws, then the illumination structure can be integrated with the pliers, but the two clamping jaws shield the lights when expanded outwardly
Solution Approach 1:
The light emitting element is extracted from the clamping jaws and relocated to the rotatable connecting portion, which houses the illumination device in an accommodation groove. This separation eliminates the shielding problem while maintaining integration with the pliers structure.
Solution Approach 2:
The illumination device is positioned in a different spatial dimension - from the clamping jaw surface to the rotatable connecting portion between the handle and jaw. The first opening in the accommodation groove allows light to exit toward the workpiece without being blocked by the expanded jaws.
2Illumination intensity
If the worker holds a flashlight with one hand and pliers with the other hand to illuminate a workpiece, then the workpiece can be illuminated, but the maintenance operation becomes inconvenient
Solution Approach 1:
The flashlight function is merged with the pliers by integrating the illumination device into the rotatable connecting portion. This combination allows the worker to use both hands for the maintenance operation while the pliers provide both gripping and illumination functions.
Solution Approach 2:
The pliers become self-illuminating through the integrated illumination device that emits light directly toward the workpiece. The tool serves its own illumination needs without requiring an external flashlight, enabling hands-free operation.
3Illumination intensity
If the light emitting element is fixed between the first clamping jaw and second clamping jaw, then the light can be emitted directly without obstruction, but the light may be blocked by the jaws when they are in the closed position
Solution Approach 1:
The rotatable connecting portion acts as an intermediary structure that houses the illumination device and positions it optimally. The first opening in the accommodation groove serves as an intermediary light path that directs light toward the workpiece while avoiding obstruction from the closed jaws.
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
Enables direct illumination of an object without light obstruction, enhancing maintenance convenience by allowing hands-free operation with the pliers, as the light is emitted between the jaws, reducing the need to hold a separate flashlight.

AI summary
An illumination structure for pliers contains: a first part, a second part, and an illumination device. The first part includes a first clamping jaw, a first handle, and a first rotatable connecting portion between the first clamping jaw and the first handle. The second part includes a second clamping jaw, a second handle, and a second rotatable connecting portion between the second clamping jaw and the second handle, wherein the first rotatable connecting portion of the first part and the second rotatable connecting portion of the second part are rotatably connected together. The first rotatable connecting portion has an accommodation groove configured to house the illumination device, and the accommodation groove has a first opening communicating with the first clamping jaw and the second clamping jaw and has a second opening communicating with the first handle. The illumination device includes a light emitting element and a control button.
