Solution Overview
Problem
Existing headlamps and similar light devices have ergonomic control issues, particularly when used blindly, as the small buttons are difficult to handle, especially with gloves, and previous solutions like flexible rubber covers do not provide optimal control.
Innovation Solution
A light unit with a waterproof casing featuring a control paddle that extends longitudinally and is operable in movement, allowing for ergonomic control of the light source without precise pressing, acting as both a control mechanism and a bezel for the optical unit, enabling intuitive operation even when the device is on the forehead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If small buttons are used on the housing, then the device size is reduced, but the ease of operation deteriorates especially when worn blind or with gloves
Solution Approach 1:
The control interface is extended from a two-dimensional button surface to a three-dimensional flexible paddle that can be actuated from multiple angles and positions. The paddle protrudes from the housing and can be operated by tapping, pressing, or flexing from various directions, solving the problem of inaccessible small buttons when the device is worn on the head.
Solution Approach 2:
The control paddle is designed as a flexible element that can dynamically change its shape and position during operation. It can be actuated in multiple positions and returns to its original position after use, providing ergonomic control that adapts to different user interactions while maintaining a compact overall device structure.
2Ease of operation
If a flexible rubber cover is used for control, then ease of operation is improved, but the structural complexity and sealing difficulty increase
Solution Approach 1:
The control paddle is integrated directly into the housing structure as a unified component rather than being a separate rubber cover. This merging of the control element with the housing simplifies the overall structure and reduces sealing complexity while maintaining the flexibility needed for easy operation.
Solution Approach 2:
The control paddle serves multiple functions: it acts as the control interface for actuating the light source, provides structural support, and maintains the waterproof sealing of the housing. This multi-functionality reduces the need for additional sealing components and simplifies the overall device design.
3Ease of operation
If control buttons are placed on the edge of the housing, then ease of operation is improved, but the manufacturing complexity and sealing difficulty increase
Solution Approach 1:
The control paddle is positioned on the front face of the housing rather than on the edge, utilizing the front surface dimension for control access. This allows the control interface to be easily accessible while maintaining a simple planar sealing surface on the housing edges, simplifying both manufacturing and sealing processes.
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 solution provides a compact yet wide control surface, improving ergonomics and simplifying production and sealing, allowing easy and intuitive control of the light device, even when used blindly.
Implementation Method 1
The control paddle having at least one plate which extends in a direction called longitudinal between a fixing zone on said light block and a free control part in flexure away from its fixing zone
