Camera Flash Housing with Sliding Actuator Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intermediate signal transmission units for wireless communication between cameras and remote flash devices are complex and require users to visually operate buttons, which can be inconvenient and prone to accidental activation.
Innovation Solution
A housing design for an intermediate signal transmission unit that allows control of switches through a simple relative movement of two housing parts, eliminating the need for external buttons and enabling operation without looking at the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external buttons are provided on the intermediate signal transmission unit, then the device is easier to operate, but the device becomes more prone to accidental activation and requires visual attention
Solution Approach 1:
The control functionality is extracted from external buttons and integrated into the housing structure itself. The first housing part is made displaceable relative to the second housing part, and this displacement directly actuates switches through integrated actuators, eliminating the need for separate external buttons that could be accidentally activated.
Solution Approach 2:
The control mechanism is merged with the housing structure. The displaceable first housing part incorporates actuators that directly control switches, combining the housing with the control function into a single integrated system rather than having separate control elements.
2Device complexity
If external buttons are provided on the intermediate signal transmission unit, then the device structure becomes simpler, but the device requires visual attention for operation
Solution Approach 1:
The displacement of the first housing part serves as an intermediary mechanism between the user's manual operation and the switch activation. This intermediary mechanical linkage allows control without visual attention while maintaining operational simplicity.
3Object-affected harmful factors
If the first housing part is made displaceable to control switches, then accidental button presses are reduced, but the device complexity increases
Solution Approach 1:
The control mechanism is merged with the housing structure. The displaceable first housing part incorporates actuators that directly control switches, combining the housing with the control function into a single integrated system rather than having separate control elements.
Solution Approach 2:
The control functionality is extracted from external buttons and integrated into the housing structure itself. The first housing part is made displaceable relative to the second housing part, and this displacement directly actuates switches through integrated actuators, eliminating the need for separate external buttons that could be accidentally activated.
4Ease of operation
If the housing is designed with cylindrical shape and rotational movement, then the operation becomes more intuitive without visual attention, but the manufacturing complexity increases
Solution Approach 1:
The housing is designed with cylindrical shape, providing a curved, ergonomic form that is intuitive to grasp and rotate. This curved geometry facilitates operation without visual attention while the modular housing design keeps manufacturing manageable.

AI summary
A housing (30) for an intermediate signal transmission unit for wireless communication between a camera and a remote flash device, the housing comprising connected first and second housing parts (40, 50). The second housing part accommodates signal transmission components (12) of the intermediate signal transmission unit and comprises a connector (60), connecting the housing to a camera. The first housing part (40) is displaceable in relation to the second housing part (50), and comprises at least one actuator (41) configured to control at least one switch (70; 71), said switch being part of the signal transmission components (12) and located in the second housing part (50). The at least one actuator (41) is movable in relation to the second housing part (50), comprising a first position in which the actuator can control the switch (70; 71) to be in a first state, and a second position in which the actuator can control the switch to be in a second state, by means of displacing the first housing part (40) and the actuator (41) in relation to the second housing part (50).
