Orientable Lighting Appliance with Hidden Blocking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orientable lighting appliances lack a reliable and aesthetically pleasing mechanism for securely blocking the projector in the desired position, often relying on friction which compromises safety and stability, and existing solutions are complex or visually intrusive.
Innovation Solution
An orientable lighting appliance with a sliding rod and block bead mechanism that allows for precise positioning and secure locking of the projector, utilizing a hidden guide channel and threaded hole for easy manual operation, enabling the projector to rotate up to 80°-90° and maintain stability without external activating elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking mechanism is added to securely lock the projector in position, then the stability and reliability improve, but the device complexity and aesthetic appearance worsen due to external activating elements
Solution Approach 1:
The blocking mechanism is nested within the arm structure itself. The rod is received by a guide channel formed in the arm, and the block bead is received by a threaded hole also formed in the arm. This integration eliminates the need for separate external blocking components, reducing device complexity while maintaining blocking stability.
Solution Approach 2:
The activating element (block bead) is extracted from being an external separate component and is instead received within the arm structure through a threaded hole. This allows the activating element to be manipulated from the outside while being structurally integrated, simplifying the overall device architecture and improving aesthetics.
2Reliability
If a blocking mechanism with external activating elements is used, then the reliability improves, but the aesthetic appearance worsens due to visible external components
Solution Approach 1:
The blocking mechanism components are nested within the arm structure. The rod is received by a guide channel formed in the arm, and the block bead is received by a threaded hole also formed in the arm. This integration hides the blocking mechanism within the existing structure, maintaining aesthetic appearance while ensuring reliable blocking.
3Device complexity
If friction-based blocking is used, then the device complexity remains simple, but the reliability and stability worsen due to inadequate blocking after prolonged use
Solution Approach 1:
The blocking mechanism is designed to be self-locking through the threaded connection. When the block bead is manipulated to engage with the rod, the threads automatically provide the locking action without requiring additional active components or continuous energy input. This simple self-service mechanism ensures reliable blocking while maintaining device simplicity.
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 stable and secure blocking mechanism that is easy to activate and invisible from the outside, enhancing safety and aesthetic appeal by allowing precise orientation and locking of the projector, addressing the limitations of existing technologies.
Implementation Method 1
the blocking is simply due to the friction caused in correspondence with the joining hinge between the arm fixed to the wall and the projector itself
