Articulated Device Holder With Lifted Link Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device holders lack a reliable mechanism to prevent finger trapping and collisions during manual operation, especially when adjusting the position of devices like monitors, which can lead to accidents and damage.
Innovation Solution
A device holder with a base part and a coupling part connected via a joint arrangement featuring a height-adjustable link and a lifting mechanism that automatically moves the link out of a potential collision area when it enters a safety zone, ensuring collision-free operation and protecting against finger entrapment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple arms and joints are added to increase adjustability, then the device holder can achieve more positioning options, but the risk of collisions between components increases
Solution Approach 1:
The lifting mechanism proactively detects when a link is about to enter a collision zone and automatically initiates a lifting action to prevent the collision before it occurs. This preliminary protective action eliminates the need for reactive measures after collision detection.
Solution Approach 2:
The collision prevention mechanism performs preliminary actions by continuously monitoring link positions and pre-lifting links before they enter collision zones. This advance preparation ensures that when rotational movements occur, links are already positioned safely, preventing collisions proactively.
2Ease of operation
If manual operation is used for simplicity, then the device holder is easy to operate, but finger trapping hazards cannot be avoided
Solution Approach 1:
The lifting mechanism acts as an intermediary safety system between the user's manual operation and the potentially hazardous moving parts. It automatically intervenes to lift links when collision risks are detected, protecting users without requiring them to manually control each movement.
Solution Approach 2:
The device holder performs self-protection by automatically detecting potential finger trapping hazards and initiating corrective lifting actions without user intervention. The system monitors its own state and takes protective measures independently, maintaining ease of operation while eliminating hazards.
3Object-affected harmful factors
If visual grips are added to improve safety, then user awareness is enhanced, but reliability depends on user skill and recognition
Solution Approach 1:
The lifting mechanism provides automatic safety without requiring user awareness or skill. It independently monitors link positions, detects potential hazards, and executes protective lifting actions autonomously, making safety consistent and independent of user behavior.
Solution Approach 2:
The patent replaces reliance on user cognitive processes (recognizing and operating visual grips) with an automated mechanical sensing and actuation system. This substitution transforms safety from a user-dependent function to a system-inherent function, ensuring consistent protection.

AI summary
The invention relates to a device holder (200) with a base part (220) for mounting on a reference object (2) and a coupling part (210) for coupling a device (1) to be held. The invention further comprises a joint arrangement (201) coupling the base part (220) and the coupling part (210), which includes at least one height-adjustable first link (100), a first pivot bearing (202a) in which the first link (100) is rotatably mounted about a pivot bearing axis (D1), and a lifting mechanism (HM) which, when the first link (100) rotates about the pivot bearing axis (D1) within a predetermined angular range of the first pivot bearing (202a), causes a stroke (h) parallel to the pivot bearing axis (D1), at least when the first link (100) is located within a safety zone around a potential collision zone (K).
