Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display stands with torque hinges struggle to maintain a desired tilt angle when the weight of the item to be displayed is outside the expected range, and these hinges cannot be adjusted without tools and knowledge.
Innovation Solution
A tool-free adjustable torque system that includes a frame hingedly coupled to a base, a control bar with left-hand and right-hand threaded portions, and a grip for simultaneous rotation of the threaded portions, allowing for adjustment of spring tensions without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a torque hinge with a fixed force setting is used, then the display stand can maintain a desired tilt angle for items within the expected weight range, but it cannot accommodate items with weights outside this range and cannot be adjusted without tools
Solution Approach 1:
The patent transforms the static torque hinge into a dynamic adjustable system. The control bar with opposite-hand threads allows the user to dynamically adjust the spring tension by rotating the grip, changing the torque setting from fixed to variable. This enables adaptation to different item weights while maintaining ease of operation through a simple manual adjustment mechanism.
Solution Approach 2:
The adjustment mechanism is designed to be self-service, allowing users to adjust the torque setting without requiring tools or specialized knowledge. The grip and control bar provide an intuitive interface where users can directly manipulate the spring tension to match the weight of the item being displayed, making the system self-adjusting to user needs.
2Adaptability or versatility
If a torque hinge with a fixed force setting is used, then the structure remains simple, but the tilt angle cannot be maintained when item weight deviates from the expected range
Solution Approach 1:
The adjustment mechanism is nested within the existing hinge structure. The control bar with opposite-hand threads is integrated into the hinge assembly, with the grip fitting into the housing. This nesting approach allows the hinge to transition from a simple fixed-torque design to an adjustable torque design without requiring a complete structural overhaul, thus improving adaptability while controlling complexity.
3Force
If the torque hinge force setting is increased to accommodate heavier items, then heavier items can be supported, but lighter items cannot be maintained at the desired tilt angle
Solution Approach 1:
The patent enables continuous change of the torque parameter through the adjustable spring tension mechanism. By rotating the grip on the control bar, users can vary the spring tension and thus the torque force applied by the hinge. This parameter adjustment capability allows the same hinge to provide appropriate torque for both light and heavy items, covering a wide weight range without requiring multiple fixed-setting hinges.
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 quick and easy adjustment of the display stand's tilt angle to accommodate a wide range of weights, ensuring the item is maintained at the desired viewing angle without requiring tools or technical knowledge.
Implementation Method 1
The bar includes a left-hand threaded portion, a right-hand threaded portion, and a grip configured to enable simultaneous rotation of the left-hand threaded portion and the right-hand threaded portion. A first nut is in threaded engagement with the left-hand threaded portion and a second nut is in threaded engagement with the right-hand threaded portion.
Implementation Method 2
A first spring in tension is coupled to the first nut and to the platform, and a second spring in tension is coupled to the second nut and to the platform. The grip is rotated resulting in the first nut and second nut being moved along the control bar in opposing directions to enable simultaneous adjustment of the tension in the first spring and the tension in the second spring.

AI summary
Methods and systems of tool-free adjustment of torque used to maintain the viewing angle of a display stand are performed. In one exemplary embodiment, a method is performed by a device having a platform hingedly coupled to a base. A bar rotatably supported by the base includes a left-hand threaded portion, a right-hand threaded portion, and a grip configured to enable simultaneous rotation of both threaded portions. A first nut is in threaded engagement with the left-hand threaded portion, and a second nut is in threaded engagement with the right-hand threaded portion. A first spring is coupled to the first nut and the platform, and a second spring is coupled to the second nut and the platform. When the bar is rotated via the grip, the first and second nuts move in opposing directions to enable simultaneous tension adjustment of the first and second springs.
