Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication terminals with adjustable tilting angles lack stability when force is applied, causing inconvenience and instability during use due to inadequate support structures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lever mechanism is used to adjust the tilting angle, then the terminal body can be adjusted to different angles, but the terminal body sways and cannot be stably fixed when force is applied
Solution Approach 1:
The patent employs a dynamic locking mechanism where a pawl selectively engages with different engagement portions along the slider's longitudinal direction. This allows the system to transition between different stable states (different tilting angles) while maintaining firm fixation at each position, resolving the contradiction between adjustability and stability.
Solution Approach 2:
The patent introduces intermediate components including a slider with engagement portions, a pawl for selective engagement, and a spring for providing locking force. These intermediary elements mediate between the adjustment lever and the terminal body, enabling both angle adjustment and stable fixation without direct rigid connection.
2Stability of the object's composition
If a rigid support structure is used to fix the terminal body, then the terminal body can be stably fixed, but the adjustment mechanism becomes complex and difficult to operate
Solution Approach 1:
The support structure is segmented into modular components: a slider with multiple discrete engagement portions, a rotation lever, a pawl, and a spring. This segmentation allows each component to perform a specific function while maintaining overall structural simplicity and ease of operation.
Solution Approach 2:
The spring automatically provides locking force to engage the pawl with the engagement portions, creating a self-locking mechanism. The system automatically maintains stable fixation without requiring continuous external force or complex control mechanisms, simplifying the overall structure.
3Device complexity
If friction-based sliding is used for the slider, then the structure remains simple, but the slider movement is resistant and requires excessive force
Solution Approach 1:
The patent replaces traditional friction-based sliding surfaces with roller elements that convert sliding friction into rolling friction. The rollers contact the slider and guide surface, enabling smooth movement with minimal force while maintaining structural simplicity.
4Force
If rollers are added to facilitate slider movement, then the sliding movement becomes smooth with reduced friction, but the device complexity increases
Solution Approach 1:
The roller mechanism is merged with the existing slider structure, where rollers are integrated into the slider body or guide surfaces. This combination provides smooth rolling movement while maintaining a compact and simple overall structure, avoiding excessive complexity.
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 stable and convenient adjustment of tilting angles, preventing the terminal body from swaying and ensuring secure positioning at various angles, enhancing user experience by maintaining the terminal body's stability and facilitating smooth sliding movements.
Implementation Method 1
a spring coupled to the stand and the rotation lever. The rotation lever includes a pawl releasably engaging one of the engagement portions of the slider. The spring biases the rotation lever toward the slider such that the pawl of the rotation lever engages one of the engagement portions
Implementation Method 2
a first roller, a second roller, a third roller and a fourth roller for facilitating a movement of the slider, wherein the stand includes an inner upper surface facing toward an upper surface of the slider and an inner lower surface facing toward a lower surface of the slider, and wherein the first roller is rotatably coupled to the inner upper surface of the stand and contacts the upper surface of the slider
