Nested Kickstand Structure for Portable Terminal Device Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal devices lack a compact and portable protective solution that supports them on a desk while providing protection against accidental falls, as existing kickstands are bulky and not easily carried, and there is a need for a device that can stabilize and protect them during use.
Innovation Solution
A protective casing with a fixing structure and a kickstand assembly that includes a pull kickstand and an abutting kickstand, which form a stable triangle for support and can be hidden in a match groove for compact storage, utilizing a torsion spring for stabilization and grip straps with hook and loop fasteners for secure handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a kickstand is added to support the terminal device, then the device can be supported on a desk, but the device size increases and becomes difficult to carry
Solution Approach 1:
The kickstand components (pull kickstand and abutting kickstand) are nested within the match groove of the protective casing when not in use. The abutting kickstand can slide into the first slot or second slot depending on whether the pull kickstand is extended or retracted, creating a compact nested configuration that minimizes volume while maintaining full support functionality.
Solution Approach 2:
The kickstand employs dynamic components including a rotatable pull kickstand connected via a rotating slot, and an abutting kickstand that can slide between different positions (first slot, second slot, or match groove). This dynamic structure allows the kickstand to adapt between compact storage mode and extended support mode, resolving the contradiction between portability and support capability.
2Reliability
If a protective casing is added to prevent accidental falling, then device protection is improved, but device complexity increases
Solution Approach 1:
The protective casing is merged with the kickstand functionality by integrating the match groove, first slot, and second slot directly into the casing structure. The fixing structure with inner chuck and outer chuck is also integrated into the same casing body, combining protection and support functions into a single unified component rather than separate attachments.
Solution Approach 2:
The protective casing serves multiple functions simultaneously: it provides physical protection for the terminal device, contains the kickstand mechanism for support, includes the fixing structure for securing the device, and offers grip straps for handling. This multi-functionality reduces overall system complexity by eliminating the need for separate protective case, kickstand, and mounting components.
3Stability of the object's composition
If a fixed kickstand structure is used for support, then support stability is achieved, but the device cannot be easily carried
Solution Approach 1:
The kickstand uses dynamic elements including a pull kickstand that can rotate within a rotating slot, and an abutting kickstand that can slide between the first slot, second slot, and match groove. This dynamic design allows the structure to be compact during carrying and automatically stable when deployed for support, resolving the contradiction between portability and stability.
Solution Approach 2:
The kickstand is divided into separate functional segments: the pull kickstand with rotating slot for deployment, the abutting kickstand with first slot and second slot for positioning, and the match groove for storage. This segmentation allows each component to be optimized for both compact storage and stable support, with the ability to transition between states without requiring a large fixed structure.

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 compact, portable, and stable support system for terminal devices, allowing them to be easily carried and stored, while offering protection against falls and enabling versatile positioning through a rotatable design.
Implementation Method 1
a torsion spring is disposed at an end, connected to the abutting kickstand, of the pull kickstand, and has an end connected to the pull kickstand and an end connected to the abutting kickstand
Implementation Method 2
two ends of the grip straps are disposed on two sides of the match groove respectively, and two said grip straps are arranged and are provided with hook and loop fastener
