Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in connecting multiple components without gaps due to manufacturing tolerances in the buckle system, leading to incomplete connections.
Innovation Solution
The implementation of a resilient assembly and rotating lever system within the housing of the electronic device, where the first electronic component slides into an accommodating space and connects to a second component by overcoming the force of the resilient assembly, ensuring a tight connection without gaps through a handle and rotating lever mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a buckle is used to fix the first electronic component to the housing, then the component can be secured in position, but manufacturing tolerances cause gaps between connected components
Solution Approach 1:
The patent employs a resilient assembly that allows the connection structure to dynamically adjust to manufacturing tolerances. The resilient nature enables the system to compensate for dimensional variations while maintaining secure connection, transforming a static rigid connection into a dynamic adaptive one.
Solution Approach 2:
The patent changes the physical state of the connection by introducing resilience and elasticity. The resilient assembly can deform elastically to absorb dimensional discrepancies, changing the connection parameter from rigid fixed-position to flexible adjustable-position, thereby eliminating gaps caused by manufacturing tolerances.
2Manufacturing precision
If manufacturing tolerances are reduced to eliminate gaps, then connection precision improves, but manufacturing complexity and cost increase
Solution Approach 1:
The patent converts the harmful effect of manufacturing tolerances into a beneficial feature by designing the resilient assembly to expect and accommodate these tolerances. Rather than fighting against the tolerances, the design embraces them, allowing the connection to self-adjust and eliminate gaps without requiring ultra-precise manufacturing.
Solution Approach 2:
The resilient assembly acts as an intermediary element between the first electronic component and the housing. This intermediate component absorbs the dimensional discrepancies and provides a smooth transition, enabling gap-free connection without requiring the main components to be manufactured with higher precision.
3Manufacturing precision
If a resilient assembly and rotating lever system is used to eliminate gaps, then connection precision improves, but device complexity increases
Solution Approach 1:
The patent divides the connection function into separate modular components: a resilient assembly for absorption, a rotating lever for adjustment, and a handle for operation. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability and ease of assembly.
Solution Approach 2:
The rotating lever mechanism allows the connection to self-adjust and self-lock into the correct position. Once the handle is operated to initiate the connection, the lever system automatically rotates and secures the components together without requiring additional adjustment steps or external intervention, reducing operational complexity.

AI summary
An electronic device includes a housing, a first electronic component, a second electronic component, two resilient assemblies, and two rotating levers. The housing defines an accommodating space. The second electronic component is fixed in the accommodating space. Each rotating lever includes a first end and a second end. A distance between the second end and a rotation shaft is less than a distance between the first end and the rotation shaft. A handle is rotationally fixed on the first electronic component. When the first electronic component slides into the accommodating space, the handle is rotated toward the first electronic component, the handle drives the two rotating levers to rotate and resist against the resilient assemblies, and the handle overcomes an elastic force applied by the resilient assemblies onto the rotating levers, so that the first electronic component connects with the second electronic component without gaps.
