Bracket Design for Dual-Display Device Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with upper and lower displays are prone to damage from external shocks due to discontinuous surfaces where the support member connects the displays, leading to a degradation in grip and increased risk of window glass damage.
Innovation Solution
The electronic device incorporates a bracket with a minimal exposed area and a central area of larger volume to absorb shocks, reducing discontinuous surfaces and enhancing grip, while a reinforcing member can be added to reinforce the connecting area and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support member is provided to absorb external shocks, then the reliability of the display connection is improved, but the surface continuity deteriorates causing grip degradation
Solution Approach 1:
The bracket is designed with differentiated local properties: the exposed lateral surface area is minimized to maintain grip quality, while the internal volume (particularly the central area) is maximized to enhance shock absorption capability. This local quality differentiation resolves the contradiction between reliability and ease of operation.
Solution Approach 2:
The solution transitions from a two-dimensional surface consideration to a three-dimensional volume optimization. By designing the bracket with a minimal exposed surface area but a large internal volume (volume-to-surface-area ratio optimization), the invention achieves both grip quality and shock absorption performance simultaneously.
2Ease of operation
If the exposed area of the support member is reduced to improve grip, then the sense of grip is improved, but the shock absorption capability may be compromised
Solution Approach 1:
The bracket design applies local quality by creating distinct functional zones: a minimal exposed surface area for grip quality and a maximized internal volume for shock absorption. The central area specifically is designed with larger volume to enhance shock absorption while keeping the lateral exposed area minimal.
Solution Approach 2:
The invention resolves this contradiction by moving from surface-area optimization to volume optimization. The bracket achieves a favorable volume-to-surface-area ratio, where the internal volume is maximized for shock absorption while the external surface area is minimized for grip quality.
3Ease of operation
If a bracket with minimal exposed area is used, then grip degradation is reduced, but the structural complexity increases
Solution Approach 1:
The bracket is segmented into functionally distinct zones: an exposed lateral surface area minimized for grip quality, and an internal central area with larger volume for shock absorption. This segmentation allows each zone to optimize its specific function while maintaining overall structural integrity.
Solution Approach 2:
The bracket serves multiple functions simultaneously: it provides mechanical support for the display, absorbs external shocks through its optimized volume, and maintains grip quality through minimized exposed surface area. This multi-functionality reduces the need for additional separate components.
