Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems lack effective methods to integrate totems with touch and wireless communication for detecting pressure and maintaining totem position during tilting of horizontal displays.
Innovation Solution
A system that includes a totem with a strain gauge and wireless interface for pressure sensing, coupled with a totem holder that secures the totem in place on a touchscreen display, allowing for adjustable positioning and rotation, enabling pressure inputs and maintaining stability during tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a totem is placed on a horizontal touchscreen display for interaction, then user input capability is improved, but the totem cannot maintain its position when the display is tilted
Solution Approach 1:
The system separates the totem holding function from the display structure by introducing a独立的 totem holder device. The holder consists of separate components including a clamp mechanism, adjustable arm, and mounting base, allowing independent positioning and stabilization of the totem without affecting the display structure itself.
Solution Approach 2:
The totem holder is pre-configured with adjustable positioning mechanisms and friction-based clamping features that allow the totem to be securely attached before tilting occurs. The holder maintains preset positions through preliminary mechanical engagement, ensuring stability when the display is tilted to various angles.
2Measurement precision
If pressure sensing is added to the totem for enhanced input detection, then input precision is improved, but device complexity increases
Solution Approach 1:
The system replaces complex mechanical pressure sensing mechanisms with electronic pressure sensors that provide accurate measurement through electrical signals. The sensor output is processed by a controller that translates pressure values into meaningful input commands, simplifying the overall system while maintaining high measurement precision.
Solution Approach 2:
A wireless communication module acts as an intermediary between the pressure sensor and the host device, transmitting sensor data without requiring physical connections. This intermediary layer simplifies the totem structure by eliminating complex wired interfaces while maintaining accurate pressure detection and transmission capabilities.

AI summary
An information handling system interacts with a totem through a touchscreen display, such as with movement of the totem or pressured applied on the totem. A totem holder manages totem position on the touchscreen display to maintain the totem in a desired location, such as to prevent sliding of the totem in the event of motion of the touchscreen display from a horizontal to a more vertical orientation.
