Problem
Individuals experience muscle fatigue, poor posture, and related health issues such as cervical spondylosis and carpal tunnel syndrome due to prolonged use of computers and other input devices, which lack effective hand and wrist support systems that integrate therapeutic modalities.
Innovation Solution
A hand support device designed for input apparatus like keyboards and laptops, providing structural support and integrating various therapeutic modalities such as electrotherapy, iontophoresis, and heat/cold therapy, allowing users to receive medical treatment while working without interrupting their activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users type on keyboards or use input devices for prolonged periods, then productivity is improved, but muscle fatigue and poor posture occur
Solution Approach 1:
The hand support device automatically adjusts to the user's hand position and provides therapeutic treatment without requiring user intervention. The device self-regulates support height and therapeutic modality delivery, allowing continuous typing while receiving passive treatment for muscle fatigue and posture correction.
Solution Approach 2:
The device provides preliminary ergonomic support and therapeutic intervention before significant muscle fatigue or posture damage occurs. By continuously supporting the hands and wrists in proper positions and delivering preventive therapeutic treatments, the device addresses potential harm before it manifests as serious health issues.
2Object-affected harmful factors
If users maintain correct sitting and typing posture, then health issues are prevented, but physical effort and stamina are required
Solution Approach 1:
The hand support device automatically maintains correct ergonomic posture by providing continuous mechanical support to the hands and wrists. The device self-adjusts to keep hands in proper positions, eliminating the need for users to consciously maintain posture and reducing the physical effort required to prevent cervical spondylosis and other posture-related health issues.
Solution Approach 2:
The device counteracts the effects of gravity and muscular effort by providing mechanical support that bears the weight of the hands and wrists. This anti-weight support allows hands to rest in correct ergonomic positions without requiring continuous muscular activation, thereby preventing posture-related health issues while minimizing physical effort.
3Object-affected harmful factors
If hand support device provides therapeutic modalities, then therapeutic relief is improved, but device complexity increases
Solution Approach 1:
The hand support device integrates multiple therapeutic modalities (electrical stimulation, ultrasonic therapy, magnetic therapy, laser therapy, and medicinal application) into a single universal platform. This multi-functional design allows the device to address various conditions including carpal tunnel syndrome, muscle fatigue, and posture-related issues through one integrated system, providing comprehensive therapeutic relief while managing complexity through unified architecture.
4Adaptability or versatility
If users switch input between applications for multi-tasking, then application control is improved, but workflow interruption occurs
Solution Approach 1:
The hand support device segments the typing surface into distinct zones corresponding to different applications or tasks. Each zone can be assigned to a specific application, allowing users to physically move their hands to different zones to switch between tasks without requiring software input switching. This spatial segmentation maintains workflow continuity by enabling seamless task transitions through hand movement alone.

AI summary
A hand support device, for an input apparatus such as typing apparatus like keyboard, notebook, laptop, or the like, includes an elongated hand supporting bridge unit, a support base assembly and a pillar and bar joint assembly. The support base assembly supports the hand supporting bridge unit directly over the keyboard along the keyboard from the right side to the left side of the keyboard so that the user can rest on and work, wherein the support base assembly comprises a first base unit and a second base unit adapted for positioning at two sides of the keyboard. The pillar and bar joint assembly is arranged to movably support by the first base unit and the second base unit in order for the hand supporting bridge unit to provide a transversal support for the user's upper extremities over the keyboard.
